ASRock, the leading global motherboard, graphics card and mini PC manufacturer, today launched the new Steel Legend and Challenger series graphics cards based on the AMD Radeon RX 7900 GRE GPU. The new ASRock AMD Radeon RX 7900 GRE Series graphics cards are built on the groundbreaking AMD RDNA 3 architecture, featuring redesigned compute units, second-generation AMD Infinity Cache and ray tracing technologies, and increased AI throughput. They also feature the AMD Radiance Display Engine with support for DisplayPort 2.1, full AV1 encoding and are optimized for high-performance, high-resolution 4K/1440p gaming, streaming and content creation applications.

The new ASRock AMD Radeon RX 7900 GRE Series graphics cards are equipped with high-speed 16 GB GDDR6 memory at 18 Gbps, and are pre-overclocked to deliver higher levels of performance. In addition, the AMD Radiance Display Engine provides 12 bit-per-channel color for up to 68 billion colors for incredible color accuracy. ASRock AMD Radeon RX 7900 GRE Series graphics cards also support various ASRock exclusive features, including the Striped Ring/Axial Fan, Air Deflecting Fin, Ultra-fit Heatpipe, Metal Backplate, and Polychrome SYNC technology to provide great cooling efficiency, solid construction and fancy ARGB lighting effects. With these exclusive features, ASRock AMD Radeon RX 7900 GRE Series graphics cards are premium choices for 4K/2K gamers and creators.

AMD has lowered the official MSRP of the Radeon RX 7900 XT graphics card to $749, down from its launch price of $899. Its street price, as TweakTown found out, is lower still, with certain custom-design RX 7900 XT cards selling for as low as $710 on Newegg. At this price, the RX 7900 XT is set up for a major clash with certain overclocked NVIDIA GeForce RTX 4070 SUPER graphics cards, leftover inventories of the recently retired GeForce RTX 4070 Ti, and probably even looks to soak up some sales before the RTX 4070 Ti SUPER hits the scene on January 24. The cheapest RX 7900 XT is actually one of the better-appointed custom designs out there, the ASRock RX 7900 XT Phantom Gaming and XFX RX 7900 XT Merc 319, which had originally launched at prices comparable to the PowerColor Hellhound. These are followed by the PowerColor RX 7900 XT Hellhound and Sapphire RX 7900 XT Pulse OC at $720.

The Radeon RX 7900 XT is a very capable high-end GPU that AMD categorizes as capable of 4K Ultra HD gaming with settings maxed out. It's carved out from the "Navi 31" chiplet GPU, and configured with 84 RDNA3 compute units, worth 5,376 stream processors, 168 AI accelerators, 84 Ray accelerators, 336 TMUs, and 192 ROPs. The best part about this card is its memory sub-system, with 80 MB of Infinity Cache, and 20 GB of 20 Gbps GDDR6 memory across a 320-bit wide memory bus with 800 GB/s of bandwidth on tap, which should come in handy at 4K, or when using creator or AI applications.

AMD announced the new Radeon RX 7600 XT graphics card, bolstering its mid-range of 1080p class GPUs. The RX 7600 XT is designed for maxed out AAA gaming at 1080p, although it is very much possibly to play many of the titles at 1440p with fairly high settings. You can also take advantage of technologies such as FSR 3 frame generation in games that support it, AMD Fluid Motion Frames on nearly all DirectX 12 and DirectX 11 games; as well as the new expanded AMD HyperRX performance enhancement that engages a host of AMD innovations such as Radeon Super Resolution, Anti-Lag, and Radeon Boost, to achieve a target frame rate.

The Radeon RX 7600 XT is based on the same 6 nm "Navi 33" silicon, and the latest RDNA 3 graphics architecture, as the Radeon RX 7600. If you recall, the RX 7600 had maxed out all 32 CU on the silicon. To design the RX 7600 XT, AMD retained the "Navi 33," but doubled the memory size to 16 GB, and increased the clock speeds. The 16 GB of memory is deployed across the same 128-bit wide memory bus as the 8 GB is on the RX 7600. The memory speed is unchanged, too, at 18 Gbps GDDR6-effective; as is the resulting memory bandwidth, of 288 GB/s. There are two key changes—the GPU clock speeds and power limits.

ASUS over the weekend introduced the China-exclusive Radeon RX 7900 GRE TUF Gaming White graphics card. The card shares a lot in common with the other RX 7900 series TUF Gaming custom-design cards, but swaps out the gunmetal-gray cooler shroud and backplate combo for one that's matte white. The whitewash even extends to the impellers of the three Axial Tech fans. The PCB remains black, but due to the 3-D design of the shroud and backplate, is largely concealed. The card draws power from a pair of 8-pin PCIe power connectors, and uses a 14-phase VRM to condition it for the "Navi 31 XL" ASIC.

The Radeon RX 7900 GRE (golden rabbit edition) is based on a "Navi 31 XL," a unique package that combines the 5 nm graphics compute die (GCD) of "Navi 31," with the 4-MCD (memory cache die) setup of the smaller "Navi 32" package. AMD designed this primarily to drive the mobile RX 7900 series SKUs, but it found its way to the desktop platform to fill the gap between the RX 7800 XT and RX 7900 XT, and possibly undercut the GeForce RTX 4070 Ti. It is configured with 80 out of 96 available compute units on the GCD, giving it 5,120 stream processors, 160 AI accelerators, and 80 Ray accelerators, the Infinity Cache size is reduced to 64 MB, since there are only 4 MCDs, driving its 256-bit memory bus that handles 16 GB of 18 Gbps GDDR6 memory (576 GB/s bandwidth).

AMD today at Gamescom unveiled the Radeon RX 7800 XT and Radeon RX 7700 XT performance-segment graphics cards. Designed for maxed out gaming at 1440p with ray tracing, the two are designed to square off against NVIDIA's GeForce RTX 4070 series, offering competitive performance and pricing. The two are based on AMD's latest RDNA3 graphics architecture, and use the 5 nm foundry process where it matters. Both cards claim to offer not just superior performance to the specific NVIDIA RTX 40-series SKUs they're designed to compete with, but also better future-proofing, with more video memory on offer.

At the heart of the two is the new "Navi 32" GPU, AMD's second largest chip from this generation. It is a chiplet GPU, just like the "Navi 31" that powers the RX 7900 series, albeit slightly scaled down. The graphics compute die (GCD), the die with the main graphics rendering and compute machinery, is built on the 5 nm EUV foundry node. It is flanked by four memory cache dies (MCDs), each built on the 6 nm foundry node. These are the same MCDs found in the "Navi 31," but four in number instead of six, which gives the "Navi 32" a 256-bit wide GDDR6 memory interface.

AMD, in a now-deleted tweet, revealed what it is probably going to announce later today—the Radeon RX 7800 XT and RX 7700 XT desktop graphics cards. The company briefly tweeted the marketing flier for these cards, before deleting it, but not before VideoCardz saved a copy. This flier confirms the SKU names RX 7800 XT and RX 7700 XT up for launch; and gives us two images of the Made by AMD (reference design) graphics card. It appears like AMD is using a common board design for both SKUs.

The reference Radeon RX 7800 XT appears to be a slightly shrunk down version of the RX 7900 XT reference. The dual-slot card comes with two axial-flow fans instead of three on the RX 7900 XT. The card draws power from two 8-pin PCIe power connectors. Earlier this month, a leak by PowerColor spilled the beans on the RX 7800 XT being based on the "Navi 32" silicon. A chiplet-based GPU just like the "Navi 31" powering the RX 7900 series; the Navi 32 is maxed out by the RX 7800 XT, and packs 3,840 stream processors, 120 AI accelerators, 60 Ray accelerators, 64 MB of Infinity Cache memory, and a 256-bit GDDR6 memory interface, which holds 16 GB of memory on the RX 7800 XT. Specs of the RX 7700 XT remain under the wraps.

"Navi 4C" is a future high-end GPU from AMD that will likely not see the light of day, as the company is pivoting away from the high-end GPU segment with its next RDNA4 generation. For AMD to continue investing in the development of this GPU, the gaming graphics card segment should have posted better sales, especially in the high-end, which it didn't. Moore's Law is Dead scored details of what could have been a fascinating technological endeavor for AMD, in building a highly disaggregated GPU.

AMD's current "Navi 31" GPU sees a disaggregation of the main logic components of the GPU that benefit from the latest 5 nm foundry node to be located in a central Graphics Compute Die; surrounded by up to six little chiplets built on the older 6 nm foundry node, which contain segments of the GPU's Infinity Cache memory, and its memory interface—hence the name memory cache die. With "Navi 4C," AMD had intended to further disaggregate the GPU, identifying even more components on the GCD that can be spun out into chiplets; as well as breaking up the shader engines themselves into smaller self-contained chiplets (smaller dies == greater yields and lower foundry costs).

PowerColor inadvertently released the first pictures of its AMD Radeon RX 7800 XT Red Devil graphics card. These pictures confirm that the RX 7800 XT is based on a maxed out version of the "Navi 32" GPU, and not the compact "Navi 31" powering the limited edition RX 7900 GRE. The "Navi 32" is a chiplet-based GPU, just like the "Navi 31," albeit smaller. Its 5 nm GCD (graphics compute die) physically features 60 RDNA3 compute units, which work out to 3,840 stream processors, 120 AI accelerators, 60 Ray accelerators, 192 TMUs, and possibly 128 ROPs. This GCD is surrounded by four 6 nm MCDs (memory cache dies), which each has a 16 MB segment of the GPU's 64 MB Infinity Cache memory, and make up its 256-bit GDDR6 memory interface.

The specs sheet put out by PowerColor confirms that the RX 7800 XT maxes out the "Navi 32," enabling all 60 CUs, and the chip's full 256-bit memory interface, to drive 16 GB of memory. The RX 7800 XT uses 18 Gbps memory speed, and hence has 576 GB/s of memory bandwidth at its disposal. The PowerColor RX 7800 XT Red Devil has dual-BIOS, and assuming the "standard/silent" BIOS runs the card at AMD reference clock speeds, we're looking at Game clocks of 2210 MHz, and 2565 MHz boost. The Red Devil draws power from a dual 8-pin PCIe power connector set up (375 W max); the cooler is visibly smaller than the one on the company's RX 7900 series Red Devil cards. A 16+2 phase VRM powers the card. With pictures of the card out, we expect a global product launch within the next 30 days.

Here are some of the first pictures of the Sapphire Radeon RX 7900 GRE, a unique China-specific product that isn't just its own Sapphire custom-design, but also a whole different SKU. We first learned about the existence of the RX 7900 GRE earlier this month, and this would be one of its first custom design implementations. The Golden Rabbit Edition (GRE), is a limited edition SKU of the Radeon RX 7900 series. It's neither the RX 7900 XTX nor the RX 7900 XT, but positioned a notch below the latter. Based on the same "Navi 31" silicon as the two, the RX 7900 GRE is equipped with 84 CU (5,376 stream processors), or the same GCD core-configuration as the RX 7900 XT. It however, gets just 16 GB of memory, across a narrower 256-bit wide memory bus.

The Radeon RX 7900 GRE is carved out of the "Navi 31" by disabling two of the six MCDs, which reduces the Infinity Cache size to 64 MB, and the GDDR6 memory bus width to 256-bit. The 5 nm GCD is carried over from the RX 7900 XT—you get 5,376 stream processors, 168 AI accelerators, 84 Ray accelerators, 336 TMUs, and 192 ROPs. It is possible that the Sapphire RX 7900 GRE uses a variation of the company's NITRO+ cooling solution that's similar to the NITRO+ Lite SKUs available in markets outside China. The key difference here is that the cooler lacks a vapor-chamber plate, and instead uses a solid copper base-plate to pull heat from the GPU and memory. AMD needs to fill the vast gap in its product stack between the $250 RX 7600 and the $700+ RX 7900 XT, and SKUs such as the RX 7900 GRE could help it compete better against the likes of the RTX 4070 Ti in competitive markets such as China.

AMD is planning to plug the Atlantic gap between its mainstream Radeon RX 7600 and enthusiast-class RX 7900 XT with the RX 7800 series and RX 7700 series, with either an announcement or teaser planned for 2023 Gamescom, which is scheduled for August. There could be up to four new graphics card SKUs announced, with their product launches spread across Q3 and Q4 2023. The "Navi 32" MCM is expected to power at least three of these SKUs, while it was recently rumored that AMD could design a new GPU that has the GCD of the "Navi 31" on the package of "Navi 32" with its four MCDs, to end up with a higher CU count than what the "Navi 32" can offer.

The "Navi 32" GPU is an MCM, just like the "Navi 31" powering the RX 7900 series. It is rumored to feature a 5 nm GCD (graphics compute die) with 60 RDNA3 compute units, which work out to 3,840 stream processors, 120 AI accelerators, 60 Ray Accelerators, 240 TMUs, and possibly 128 ROPs. The four 6 nm MCDs give it 64 MB of Infinity Cache, and a 256-bit wide GDDR6 memory interface. Assuming the RX 7800 XT uses the unnamed new MCM with the GCD of the "Navi 31" that has a CU count somewhere between 60 and 72, a maxed-out "Navi 32" could power the RX 7800, while its cut-down variants power the RX 7700 XT and RX 7700.

AMD Radeon RX 7800 XT will be a much-needed performance-segment addition to the company's Radeon RX 7000-series, which has a massive performance gap between the enthusiast-class RX 7900 series, and the mainstream RX 7600. A report by "Moore's Law is Dead" makes a sensational claim that it is based on a whole new ASIC that's neither the "Navi 31" powering the RX 7900 series, nor the "Navi 32" designed for lower performance tiers, but something in between. This GPU will be AMD's answer to the "AD103." Apparently, the GPU features the same exact 350 mm² graphics compute die (GCD) as the "Navi 31," but on a smaller package resembling that of the "Navi 32." This large GCD is surrounded by four MCDs (memory cache dies), which amount to a 256-bit wide GDDR6 memory interface, and 64 MB of 2nd Gen Infinity Cache memory.

The GCD physically features 96 RDNA3 compute units, but AMD's product managers now have the ability to give the RX 7800 XT a much higher CU count than that of the "Navi 32," while being lower than that of the RX 7900 XT (which is configured with 84). It's rumored that the smaller "Navi 32" GCD tops out at 60 CU (3,840 stream processors), so the new ASIC will enable the RX 7800 XT to have a CU count anywhere between 60 to 84. The resulting RX 7800 XT could have an ASIC with a lower manufacturing cost than that of a theoretical Navi 31 with two disabled MCDs (>60 mm² of wasted 6 nm dies), and even if it ends up performing within 10% of the RX 7900 XT (and matching the GeForce RTX 4070 Ti in the process), it would do so with better pricing headroom. The same ASIC could even power mobile RX 7900 series, where the smaller package and narrower memory bus will conserve precious PCB footprint.

Chips and Cheese published their very in-depth review of AMD's Radeon RX 7600 GPU last weekend - a team member (Jiray) took it upon themselves to actually buy the card, since a sample unit was not supplied for evaluation. The site's exploration of this graphics processing unit on an architectural level revealed a couple of positive aspects - which comes as a minor surprise since the Radeon RX 7600 received a generally lukewarm reception upon launch at the end of last month. Thanks to the Radeon RX 7600's Navi 33 XL GPU being a monolithic chip it seems to outpace—in terms of cache and memory latency performance—chiplet-based designs as featured in the vastly more powerful (and expensive) Radeon RX 7900-series cards.

Factoring in the smaller space that the RDNA 3 Navi 33 die occupies - it seems that it gains an advantage over the flagship card. Chips and Cheese reports that AMD's RX 7900 XTX takes up to 58% longer to access and pull data from its pool of Infinity Cache, when contrasted with the recently released sibling. The RX 7600 GPU exhibits 15% lower VRAM latencies compared to the RX 7900 XTX when retrieving data from the onboard GDDR6 VRAM chiplets. The review points to a greater disparity between current high-end and mid-range cards when looking back at equivalent models from the preceding generation: "The difference is especially large with RDNA 3. With RDNA 2, the RX 6900 XT had 151.57 ns of Infinity Cache latency compared to 130 ns on the RX 6600 XT, or a 16.5% latency penalty for the larger GPU." Chips and Cheese reckons that AMD's Navi 31's "chiplet configuration may be causing higher latency."

ASRock, the leading global motherboard, graphics card and mini PC manufacturer, today launched the new Phantom Gaming, Steel Legend and Challenger series graphics cards based on the new AMD Radeon RX 7600 GPUs. In addition to the popular Phantom Gaming and Challenger models, the new Steel Legend series graphics cards are designed in white with eye-catching snow camouflage elements and fancy ARGB lighting effects that support Polychrome SYNC technology, providing more premium choices for consumers who want to assemble white-themed PC builds.

The new ASRock AMD Radeon RX 7600 Series graphics cards are built on the groundbreaking AMD RDNA 3 architecture, featuring up to 32 redesigned compute units and second-generation AMD Infinity Cache technology. They also offer the latest features and capabilities including AMD Radiance Display Engine, full AV1 encoding and more to power high-performance 1080p gaming, streaming and content creation applications. The new ASRock AMD Radeon RX 7600 Series graphics cards are equipped with high-speed 8 GB GDDR6 memory at 18 Gbps and are pre-overclocked to deliver higher levels of performance. The AMD Radiance Display Engine provides 12 bit-per-channel color for up to 68 billion colors for incredible color accuracy.

AMD today announced its Radeon RX 7600 graphics card, which competes against NVIDIA's upcoming RTX 4060, and succeeds the RX 6600. This GPU is based on the RDNA3 graphics architecture, but the "Navi 33" monolithic silicon it's based on, is built on the older 6 nm foundry node. The card has a total board power of 169 W, and draws power from a single 8-pin PCIe power connector. The RX 7600 maxes out this silicon, enabling all 2,048 stream processors, 64 AI Accelerators, 32 Ray Accelerators, 128 TMUs, and 64 ROPs. It offers 8 GB of memory, but using faster 18 Gbps memory chips, while the memory bus width remains 128-bit. The GPU comes with 32 MB of 2nd generation Infinity Cache memory. AMD is targeting the 1080p AAA gaming crowed with the RX 7600, with a starting price of USD $269.

Possible specifications of the upcoming AMD Radeon RX 7600 graphics card leaked to the web. At this point we don't know if the RX 7600 maxes out the silicon it is based on (with room for a faster RX 7600 XT). The leak appears to be from marketing materials of the RX 7600. It speaks of 32 Compute Units. This works out to the same 2,048 stream processors as the previous-generation RX 6600 XT, but an increase from the 1,792 of the RX 6600. The mention of AI accelerators confirms that this GPU is based on the latest RDNA3 graphics architecture.

The other RDNA3 feature referenced is the Radiance Display Engine, which supports the latest DisplayPort 2.1 and HDMI 2.1a outputs, along with 12 bpc color, and support for resolutions as high as 4K 180 Hz with a single cable. Apparently, the GPU that the RX 7600 is based on has 32 MB of Infinity Cache memory, which is the same amount as the previous-generation "Navi 23" silicon powering the RX 6600 series. For the flagship "Navi 31," the Infinity Cache memory size is generationally reduced to 96 MB (from 128 MB on "Navi 21,") because the memory bus width has generationally increased to 384-bit (from 256-bit). This could mean that the RX 7600 has a 128-bit wide memory bus, given that its Infinity Cache size is unchanged from that of the RX 6600 series.

VideoCardz has today received a tip-off from an anonymous source about a batch of Sapphire Radeon RX 7600 PULSE graphics cards - boxed products have been photographed sitting in a hardware store located "somewhere" in Asia. It is not immediately clear whether the Sapphire cards were pictured in a store-front setting, or an employee has taken a snap of stock stored in a backroom and shared it with their internet buddies. Previous leaks relating to AMD Radeon RX 7600 and 7600 XT cards have pointed to a May 25 launch day - so today's tip indicates that products have been readied well in advance of the anticipated release window.

The insider source claims that the Sapphire Radeon RX 7600 PULSE graphics card will be sold for about $249 in that particular territory. Specifications on the outer packaging can be read (if you zoom in enough) - the Pulse custom variant is labeled as being overclocked out-of-the-box, so it is highly likely that it will be fitted with a custom cooling solution. The packaging's blurb lists the presence of 32 RDNA3 CUs - indicating a full configuration of AMD's Navi 33 GPU die, consisting of 2048 stream processors. The Pulse card gets an Infinity Cache allocation of 32 MB, and a specification of (now typical) 8 GB GDDR6 video memory is confirmed.

AMD possibly has a straightforward path to increasing the performance of the "Navi 31" RDNA3 GPU to power future high-end SKUs, according to semiconductor engineer Tom Wassick. The GPU's main SIMD machinery is located in the Graphics Compute Die (GCD) built on the 5 nm EUV foundry process, surrounded by six Memory Cache Dies (MCDs) built on 6 nm, which each contain GDDR6 memory controllers, and a 16 MB segment of the GPU's 96 MB Infinity Cache memory.

In microscopic observations, Wassick noticed structures on the MCD which he thinks look like an array of through-silicon vias (TSVs), of the kind used in "Zen 3" and "Zen 4" CCDs, to wire out stacked 3D Vertical Cache memory on the L3D (L3 cache die). If the theory holds up, it could be possible for AMD to increase the L3 cache segment size per MCD from 16 MB, and the GPU's overall Infinity Cache memory size. With its RDNA2 graphics architecture (RX 6000 series), AMD significantly enlarged on-die caches on its GPUs, particularly the last-level L3 cache, even giving them the special branding of "Infinity Cache," claiming that they had a big impact in lubricating the memory sub-system, letting GPUs with 256-bit memory buses compete with NVIDIA GPUs with wider 320-bit to 384-bit interfaces.

GIGABYTE TECHNOLOGY Co. Ltd, a leading manufacturer of premium gaming hardware, today announced the new AMD Radeon RX 7900 Series graphics cards powered by the high-performance, energy-efficient AMD RDNA 3 architecture - the AORUS Radeon RX 7900 XTX ELITE 24G, Radeon RX 7900 XTX GAMING OC 24G, Radeon RX 7900 XTX 24G, Radeon RX 7900 XT GAMING OC 20G and Radeon RX 7900 XT 20G graphics cards. The new graphics cards will be available for purchase on December 13, 2022.

The new graphics cards are the world's first gaming graphics cards to feature an advanced AMD chiplet design, delivering exceptional performance and superb energy efficiency to power high-framerate 4K and higher resolution gaming in the most demanding titles.

ASRock, the leading global motherboard, graphics card and mini PC manufacturer, today launched the new AQUA, Taichi and Phantom Gaming series graphics cards based on AMD Radeon RX 7900 Series GPUs.

The new graphics cards are built on the groundbreaking AMD RDNA 3 architecture with chiplet technology. AMD RDNA 3 architecture delivers up to 54% more performance per watt than AMD RDNA 2, features the world's fastest interconnect linking the graphics and memory system chiplets at up to 5.3 TB/s, and offers up to 96 new unified compute units and second-generation AMD Infinity Cache technology. It also delivers increased AI throughput that provides up to 2.7X higher AI performance, and rearchitected compute units with second-generation ray tracing technology that provides up to 1.8X higher ray tracing architectural performance in select titles versus AMD RDNA 2 architecture.

AMD in its technical presentation confirmed the reference clock speeds of the Radeon RX 7900 XTX and RX 7900 XT RDNA3 graphics cards. The company also made its first reference to a GeForce RTX 40-series "Ada" product, the RTX 4080 (16 GB), which is going to launch later today. The RX 7900 XTX maxes out the "Navi 31" silicon, featuring all 96 RDNA3 compute units or 6,144 stream processors; while the RX 7900 XT is configured with 84 compute units, or 5,376 stream processors. The two cards also differ with memory configuration. While the RX 7900 XTX gets 24 GB of 20 Gbps GDDR6 across a 384-bit memory interface (960 GB/s); the RX 7900 XT gets 20 GB of 20 Gbps GDDR6 across 320-bit (800 GB/s).

The RX 7900 XTX comes with a Game Clocks frequency of 2300 MHz, and 2500 MHz boost clocks, whereas the RX 7900 XT comes with 2000 MHz Game Clocks, and 2400 MHz boost clocks. The Game Clocks frequency is more relevant between the two. AMD achieves 20 GB memory on the RX 7900 XT by using ten 16 Gbit GDDR6 memory chips across a 320-bit wide memory bus created by disabling one of the six 64-bit MCDs, which also subtracts 16 MB from the GPU's 96 MB Infinity Cache memory, leaving the RX 7900 XT with 80 MB of it. The slide describing the specs of the two cards compares them to the GeForce RTX 4080, which is what the two could compete more against, especially given their pricing. The RX 7900 XTX is 16% cheaper than the RTX 4080, and the RX 7900 XT is 25% cheaper.

AMD, in its technical presentation for the new Radeon RX 7900 series "Navi 31" GPU, gave us an elaborate explanation on why it had to take the chiplets route for high-end GPUs, devices that are far more complex than CPUs. The company also enlightened us on what sets chiplet-based packages apart from classic multi-chip modules (MCMs). An MCM is a package that consists of multiple independent devices sharing a fiberglass substrate.

An example of an MCM would be a mobile Intel Core processor, in which the CPU die and the PCH die share a substrate. Here, the CPU and the PCH are independent pieces of silicon that can otherwise exist on their own packages (as they do on the desktop platform), but have been paired together on a single substrate to minimize PCB footprint, which is precious on a mobile platform. A chiplet-based device is one where a substrate is made up of multiple dies that cannot otherwise independently exist on their own packages without an impact on inter-die bandwidth or latency. They are essentially what should have been components on a monolithic die, but disintegrated into separate dies built on different semiconductor foundry nodes, with a purely cost-driven motive.

AMD today announced the Radeon RX 7900 XTX and Radeon RX 7900 XT gaming graphics cards debuting its next-generation RDNA3 graphics architecture. The two new cards come at $999 and $899—basically targeting the $1000 high-end premium price point.Both cards will be available on December 13th, not only the AMD reference design, which is sold through AMD.com, but also custom-design variants from the many board partners on the same day. AIBs are expected to announce their products in the coming weeks.The RX 7900 XTX is priced at USD $999, and the RX 7900 XT is $899, which is a surprisingly small difference of only $100, for a performance difference that will certainly be larger, probably in the 20% range. Both Radeon RX 7900 XTX and RX 7900 XT are using the PCI-Express 4.0 interface, Gen 5 is not supported with this generation. The RX 7900 XTX has a typical board power of 355 W, or about 95 W less than that of the GeForce RTX 4090. The reference-design RX 7900 XTX uses conventional 8-pin PCIe power connectors, as would custom-design cards, when they come out. AMD's board partners will create units with three 8-pin power connectors, for higher out of the box performance and better OC potential. The decision to not use the 16-pin power connector that NVIDIA uses was made "well over a year ago", mostly because of cost, complexity and the fact that these Radeons don't require that much power anyway.
