AMD Releases Radeon Software 19.7.5 - Still No Fix to Elevated RX 5700 Idle Fan-Noise

AMD ended July with the fifth release of Radeon Software Adrenalin 2019 Edition for the month, version 19.7.5 beta. The drivers address an application crash noticed with "Wolfenstein: Youngblood" on Radeon RX 5700 series graphics cards, which is the only item on the change-log. AMD identified a number of new "known issues," but the 50 percent increased idle fan-speeds on RX 5700 series isn't one of them.

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 Reports Second Quarter 2019 Financial Results

AMD (NASDAQ:AMD) today announced revenue for the second quarter of 2019 of $1.53 billion, operating income of $59 million, net income of $35 million and diluted earnings per share of $0.03. On a non-GAAP basis, operating income was $111 million, net income was $92 million and diluted earnings per share was $0.08.

"I am pleased with our financial performance and execution in the quarter as we ramped production of three leadership 7nm product families," said Dr. Lisa Su, AMD president and CEO. "We have reached a significant inflection point for the company as our new Ryzen, Radeon and EPYC processors form the most competitive product portfolio in our history and are well positioned to drive significant growth in the second half of the year."

AMD Radeon 19.7.3 Drivers Increase RX 5700 Series Idle Fan Speeds by Over 50%

AMD's recent Radeon Software Adrenalin 19.7.3 beta drivers appear to break the fan settings of reference-design Radeon RX 5700 XT and RX 5700 cards. All earlier drivers for these cards offered good idle fan-speeds, despite the lack of fan-stop, with the fan of Radeon RX 5700 XT idling around 14% or 740 RPM. Once the new 19.7.3 drivers are installed, the fan-speed never drops below 23% or 1,170 RPM. This phenomenon can be observed even on the reference RX 5700, which now idles at 22% fan-speed, or 1,130 RPM, up from 13% or 685 RPM. This increases fan speed RPMs by 66% for the RX 5700 XT and +57% for the RX 5700. To demonstrate this bug, we first installed reference RX 5700 XT and RX 5700 cards with 19.7.2 drivers, and logged their idle fan-speeds using GPU-Z. Next we switched to 19.7.3 and recorded the same data for a completely idle card, sitting at the desktop.

The raised idle fan-speeds keep the GPU cooler when idling. With 19.7.2, the GPU hotspot was observed to be around 42 °C. Booting from 19.7.3, we see hotspot temperature settle down to around 38 °C for the RX 5700 XT, and to 37 °C for the RX 5700. Such a small difference at such low temperatures really shouldn't have any effect on longevity or anything else. On the other hand, higher fan-speeds also mean that the idle fan-noise levels are noticeably higher, and no longer match the idle fan-speeds measured in launch-day reviews by TechPowerUp and other tech publications.
Update (30/07): We can confirm that the 19.7.4 drivers released late Monday do not fix this issue.

AMD Releases Radeon Software Adrenalin 19.7.3

AMD today posted the latest version of Radeon Software Adrenalin 2019 Edition. Version 19.7.3 beta comes in the nick of time with optimization for "Wolfenstein: Youngblood," with up to 13 percent higher frame-rates on offer compared to 19.7.2. The release also adds Radeon GPU Profiler and Microsoft PIX for Radeon RX 5700 series. AMD also expanded its Vulkan API support by adding six new extensions, two of which are AMD-exclusive, and four standard. These include VK_EXT_display_surface_counter, VK_AMD_pipeline_compiler_control, VK_AMD_shader_core_properties2, VK_EXT_subgroup_size_control, VK_KHR_imageless_framebuffer, and VK_KHR_variable_pointers.

Among the fixed issues are "League of Legends" failing to launch with RX 5700-series on Windows 7; RX 5700 series experiencing application crashes with DirectX 9 applications after an Express Upgrade, Windows Mixed Reality not launching with Radeon Image Sharpening enabled on RX 5700-series; out-of-sync audio with ReLive VR; incorrect Radeon Wattman power gauge values for Radeon VII; AMD Log Utility not correctly installing; performance drops with Radeon Anti-Lag; minor stutter noticed in the first few minutes of "Fotnite" gameplay on RX 5700-series; Radeon Overlay flickering over Vulkan apps with Image Sharpening enabled; and some corruption noticed when running Adobe Premier Pro 2019 benchmarks.

EK Launches EK-Vector Special Edition RX 5700-series Water Blocks

EK Water Blocks, the leading premium computer liquid cooling gear manufacturer, is releasing a Special Edition of the EK-Vector Radeon RX 5700 +XT water block that is compatible with reference design AMD Radeon RX 5700 and 5700 XT graphics cards. This efficient and elegant-looking cooling made to look like the AMD Radeon RX 5700 XT factory cooler will allow your high-end Navi series graphics card to reach higher boost clocks, thus providing more overclocking headroom and more performance during gaming or other GPU intense tasks.

With the fabrication process of 7 nm, the chips become very small. The size of the new Navi GPU cores in RX 5700 and 5700 XT is only 251 mm while the 14 nm Vega GPUs were 495 mm in size. Almost double. The Navi GPU is more efficient, but still, the thermal density is increased. Which is why these small chips benefit a lot from a more efficient way of cooling via our water blocks.

RX 5700 XT Navi Crosses 2.2 GHz Thanks to Custom SoftPowerPlay Table Registry-Mod

Igor Wallossek of Igor'sLAB Germany postulated a method by which an AMD Radeon RX 5700 XT "Navi" graphics card can be made to run at clock-speeds of over 2.20 GHz (engine clock), thanks to custom SoftPowerPlay Tables (SPPTs) deployed by modifications to the Windows Registry. The AMD Radeon driver is designed such that it reads PowerPlay tables from the video-BIOS of an RX 5700-series graphics card the first time it's detected, and writes it onto the Windows Registry for quick-reference. This is called a SoftPowerPlay Table or SPPT. It's the modification of SPPTs that allows you to manipulate the power limits of RX 5700-series graphics cards, and achieve higher engine clocks than the 2150 MHz engine-clock limit of the RX 5700 XT, which is set at just 1850 MHz for the RX 5700.

Wallossek's mod involves preparing your Windows Registry with a driver cleaner such as DDU, downloading and applying Registry files for various new power-limit targets you want. The table below details the various power-limit and clock headroom on offer from each kind of registry file. There's also a registry file that cleans up your Windows Registry of any SPPTs, if you decide to roll-back your mod. You can inspect a registry file by opening it in a plaintext viewer such as Notepad. Find links to the SPPT mods, and the Registry Cleanup in the source link below. You can also watch a video presentation by Wallossek in German language here. You make any changes to your machine at your own risk, be sure to have proper custom cooling for your graphics card.

AMD Retires the Radeon VII Less Than Five Months Into Launch

AMD has reportedly discontinued production of its flagship Radeon VII graphics card. According to a Cowcotland report, AMD no longer finds it viable to produce and sell the Radeon VII at prices competitive to NVIDIA's RTX 2080, especially when its latest Radeon RX 5700 XT performs within 5-12 percent of the Radeon VII at less than half its price. AMD probably expects custom-design RX 5700 XT cards to narrow the gap even more. The RX 5700 XT has a much lesser BOM (bill of materials) cost compared to the Radeon VII, due to the simplicity of its ASIC, a conventional GDDR6 memory setup, and far lighter electrical requirements.

In stark contrast to the RX 5700 XT, the Radeon VII is based on a complex MCM (multi-chip module) that has not just a 7 nm GPU die, but also four 32 Gbit HBM2 stacks, and a silicon interposer. It also has much steeper VRM requirements. Making matters worse is the now-obsolete "Vega" architecture it's based on, which loses big time against "Navi" at performance/Watt. The future of AMD's high-end VGA lineup is uncertain. Looking at the way "Navi" comes close to performance/Watt parity with NVIDIA on the RX 5700, AMD may be tempted to design a larger GPU die based on "Navi," with a conventional GDDR6-based memory sub-system, to take another swing at NVIDIA's high-end.

ASUS to Release Custom NAVI GPUs in September

With the launch of AMD's Radeon RX 5700 and 5700 XT "Navi" graphics cards, we got a nice improvement to the mid-range GPU segment. However, the launch was only followed by board partners releasing reference designs with the major change being either a sticker of different cooler accent, with no sign of custom board designs.

In a blog post on Edge UP, ASUS said that "Our initial Navi offerings will use AMD's reference cooler design and clock speeds, but we'll be tweaking, tuning, and powering up these new Radeons with coolers of our own design soon. Stay tuned for more details in September." This means that custom cards for Radeon RX 5700 and 5700 XT are arriving later than what we previously thought. It was believed that custom designs from AIBs would arrive some time in August, but the Edge UP post now contradicts that claim. In order to find out more, we would have to wait until August at least. Additionally, it may be possible that a "paper launch" will happen in August, while the general availability is targeted for September.

EK Teases its Premium Full-coverage Water Block for AMD Navi

It turns out that the EK-Vector isn't the only water-block family to feature models compatible with AMD Radeon RX 5700-series graphics cards. The Slovenian water-cooling major has plans for a truly unique block design for "Navi," building on AMD's "bend the rules" design language used on its reference RX 5700 XT graphics card. The unnamed single-slot, full-coverage water block covers the entire length of the AMD-reference PCB for the RX 5700-series, and appears to feature an metal or POM acetal top that's been molded along the lines of the reference air cooler. A metallic "Radeon" logo dominates the front-face of the block. The company didn't reveal details such as whether the block has RGB LED embellishments. It didn't mention a launch date, either.

Custom Radeon RX 5700-series Only by Mid-August: AMD

In our reviews of the Radeon RX 5700 XT and RX 5700, we observed that while AMD made leaps with performance/Watt, the cards felt let down by the archaic lateral-blower cooling solution that hit up to 43 dBA at load, and with temperatures of the RX 5700 XT GPU reaching up to 92°C - unacceptable for a GPU that only draws 220 W. The reference cooler of the RX 5700 also exhibited some very strange fan-speed behavior at high temperatures. Much of our praise for the RX 5700-series was conditional to the hope that add-in-board (AIB) partners will innovate good cooling solutions that are quiet and keep the GPU cool. We have these custom-design graphics cards based on the two GPUs to look forward to, but according to a Reddit post by Scott Herkelman, who leads the Radeon brand at AMD, we might have to wait a little longer.

Herkelman stated that custom-design graphics cards based on the Radeon RX 5700 XT and RX 5700 will start hitting the shelves only by mid-August. He added that he is working with his team to get many of these custom-design cards in the hands of reviewers before that, so consumers have review data ahead of availability. He also acknowledged that the reference cooling solution is the biggest drawback of the reference design, and that he "liked the idea" of providing reference-design cards with dual-fan or triple-fan axial flow reference cooling solutions similar what NVIDIA provides with its Founders Edition cards.

AMD Radeon RX 5700 "Navi" Graphics Cards Lack CrossFire Support

In a comical turn of events, while NVIDIA restored NVLink SLI support for its RTX 2070 Super graphics card on virtue of being based on the "TU104" silicon, AMD did the opposite with "Navi." The Radeon RX 5700 XT and RX 5700 lack support for AMD CrossFire. If you put two of these cards on, say, a swanky X570 motherboard that splits PCIe gen 4.0 to two x8 slots with bandwidths comparable to PCIe gen 3.0 x16; you won't see an option to enable CrossFire. AMD, responding to our question on CrossFire compatibility clarified that AMD dropped CrossFire support for "Navi" in favor of DirectX 12 and Vulkan "explicit" multi-GPU mode. The older "implicit" multi-GPU mode - CrossFire - used by DirectX 11, DirectX 9, and OpenGL games is not supported. The AMD statement follows.
Radeon RX 5700 Series GPU's support CrossFire in 'Explicit' multi-GPU mode when running a DX12 or Vulkan game that supports multiple GPU's. The older 'implicit' mode used by legacy DX9/11/OpenGL titles is not supported.

Confirmed: AMD to Cut RX 5700-series Prices at Launch

AMD in a Facebook post late Friday confirmed that its Radeon RX 5700 series graphics cards will launch at reduced prices compared to what it announced at its E3-2019 product announcement. The Radeon RX 5700 XT will have a reduced MSRP of USD $399, which puts it on par with that of the GeForce RTX 2060 Super. The Radeon RX 5700 will cost $50 less, at $349, which puts its price on par with the original RTX 2060. The commemorative limited-edition RX 5700 XT AMD 50th Anniversary Edition is now reduced to $449. AMD didn't announce any changes to the two cards' launch bundle that include a 3-month Xbox Game Pass for PC.

Commenting on the development, AMD said "We embrace competition, which drives innovation to the benefit of gamers. In that spirit, we are updating the pricing of our Radeon RX 5700 Series graphics cards, launching July 7." The company added "We know that gamers will be thrilled once they have the opportunity to experience the amazing performance, stunning visual fidelity and highly responsive gameplay these new graphics cards provide. Making history on 7/7 as the first company to launch gaming CPUs and GPUs together - the first in 7nm and PCIe 4.0 - is all about pushing the ultimate gaming experience forward for as many gamers as possible."

AMD to Slash Radeon RX 5700 "Navi" Series Prices Ahead of Launch: $399 & $349

NVIDIA attempted to torpedo the Radeon RX 5700 "Navi" series graphics card launch with the introduction of its $499 GeForce RTX 2070 Super and $399 RTX 2060 Super. AMD claimed that its upcoming Radeon RX 5700 XT outperformed the original RTX 2070, while its smaller sibling, the RX 5700 outperforms the original RTX 2060. In its E3-2019 reveal, AMD disclosed launch prices of the RX 5700 XT and the RX 5700 to be USD $449 and $379, respectively. The RTX Super launch jeopardizes this, and so, according to VideoCardz, AMD is revising its launch prices.

The Radeon RX 5700 XT now reportedly launches at just $399, while the Radeon RX 5700 is priced at $349. The RX 5700 XT is claimed to beat the original RTX 2070, while the $399 RTX 2060 Super is slower than the RTX 2070. On the other hand, the RX 5700, which was claimed to beat the $349 original RTX 2060, is now price-matched with it, unless NVIDIA comes up with price-cuts. Older reports suggested that with the advent of the RTX Super series, NVIDIA would retire the RTX 2060 and RTX 2070, after the market digests inventories left in the channel. AMD's latest move is sure to disturb that digestion.

Update Jul 6th: This has been confirmed officially by AMD here.

Various Reference Radeon RX 5700 Series Graphics Cards Pictured

AMD reference-design Radeon RX 5700 XT and RX 5700 graphics cards will launch on the 7th of July, and the company's various add-in-board (AIB) partners are ready with their inventories. VideoCardz scored pictures from various such board partners. As for the cards themselves, all of these are based on the AMD reference-design. The RX 5700 reference-design is in mass-production, contrary to older reports. All these packages appear to indicate reference clock speeds. In select markets, all of these packages include the Xbox Game Pass for PC, which gives you a 3-month access to vast library of full game titles from Microsoft.

There still are no picture leaks on custom-design Radeon RX 5700-series graphics cards, which suggests that they will be launched a little later. At Computex we spotted several new graphics card cooling solutions from AMD partners, confirming that custom-design cards are a go. The reference Radeon RX 5700 XT has an MSRP of $449, while the RX 5700 is priced at $379. As for the limited-edition Radeon RX 5700 XT AMD 50th Anniversary Edition, it will be available online through AMD.com in select markets, priced at $499. You pay the extra $50 for an exclusive product design, higher clock speeds, and likely some AMD goodies, such as an AMD|50 t-shirt.

But this time we have something a little different. Reference models of RX 5700 series and their packaging have been revealed by Twitter user momomo_us.

In this Imgur album, the reference design of Radeon RX 5700 cards along with the the retail boxes of various manufacturers like ASUS, AsRock, Yeston, Sapphire, Dataland, PowerColor and XFX, have been pictured. There is also a special box for AMD's 50th anniversary edition, which has golden accents to match the card. The regular, non anniversary edition box is designed with black and red theme to showcase regular AMD styling.

NVIDIA GeForce RTX 20 Super Market Availability Revealed

NVIDIA is giving its GeForce RTX 20-series product family a mid-cycle refresh with the RTX 20 Super-series, which sees performance uplifts across price-points, in the wake of AMD's Radeon RX 5000 "Navi" series. The company is expected to formally announce the series tomorrow (2nd July, 2019), but VideoCardz has learned the dates more relevant to you: market availability. According to them, while all three Super SKUs will be announced on July 2nd, namely the RTX 2060 Super, the RTX 2070 Super, and the RTX 2080 Super; market availability will vary.

The GeForce RTX 2060 Super and the GeForce RTX 2070 Super will be available to purchase on the 9th of July, 2019. The high-end GeForce RTX 2080 Super will be available from the 23rd of July. The RTX 2060 Super will launch at USD $399, which is on-par with the Radeon RX 5700, and $50 higher than the original RTX 2060. The RTX 2070 Super will displace the original RTX 2070 at USD $499, which could push its lower. The RTX 2080 Super will launch at USD $699, displacing the original RTX 2080. VideoCardz speculates that the original RTX 2070 and RTX 2080 (non-Ti) will attain EOL status after tomorrow's announcement. The remaining RTX 2070 and RTX 2080 units in the market will be sold at discounted prices.

NVIDIA GeForce RTX 2060 Super Smiles for the Camera

Here are some of the first live pictures (not renders) of the upcoming GeForce RTX 2060 Super graphics card. As with the rest of the RTX 20 Super-series, this card features a reference board design resembling that of the original RTX 20-series, but with a chrome embellishment that accommodates the "Super" badge. The RTX 2060 Super is designed to compete with the upcoming Radeon RX 5700 at USD $399, or $50 more than the original RTX 2060. It's based on the "TU106" silicon, and is configured with 2,176 CUDA cores, but more importantly, a memory setup that's both 33 percent larger and faster than that of the original RTX 2060, made up of 8 GB of GDDR6 memory across a 256-bit wide bus, clocked at 14 Gbps. The card is expected to perform halfway between the RTX 2060 and RTX 2070.

AMD Radeon RX 5700 XT and RX 5700 to Have Same Memory and ROP Configuration

In a bid to bolster competitiveness of the $379 Radeon RX 5700 (non-XT) against its rival from the NVIDIA camp, the GeForce RTX 2060, AMD is leaving the memory configuration completely unchanged from the faster $449 Radeon RX 5700 XT. The RX 5700 will get 8 GB of GDDR6 memory across a 256-bit wide memory bus, with the same 14 Gbps memory speed as the RX 5700 XT. This works out to a memory bandwidth of 448 GB/s. In comparison, the $349 (launch price) RTX 2060 only has 6 GB of memory, across a 192-bit wide memory bus. With a memory speed of 14 Gbps, this setup achieves 336 GB/s.

The other area where AMD is reinforcing the RX 5700 is its raster muscle. The RX 5700 has the same 64 ROPs as the RX 5700 XT. AMD carved this SKU out by disabling two workgroup processors (four RDNA compute units), reducing the stream processor count to 2,304. This also turns down the TMU count from 160 to 144. The GPU engine clock speeds are also reduced, with 1465 MHz base, 1625 MHz "gaming clocks," and 1725 MHz boost clocks; compared to 1605/1755/1905 MHz of the RX 5700 XT. The RX 5700 has a typical board power of 180W compared to the 224W of the RX 5700 XT. Custom design cards may even feature just one 8-pin PCIe power input, while some of the premium factory-overclocked designs could use 8-pin + 6-pin configurations.

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.
