AMD Announces Wider Launch of Radeon RX 7900 GRE, Adjusts Pricing of RX 7700 XT

AMD today announced wider availability of the Radeon RX 7900 GRE (Golden Rabbit Edition) graphics card. The card is now available in certain western markets including in Europe and North America; although AMD wouldn't call this a global launch. The card was originally designed as a limited edition product meant for the Chinese market, and has been available there since July 2023. The decision to launch the card in other markets may have been driven by NVIDIA's January launch of the GeForce RTX 4070 SUPER and RTX 4070 Ti SUPER, which have caused cascading price cuts among the older RTX 4070, RTX 4070 Ti; and AMD's RX 7800 XT, creating a rather big gap between this card and the RX 7900 XT, which is probably why AMD decided to launch the RX 7900 GRE at $550.

AMD carved the RX 7900 GRE from the "Navi 31" silicon powering the RX 7900 series, by disabling two MCDs (instead of disabling just one on the RX 7900 XT); which results in a 256-bit memory bus, which drives 16 GB of 18 Gbps GDDR6 memory, for 576 GB/s of memory bandwidth. The GCD sees 80 out of 96 compute units (CU) being enabled, for 5,120 stream processors, 320 TMUs, 160 AI accelerators, and 80 Ray accelerators. The card is configured with 160 out of 192 ROPs present on the silicon. The total board power (TBP) is set to 260 W, which is about the same as the RX 7800 XT; but there are 33% more shaders to go around. Several AMD board partners are expected to announce their custom RX 7900 GRE cards today, with market availability slated for tomorrow, February 27, 2024. Although AMD is known to have a reference design card, it is expected to be confined to the OEM/SI channel. In addition, AMD also cut the official MSRP of the RX 7700 XT to $419.

AMD Radeon RX 7700 XT Confirmed with 192-bit Memory Bus in ASRock Regulatory Leak

AMD Radeon RX 7700 XT is confirmed to feature 12 GB as its standard memory size, and feature a 192-bit wide GDDR6 memory interface, according to a leaked regulatory filing by ASRock for its upcoming graphics cards. We already know from last week's mega leak of the PowerColor RX 7800 XT Red Devil that the card maxes out the "Navi 32" silicon, enabling all 60 RDNA3 CU, and comes with 16 GB of memory across the chip's full 256-bit memory bus. This filing suggests how AMD will carve the RX 7700 XT out.

Probably designed to compete with the GeForce RTX 4070, the RX 7700 XT is based on the same "Navi 32" silicon as the RX 7800 XT, but cut down. AMD is expected to disable some of the 60 CU physically present on the 5 nm GCD, while one of the four 6 nm MCDs will be disabled, giving the chip a 192-bit memory bus to drive its 12 GB of memory. We know from the PowerColor leak that the RX 7800 XT gets 18 Gbps memory speed. It remains to be seen if AMD sticks with this speed for even the RX 7700 XT, in which case, it gets 432 GB/s of memory bandwidth at its disposal. AMD is expected to launch the RX 7800 XT and RX 7700 XT within this quarter (before October).

PowerColor AMD Radeon RX 7800 XT Pictured, Confirmed Based on "Navi 32"

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.

AMD Radeon RX 7900 GRE ASIC Smaller than Navi 31, Slightly Larger than Navi 21

The GPU at the heart of the China-exclusive AMD Radeon RX 7900 GRE (Golden Rabbit Edition) sparked much curiosity. It is a physically different GPU from the one found in desktop Radeon RX 7900 XT and RX 7900 XTX graphics cards. AMD wouldn't go through all that effort designing a whole different GPU just for a limited edition graphics card, which means this silicon could find greater use for the company—for example, this could be the package AMD uses for its upcoming mobile RX 7900 series. AMD wouldn't go through all the effort designing a first-party MBA (made by AMD) PCB for the silicon just for the RX 7900 GRE, and so this PCB, with this particular version of the "Navi 31" silicon, could see a wider global launch, probably as the rumored Radeon RX 7800 XT, or something else (although with a different set of specs from the RX 7900 GRE).

We compared the sizes of the new "Navi 31" package found in the RX 7900 GRE, with those of the regular "Navi 31" powering the RX 7900 XT/XTX, the previous-generation "Navi 21" powering the RX 6900 XT, and the NVIDIA AD103 silicon powering the desktop GeForce RTX 4080. There are some interesting findings. The new smaller "Navi 31" package is visibly smaller than the one powering the RX 7900 XT/XTX. It is a square package, compared to the larger rectangular one, and has a significantly thinner metal reinforcement brace. What's interesting is that the 5 nm GCD is still surrounded by six 6 nm MCDs. We don't know if they've disabled two of the six MCDs, or whether they're dummies. AMD uses dummy chiplets as structural reinforcement in some of its EPYC server processors. The dummies spread some of the mounting pressure applied by the IHS or cooling solution, so the logic behind surrounding the GCD with six of these MCDs could be the same.

Sapphire Radeon RX 7900 GRE Pictured: A Unique China-specific SKU

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.
