Massive AMD Radeon RX 7000 series information dump reveals potential SKUs, hardware specifications, and launch date

As we move closer to the launch of the next-gen AMD Radeon RX 7000 series graphics card, the frequency and the depth of the leaks keeps on increasing. Paul from RedGamingTech has now leaked the entire SKU list of the AMD Radeon RX 7000 boards based on the RDNA 3 architecture. All of the different SKUs are reportedly based around three GPUs, the flagship Navi 31, the high-end/midrange Navi 32, and the midrange/low-end Navi 31.

AMD Radeon RX 7000 SKUs

Based on the Navi 31 GPU, we have the RX 7975 XT, the RX 7950 XT, and the RX 7900 XT. The RX 7975 XT is supposedly the full implementation of the Navi 31 with 96 Compute Units (CUs), a 384-bit wide memory bus, and 24 GB of memory. The RX 7950 XT will reduce the number of CUs to 88 while packing the same memory size, and bus width. Compared to its bigger brothers, the RX 7900 XT will see a spec reduction in all aspects with 80 CUs, a 320-bit wide bus, and 20 GB of VRAM.

The high-end/midrange RDNA 3 SKUs reportedly use the Navi 32 GPU and include the RX 7800 XT, the RX 7800, and the RX 7700 XT. The RX 7800 XT will feature 64 CUs, a 256-bit wide bus, and 16 GB of VRAM. The RX 7800 will allegedly cut the CU count to 56 while running on a 256/192-bit bus and 16/12 GB of memory. The RX 7700 XT will end up with 48 CUs and 12 GB of VRAM over a 192-bit wide memory bus.

AMD is planning to outfit the midrange/low-end RX 7000 cards with the Navi 33 GPU. The top two SKUs in this category, the RX 7600 XT and the RX 7600, will reportedly employ 40 and 32 CUs respectively and come with 8 GB of memory over a 128-bit bus. The low-end RX 7500 XT will reportedly feature 20 CUs, a comparatively narrow 96-bit bus, and 6 GB of RAM.

That said, Paul is not sure about the RAM configuration of the RX 7800 and the RX 7500 XT. So, take the figures presented here as pure conjecture.

Infinity Cache and 3D V-Cache

As far as the Infinity Cache is concerned, Paul is unsure about the exact amount of cache AMD is planning to use in each SKU. The leaker’s sources are also conflicted on the matter with one source alleging AMD Navi 31 will use 384 MB of Infinity Cache, while another source puts the amount at 192 MB, claiming “each SKU will have half the amount of Infinity Cache as bus width”.

Per the leaker, the presence of 3D V-Cache in RDNA 3 boards is also mired in uncertainty. One of Paul’s sources mentions that V-Cache could only be available on non-gaming professional RX 7000 cards or RDNA 4.

RDNA 3 Performance

When it comes to performance estimates, Paul thinks that the Navi 31 is 2x faster in rasterization than the Navi 21 featured in the RX 6900 XT. Apart from improvements afforded by the RDNA 3 architecture, the leaker suggests that AMD is going to clock the RX 7000 boards quite high with the frequency lying somewhere between 3 and 3.2 GHz.

Moreover, the TDP figures for reference cards can reportedly go as high as 375 W. Whereas custom AIB boards can push 450 W.

Finally, Paul claims that Radeon RX 7000 cards will launch between mid-October to November. The launch will follow the same pattern as the RX 6000 launch with the high-end Navi 31-based boards appearing earlier than the Navi 33 cards which are slated to launch in late 2022 or early 2023.
