AMD RDNA2 "Navi 21" GPU to Double CU Count Over "Navi 10"

AMD's RDNA2 graphics architecture, which sees real-time ray-tracing among other DirectX 12 Ultimate features, could see the company double the amount of stream processors generation-over-generation, according to a specs leak by _rogame. The increase in stream processors would fall in line with AMD's effort to increase performance/Watt by 50%. It may appear like the resulting SKUs finally measure up to the likes of the RTX 2080 Ti, but AMD has GeForce "Ampere" in its competitive calculus, and should the recent specs reveal hold up, the new "Navi 21" could end up being a performance-segment competitor to GeForce graphics cards based on the "GA104" ("TU104" successor), rather than a flagship-killer.

The RDNA2-based "Navi 21" GPU allegedly features 80 RDNA2 compute units amounting to 5,120 stream processors. AMD might tap into a refined 7 nm-class silicon fabrication node by TSMC to build these chips, either N7P or N7+. The die-size could measure up to 505 mm², and AMD could aim for a 50% performance/Watt gain over the "Navi 10." AMD could carve out as many as 10 SKUs out of the "Navi 21," but only three are relevant to the gamers. The SKU with the PCI device ID "0x731F: D1" succeeds the RX 5700 XT. The one bearing "0x731F: D3" succeeds the RX 5700, with a variant name "Navi 21 XL." The "Navi 21 XE" variant has a PCI ID of "0x731F: DF," and succeeds the RX 5600 XT.

Dell Updates its G3 and G5 Gaming Notebook Lines

Besides Alienware, Dell maintains a gaming notebook line under its main brand, with the G3 and G5, both endowed with 15.6-inch displays. The G5 15 SE is AMD-powered, featuring 15.6-inch Full HD 144 Hz displays, processor options that include the Ryzen 9 4900H, Ryzen 7 4800H, and Ryzen 5 4600H. This is the first notebook from Dell to feature the Radeon RX 5600M graphics based on "Navi 10." This notebook's Intel+NVIDIA alter-ego is the G15-5500, which comes with processor options that include the i5-10300H and i7-10750H; and various NVIDIA GeForce GPU options ranging from the GTX 1650 Ti to the RTX 2070 Super Max-Q. Memory options range between 8 GB to 32 GB; and storage between 128 GB to 1 TB NVMe SSD.

The G3 is Dell's entry-level gaming-grade notebook line. It offers 15.6-inch displays with Full HD resolutions, ranging between 60 Hz to 144 Hz, processor options that include the i5-10300H and i7-10750H, and graphics options ranging between the GTX 1650 and RTX 2060 (mobile). Memory options are either 8 GB single-channel or 16 GB dual-channel, both DDR4-2933. Dell has upped the game, doing away with HDD based storage options. The G3 starts with a 128 GB NVMe SSD, with capacities ranging up to 1 TB, and option for a second NVMe drive. Networking options include Killer 802.11ax and 1 GbE.

AMD Coming Around to Launching the Radeon RX 5600M and RX 5700M?

AMD is finally coming around to launching the Radeon RX 5600M and RX 5700M based on its 7 nm "Navi 10" silicon. The company has, until now, only shipped mobile GPUs using the smaller "Navi 14" chip. A scoop by Komachi Ensaka points to an upcoming notebook combining a Ryzen 4000-H processor an "Navi-10M" GPU. With the right combination of clock speeds and memory configuration, the RX 5600M could offer performance rivaling (or beating) the GeForce GTX 1660 Ti (mobile), and possibly on par with the RTX 2060 (mobile). The RX 5700M could compete with the upcoming RTX 2060 Super (mobile) and RTX 2070 (mobile). The RX 5600M could be a particularly important solution, as its desktop compatriot is designed for higher refresh-rate 1080p gaming. Much of the gaming notebook scene still revolves around 1080p, with innovations in the areas of refresh rates.

AMD gave both the RX 5600M and RX 5700M identical GPU core configurations to their desktop variants. The RX 5600M has 2,304 stream processors, 144 TMUs, 64 ROPs, and a 192-bit GDDR6 memory interface holding 6 GB of memory; while the RX 5700M tops it with 256-bit wide memory bus and 8 GB of memory. Both the RX 5700M and RX 5600M are configured with 12 Gbps memory frequency. The RX 5600M ticks at 1190 MHz (game), and 1265 MHz (boost), while the RX 5700M does 1620 MHz (game) and 1720 MHz (boost). Coming back to Komachi's leak about the Renoir + Navi 10M notebook, we predict a working implementation of AMD SmartShift technology. The company even made marketing graphics of this.

AMD to Debut 2nd Gen RDNA Architecture in 2020

AMD CEO Dr Lisa Su, in her Q4-2019 and FY-2019 earnings call, confirmed that the company debut its second-generation RDNA graphics architecture in 2020. "In 2019 we launched our new architecture in GPUs, it's the RDNA architecture, and that was the Navi-based products. You should expect those will be refreshed in 2020, and we will have our new next-generation RDNA architecture that will be part our 2020 lineup."

Second-gen RDNA, or RDNA2, is expected to leverage the new 7 nm+ (EUV) silicon fabrication process at TSMC, to dial up transistor-counts, clock-speeds, and performance. Among the two anticipated feature additions are VRS (variable rate shading) and possibly ray-tracing. The fabled "big Navi" silicon, a GPU larger than "Navi 10," is also on the cards, according to an earlier statement by Dr Su. More details about these upcoming graphics cards are expected to be put out in March, at the 2020 AMD Investor Day conference.

ASUS Gives Radeon RX 5600 XT the ROG Strix and TUF Gaming Treatment

ASUS is keeping its Radeon RX 5600 XT graphics card lineup trim, with just two SKUs, both of which are factory-overclocked. The lineup is led by the ROG Strix Radeon RX 5600 XT O6G, while its affordable sibling is the TUF Gaming X3 Radeon RX 5600 XT EVO. ASUS hasn't finalized the clock-speeds for either, as it's rumored that AMD is working with its partners to increase them across the board, to make the RX 5600 XT competitive against the GeForce RTX 2060. Both ASUS RX 5600 XT graphics cards are largely based on its RX 5700-series board designs as the RX 5600 XT is carved from the same 7 nm "Navi 10" ASIC.

The ROG Strix RX 5600 XT O6G features the company's premium triple-slot DirectCU III cooling solution with three Axial-Tech fans, idle fan-stop, plenty of RGB bling on the cooler shroud and metal back-plate, and a high-grade VRM solution that pulls power from a combination of 8-pin and 6-pin PCIe power connectors. The TUF Gaming X3 RX 5600 XT EVO, on the other hand, also features a triple-slot design, the TUF X3 cooling solution with three Axial-Tech fans (the one in the middle is smaller than the others); idle fan-stop, and a metal back-plate. This card pulls power from a single 8-pin PCIe power connector, unlike the ROG Strix.

Expect High-end Navi: AMD CEO

At a Q&A session with the tech press in Las Vegas, AMD CEO Dr Lisa Su raised hopes of a high-end graphics card based on its "Navi" family of GPUs. Responding to a specific question by Gordon Ung from PC World on whether there will be a high-end competitor in the discrete graphics space, Dr Su stated that one should expect a "high-end Navi." Dr Su states: "I know those on Reddit want a high end Navi! You should expect that we will have a high-end Navi, and that it is important to have it. The discrete graphics market, especially at the high end, is very important to us. So you should expect that we will have a high-end Navi, although I don't usually comment on unannounced products."

For months now, it's been speculated that AMD has been working on a larger GPU die than "Navi 10." In 2020, AMD is expected to release the "Navi 20" familly of GPUs built on 7 nm+ (EUV) node, based on the RDNA2 graphics architecture. The key design goals of RDNA2 are expected to be support for at least tier-1 variable-rate shading (VRS), and possibly hardware-accelerated ray-tracing. It's possible that "high-end Navi" belongs to this family of GPUs.

ASRock Radeon RX 5600 XT Phantom Gaming OC Graphics Card Pictured

Here's the first press-shot of an upcoming Radeon RX 5600 XT custom-design graphics card, this one from ASRock. The RX 5600 XT Phantom Gaming OC appears to combine a compact PCB with a long triple-fan cooling solution that's 29 cm in length. The cooling solution features an aluminium fin-stack heatsink that's ventilated by a trio of 80 mm spinners. The card draws power from a single 8-pin PCIe power connector, indicating a significantly lower power draw target than the RX 5700-series. The card's box confirms 6 GB of GDDR6 memory, and factory-overclocked speeds, which according to VideoCardz are 1560 MHz gaming.

From an older report, we know that the RX 5600 XT is designed to compete with NVIDIA's GeForce GTX 1660 Ti. It's armed with 2,304 stream processors, 144 TMUs, possibly 48 ROPs, and a 192-bit wide GDDR6 memory interface holding 6 GB of memory, which ticks at 12 Gbps. The RX 5600 XT appears to be carved from the 7 nm "Navi 10" silicon, with a quarter of its memory interface disabled. AMD is expected to debut the card at its International CES 2020 presser, later this month.

AMD to Outpace Apple as TSMC's Biggest 7nm Customer in 2020

AMD in the second half of 2020 could outpace Apple as the biggest foundry customer of TSMC for its 7 nm silicon fabrication nodes (DUV and EUV combined). There are two key factors contributing to this: AMD significantly increasing its orders for the year; and Apple transitioning to TSMC's 5 nm node for its A14 SoC, freeing up some 7 nm allocation, which AMD grabbed. AMD is currently tapping into 7 nm DUV for its "Zen 2" chiplet, "Navi 10," and "Navi 14" GPU dies. The company could continue to order 7 nm DUV until these products reach EOL; while also introducing the new "Renoir" APU die on the process. The foundry's new 7 nm+ (EUV) node will be utilized for "Zen 3" chiplets and "Navi 2#" GPU dies in 2020.

Currently, the top-5 customers for TSMC 7 nm are Apple, HiSilicon, Qualcomm, AMD, and MediaTek. Barring AMD, the others in the top-5 build mobile SoCs or 4G/5G modem chips on the node. AMD is expected to top the list as it scales up orders with TSMC. In the first half of 2020, TSMC's monthly output for 7 nm is expected to grow to 110,000 wafers per month (wpm). Apple's migration to 5 nm in 2H-2020, coupled with capacity-addition could take TSMC's 7 nm output to 140,000 wpm. AMD has reportedly booked the entire capacity-addition for 30,000 wpm, taking its allocation up to 21% in 2H-2020. Qualcomm is switching to Samsung for its next-generation SoCs and modems designed for 7 nm EUV. NVIDIA, too, is expected to built its next-gen 7 nm EUV GPUs on Samsung instead of TSMC. These moves by big players could free up significant foundry allocation at TSMC for AMD's volumes to grow in 2020.

AMD Radeon RX 5600 XT Features 2,304 Stream Processors

AMD's upcoming Radeon RX 5600 XT graphics card features the same exact stream processor count as the $350 RX 5700, according to a leaked specs sheet of a an AIB partner's custom-design graphics card. With a stream processor count of 2,304, it's safe to assume that the RX 5600 XT is based on the same 7 nm "Navi 10" silicon as the RX 5700 series. What set the RX 5600 XT apart from the RX 5700, besides lower clock-speeds, is the memory subsystem, which is severely stripped down. The Radeon RX 5600 XT will be equipped with 6 GB of GDDR6 memory across a 192-bit wide memory interface. What's more, the memory ticks at 12 Gbps, compared to 14 Gbps on the RX 5700 series.

With these specs, the RX 5600 XT has 288 GB/s of memory bandwidth at its disposal, same as NVIDIA's GeForce GTX 1660 Ti. In contrast, with 8 GB of 256-bit GDDR6 running at 14 Gbps, the RX 5700 enjoys 448 GB/s. The specs sheet suggests that AMD has also dialed down the engine clock-speeds (GPU clocks) a bit, with up to 1620 MHz boost, up to 1460 MHz gaming, and 1235 MHz base. With these specs, it's highly likely that the RX 5600 XT outperforms the GTX 1660 Ti and gets close to the RTX 2060. It all boils down to pricing. The RX 5500 XT is a decent GTX 1650-series alternative with a lukewarm price thanks to NVIDIA's aggressive product-stack management by getting its partners to lower prices of the GTX 1660 and GTX 1660 Super. It would be interesting to see if AMD can outfox NVIDIA in the sub-$300 market.

AMD RX 5600 XT Poised to Offer Vega 56-like Performance, Possible Specs Rumored

AMD's upcoming RX 5600 XT will bring about a much needed power increase over the current baseline RX 5500 series, slotting smoothly between it and the mainstream, high-performance RX 5700 and RX 5700 XT. New benchmarks spotted by Videocardz place AMD's upcoming graphics card (which could feature a 6 GB VRAM with higher capacities likely to be offered as well) some 35% ahead of the RX 5500, as well as on the overall performance level of AMD's RX Vega 56. That AMD card debuted at $399 and now has performance 8% to 15% higher than NVIDIA's current GTX 1660 SUPER, exactly where AMD would want the RX 5600 XT's performance to land.

Other details come courtesy of another publication, where Igor Wallosseck over at Igor's Lab says that AMD could be looking at harvesting the Navi 10 dies that power the company's RX 5700 XT and RX 5700 by disabling one of four Asynchronous Compute Engines (ACEs). These four ACEs are found two each on one of Navi's Shader Engines (SEs), and disabling one ACE and subordinate hardware from the full Navi 10's 40 RDNA Units, 2,560 Stream Processors (SPs), 160 texture mapping units (TMUs) and 64 render output units (ROPs) would make up for an RX 5600 XT with 30 RDNA CUs, 1,920 SPs, 120 TMUs, 48 ROPs and expected 3 MB of L2 cache. AMD could be looking to position the AMD RX 5600 XT in the $249 price range, since top tier RX 5500 XT tend to go for $200.

PowerColor Readies SFF-friendly Radeon RX 5700 ITX: Single 8-pin, Idle-Fan-Off

PowerColor is readying a small form-factor friendly custom-design Radeon RX 5700 graphics card, called simply the PowerColor RX 5700 ITX. With a length of 17.5 cm, standard 11 cm height, and strictly 2-slot thickness, the card uses a dense aluminium fin-stack heatsink with four 6 mm-thick nickel-plated copper heat pipes that make direct contact with the GPU at the base, ventilated by a single 80 mm fan. More interestingly, the card draws power from a single 8-pin PCIe power connector (225 W max power input for the connector + PCIe slot).

Unsurprisingly, the PowerColor RX 5700 ITX sticks to AMD-reference clock-speeds of 1465 MHz base, 1625 MHz gaming, and 1725 MHz boost, with the memory ticking at 14 Gbps (GDDR6-effective). Despite its compact cooling solution, the card does not skimp on idle-fan-off. Display outputs include two DisplayPort 1.4, and one HDMI 2.0. Based on the 7 nm "Navi 10" silicon, the RX 5700 features 2,304 stream processors across 36 RDNA compute units, 144 TMUs, 64 ROPs, and a 256-bit wide GDDR6 memory interface, holding 8 GB of memory. PowerColor didn't reveal pricing of the card, as it will formally launch it later this month.

AMD Radeon RX 5600 Series SKUs Feature 6GB and 8GB Variants

AMD's Radeon RX 5600-series could see the company take on the top-end of NVIDIA's GeForce 16-series, such as the GTX 1660 Super and the GTX 1660 Ti. A report from earlier this month pegged a December 2019 product announcement for the RX 5600-series and subsequent availability in the weeks following. Regulatory filings by AMD AIB (add-in board) partners with the Eurasian Economic Commission (EEC) shed more light on the product differentiation within the RX 5600 series. The filings reveal that the RX 5600 and RX 5600 XT feature 6 GB and 8 GB sub-variants.

The regulatory filing by ASUS references products across its ROG Strix, TUF Gaming, and Dual lines of graphics cards. As mentioned in the older report, we expect AMD to carve the RX 5600 series out of the larger "Navi 10" silicon, by disabling many more RDNA compute units than the RX 5700, and narrowing the GDDR6 memory bus to 192-bit for the 6 GB variants. AMD has an opportunity to harvest "Navi 10" chips down to stream processor counts such as 1,792 (28 CUs) or 2,048 (32 CUs). It also has the opportunity to use cost-effective 12 Gbps GDDR6 memory chips.

AMD to Unveil Radeon RX 5500 XT and RX 5600 Series in December

AMD is expected to bolster its mid-thru-performance segments of graphics cards with a few new product announcements in December. To begin with, the Radeon RX 5500 XT, which maxes out the 24 RDNA compute units on the "Navi 14" silicon, could see an early-December announcement, possibly ahead of the mid-December release of the RX 5500 to the AIB (add-in board) retail channel. Next up, is the new RX 5600 series, which enables AMD to capture $200-$300 price-points, competing with the likes of the GeForce GTX 1660 Super and GTX 1660 Ti.

There's no word on how what silicon the RX 5600 series is based on, but VideoCardz reports that the series topping RX 5600 XT has 6 GB of GDDR6 memory across a 192-bit wide memory interface. We expect that the RX 5600-series will carved out of the "Navi 10" silicon by disabling many RDNA compute units and narrowing its memory bus. Given that the RX 5500 XT has 1,536 stream processors and the RX 5700 has 2,304, AMD's wiggle room is somewhere between the two, with stream processor counts of 2,048 or 1,920 being plausible for the RX 5600 XT, and 1,792 for the RX 5600, if it exists. Availability of the RX 5600 series is slated for January 2020.

NVIDIA Partners Order Fresh GeForce RTX 2070 Chips as they Expect RX 5700 XT Inventories to Slump

NVIDIA's add-in card partners are ordering fresh stocks of GeForce RTX 2070 graphics chips even as the performance-segment of the GPU market has changed with AMD's introduction of its Radeon RX 5700 series "Navi," according to a Gamers Nexus report citing sources among NVIDIA partners. NVIDIA partners are expecting a slump in AMD's RX 5700 series graphics card inventories, particularly that of the RX 5700 XT, to create a price-point at which to sell the RTX 2070. NVIDIA partners expect RX 5700 XT inventories to run slim as supply of the 7 nm "Navi 10" chips from foundry-partner TSMC may not satiate the SKU's reportedly high demand.

NVIDIA's current product stack has the original RTX 2060 at $349, the RTX 2060 Super at $399, and the RTX 2070 Super at $499. The RTX 2070, which is outperformed by the $399 Radeon RX 5700 XT, was practically phased out from NVIDIA's product-stack as it was succeeded by the RTX 2070 Super at its $499 price-point. With the RTX 2070 making a comeback, it would be interesting to see what its price-point will be. There is a gap between the $399 RTX 2060 Super, and the $499 RTX 2070 Super, although the performance gap between the RTX 2060 Super and the RTX 2070 is a paltry 4 percent, which is easily closed by moderately overclocking the RTX 2060 Super. As of this writing, both pricing and availability of the RX 5700 XT appear normal.

GIGABYTE Readies Several Radeon RX 5500 Series Graphics Cards

GIGABYTE has filed regulatory filings with the Eurasian Economic Commission (EEC) for several Radeon RX 5500-series graphics cards, including as many as six models based on the range-topping RX 5500 XT. The filing confirms that the RX 5500 XT is real, and that all six models from GIGABYTE feature 8 GB of GDDR6 memory. The RX 5500 XT, or Navi 10 XTX is rumored to feature 24 RDNA compute units, making up 1,536 stream processors, and a 128-bit wide GDDR6 memory interface, holding 8 GB of memory. AMD possibly hopes to capture sub-$250 price points with this SKU, given that NVIDIA preempted it with the $230 GeForce GTX 1660 Super.

Among the six models, going by GIGABYTE naming conventions, are cards based on the company's WindForce 2X cooler, the Gaming OC SKU that possibly has the larger WindForce 3X cooler, and simpler models that stick to reference clock-speeds. GIGABYTE has been rather restrained with its AMD "Navi" graphics card series, with only two custom-design RX 5700-series graphics cards so far. The same EEC filing also references several additional RX 5700-series SKUs from the company, including some based on its coveted Aorus Gaming brand.

TechPowerUp GPU-Z v2.26.0 Released

Today we released the latest version of TechPowerUp GPU-Z, the popular graphics subsystem information, monitoring, and diagnostic utility. Version 2.26.0 adds support for new GPUs, introduces new features, and fixes problems with existing ones. To begin with, support is added for AMD Radeon RX 5500 and RX 5500M, TU104-based NVIDIA GeForce RTX 2060 (non-Super), and Quadro P520. Fake detection has been added for various "Kepler" based GTX 10-series knockoffs.

With this release we fixed an application crash during BIOS extraction on nearly all NVIDIA GPUs. Another crash that appears when the application is launched on machines with AMD "Navi" GPUs without drivers installed. The ASUS ROG skin has been fixed to properly show the "Close" button in the bottom. We also improved the memory junction temperature tooltip on AMD "Navi" to denote that the hottest chip's junction temperature is being reported, and not an average across all chips. Last version's AMD Navi fan-stop fix has been reverted since AMD fixed the issue since their 19.9.1 drivers. PCIe and CrossFire state detection has been fixed for AMD "Navi" and "Vega 20" based graphics cards. Grab it from the link below.

AMD "Navi 14" and "Navi 12" GPUs Detailed Some More

The third known implementation of AMD's "Navi" generation of GPUs with RDNA architecture is codenamed "Navi 14." This 7 nm chip is expected to be a cut-down, mainstream chip designed to compete with a spectrum of NVIDIA GeForce GTX 16-series SKUs, according to a 3DCenter.org report. The same report sheds more light on the larger "Navi 12" GPU that could power faster SKUs competing with the likes of the GeForce RTX 2080 and RTX 2080 Super. The two follow the July launch of the architecture debut with "Navi 10." There doesn't appear to be any guiding logic behind the numerical portion of the GPU codename. When launched, the pecking order of the three Navi GPUs will be "Navi 12," followed by "Navi 10," and "Navi 14."

"Navi 14" is expected to be the smallest of the three, with an estimated 170 mm² die-area, about 24 RDNA compute units (1,536 stream processors), and expected to feature a 128-bit wide GDDR6 memory interface. It will be interesting to see how AMD carves out an SKU that can compete with the GTX 1660 Ti, which has 6 GB of 192-bit GDDR6 memory. The company would have to wait for 16 Gbit (2 GB) GDDR6 memory chips, or piggy-back eight 8 Gbit chips to achieve 8 GB, or risk falling short of recommended system requirements of several games at 1080p, if it packs just 4 GB of memory.

AMD "Renoir" APU to Support LPDDR4X Memory and New Display Engine

AMD's next-generation "Renoir" APU, which succeeds the company's 12 nm "Picasso," will be the company's truly next-generation chip to feature an integrated graphics solution. It's unclear as of now, if the chip will be based on a monolithic die, or if it will be a multi-chip module of a 7 nm "Zen 2" chiplet paired with an enlarged I/O controller die that has the iGPU. We're getting confirmation on two key specs - one, that the iGPU will be based on the older "Vega" graphics architecture, albeit with an updated display engine to support the latest display standards; and two, that the processor's memory controller will support the latest LPDDR4X memory standard, at speeds of up to 4266 MHz DDR. In comparison, Intel's "Ice Lake-U" chip supports LPDDX4X up to 3733 MHz.

Code-lines pointing toward "Vega" graphics with an updated display controller mention the new DCN 2.1, found in AMD's new "Navi 10" GPU. This controller supports resolutions of up to 8K, DSC 1.2a, and new resolutions of 4K up to 240 Hz and 8K 60 Hz over a single cable, along with 30 bits per pixel color. The multimedia engine is also suitably updated to VCN 2.1 standard, and provides hardware-accelerated decoding for some of the newer video formats, such as VP9 and H.265 at up to 90 fps at 4K, and 8K up to 24 fps, and H.264 up to 150 fps at 4K. There's no word on when "Renoir" comes out, but a 2020 International CES unveil is likely.

110°C Hotspot Temps "Expected and Within Spec", AMD on RX 5700-Series Thermals

AMD this Monday in a blog post demystified the boosting algorithm and thermal management of its new Radeon RX 5700 series "Navi" graphics cards. These cards are beginning to be available in custom-designs by AMD's board partners, but were only available as reference-design cards for over a month since their 7th July launch. The thermal management of these cards spooked many early adopters accustomed to seeing temperatures below 85 °C on competing NVIDIA graphics cards, with the Radeon RX 5700 XT posting GPU "hotspot" temperatures well above 100 °C, regularly hitting 110 °C, and sometimes even touching 113 °C with stress-testing application such as Furmark. In its blog post, AMD stated that 110 °C hotspot temperatures under "typical gaming usage" are "expected and within spec."

AMD also elaborated on what constitutes "GPU Hotspot" aka "junction temperature." Apparently, the "Navi 10" GPU is peppered with an array of temperature sensors spread across the die at different physical locations. The maximum temperature reported by any of those sensors becomes the Hotspot. In that sense, Hotspot isn't a fixed location in the GPU. Legacy "GPU temperature" measurements on past generations of AMD GPUs relied on a thermal diode at a fixed location on the GPU die which AMD predicted would become the hottest under load. Over the generations, and starting with "Polaris" and "Vega," AMD leaned toward an approach of picking the hottest temperature value from a network of diodes spread across the GPU, and reporting it as the Hotspot.

Possible XFX Radeon RX 5700-series Graphics Card Pictured

Here's the first picture of a possible custom-design Radeon RX 5700-series graphics card by XFX. The company could leverage this common board design to develop both Radeon RX 5700 XT and RX 5700 products. The design involves a large custom-design cooling solution that uses an aluminium fin-stack heatsink that's ventilated by a pair of large 100 mm fans. It's likely that the card will offer idle fan-stop looking at the size of the heatsink and the idle power-draw of the "Navi 10" silicon. The card could also feature some RGB LED embellishments. At this point it's not known if XFX has designed its own custom-design PCB for the "Navi 10," or whether it's using a reference- or close-to-reference PCB design. AMD's add-in board partners are expected to launch custom-design RX 5700-series products in August.

AMD Readies Larger 7nm "Navi 12" Silicon to Power Radeon RX 5800 Series?

AMD is developing a larger GPU based on its new "Navi" architecture to power a new high-end graphics card family, likely the Radeon RX 5800 series. The codename "Navi 12" is doing rounds on social media through familiar accounts that have high credibility with pre-launch news and rumors. The "Navi 10" silicon was designed to compete with NVIDIA's "TU106," as its "XT" and "Pro" variants outperform NVIDIA's original RTX 2060 and RTX 2070, forcing it to develop the RTX 20 Super series, by moving up specifications a notch.

Refreshing its $500 price-point was particularly costly for NVIDIA, as it was forced to tap into the 13.6 billion-transistor "TU104" silicon to carve out the RTX 2070 Super; while for the RTX 2060 Super, it had to spend 33 percent more on the memory chips. With the "Navi 12" silicon, AMD is probably looking to take a swing at NVIDIA's "TU104" silicon, which has been maxed out by the RTX 2080 Super, disrupting the company's $500-700 lineup once again, with its XT and Pro variants. There's also a remote possibility of "Navi 12" being an even bigger chip, targeting the "TU102."

AMD Navi Radeon Display Engine and Multimedia Engine Detailed

Two of the often overlooked components of a new graphics architecture are the I/O and multimedia capabilities. With its Radeon RX 5700-series "Navi 10" graphics processor, AMD gave the two their first major update in over two years, with the new Radeon Display Engine, and Radeon Multimedia Engine. The Display Engine is a hardware component that handles the graphics card's physical display I/O. The Radeon Multimedia Engine is a set of fixed-function hardware that provides CODEC-specific acceleration to offload your CPU.

The Navi Radeon Display Engine features an updated DisplayPort 1.4 HDR implementation that's capable of handling 8K displays at 60 Hz with a single cable. It can also handle 4K UHD at 240 Hz with a single cable. These also include HDR and 10-bit color. It achieves this by implementing DSC 1.2a (Display Stream Compression). The display controller also supports 30 bpp internal color-depth. The HDMI implementation remains HDMI 2.0. The multi-plane overlay protocol (MPO) implementation now supports a low-power mode. This should, in theory, reduce the GPU's power draw when idling or playing back video.

AMD Radeon RX 5700 XT Confirmed to Feature 64 ROPs: Architecture Brief

AMD "Navi 10" is a very different GPU from the "Vega 10," or indeed the "Polaris 10." The GPU sees the introduction of the new RDNA graphics architecture, which is the first big graphics architecture change on an AMD GPU in nearly a decade. AMD had in 2011 released its Graphics CoreNext (GCN) architecture, and successive generations of GPUs since then, brought generational improvements to GCN, all the way up to "Vega." At the heart of RDNA is its brand new Compute Unit (CU), which AMD redesigned to increase IPC, or single-thread performance.

Before diving deeper, it's important to confirm two key specifications of the "Navi 10" GPU. The ROP count of the silicon is 64, double that of the "Polaris 10" silicon, and same as "Vega 10." The silicon has sixteen render-backends (RBs), these are quad-pumped, which work out to an ROP count of 64. AMD also confirmed that the chip has 160 TMUs. These TMUs are redesigned to feature 64-bit bi-linear filtering. The Radeon RX 5700 XT maxes out the silicon, while the RX 5700 disables four RDNA CUs, working out to 144 TMUs. The ROP count on the RX 5700 is unchanged at 64.

AMD E3 Next Horizon Event: Live Blog

It's been a very busy May-June for AMD as the company pushes out its major client-segment product lines spread across Computex 2019, and E3 2019. At Computex, the company focused on its 3rd generation Ryzen "Zen 2" desktop processors, and led its partners to show us a galaxy of new motherboards based on the AMD X570 chipset. It turns out that the company was saving a handful processor SKUs focused on gamers for E3.

The second important product launch of course is Radeon RX 5700 series, based on AMD's new "Navi 10" silicon on which its new RDNA graphics architecture debuts. With its AIB (add-in board) partners expected to be allowed to make custom-design cards, and based on what little nuggets of information AMD put out, "Navi" promises to stir up a key performance-segment price-band that's currently held by NVIDIA's GeForce RTX 2070 and RTX 2060. The AMD keynote will see the company CEO Dr. Lisa Su and her top execs take centerstage to make some big announcements. With E3 being a purely entertainment / client-segment forum, the AMD keynote promises not bore with tiresome topics such as AI, self-driving cars, etc.
2:30 PM PDT: Ahead of its keynote, AMD posted a teaser video of its new RDNA graphics architecture on YouTube.

AMD Radeon RX 5700 XT Slide Leaked: Picture and Specs

Ahead of its official reveal at AMD's E3 2019 keynote scheduled for 3 PM (Pacific) later today, VideoCardz scored a key slide that spills the beans on AMD's next performance-segment graphics card, the Radeon RX 5700 XT. This card is based on the 7 nm "Navi 10" silicon, and is its "XT" (maxed-out) SKU. Its reference-design board design in the slide reveals a return to a lateral-blower type cooling solution that now has a prettier cooler shroud with silver ridges and Radeon logos on two sides, one of which is illuminated, with a possible RGB LED accent that runs along the top of the card.

The specifications revealed point to 40 compute units. Unless AMD changed the stream processor count per CU with the RDNA architecture from 64, this works out to 2,560 stream processors. When combined with a stellar engine boost frequency of up to 1905 MHz, the GPU has a compute throughput of 9.75 TFLOP/s, which is 37 percent higher than that of the RX 590, but 27 percent lower than the Radeon VII, and roughly similar to the RX Vega 56. The RX 5700 XT is armed with 8 GB of GDDR6 memory, although the slide won't mention memory clock-speeds or bandwidth. AMD may disclose pricing and availability in its keynote address later today.
