AMD's unreleased Radeon RX 7950 XTX, 7950 XT, 7800 XT, 7700 XT, 7600 XT, & 7500 XT RDNA 3 GPUs have shown up in a ROCm 5.6 pull request.
AMD has yet to launch or announce a new Radeon RX 7000 GPU based on the RDNA 3 graphics architecture besides the Radeon RX 7900 XTX & RX 7900 XT but it looks like a recent pull request made within Github has disclosed several announced GPUs as spotted by a member of the AMD subreddit. The list of the cards is seen below (Credits: u/cherryteastain):
The AMD RDNA 3 GPU portfolio is based on three main chips, the Navi 31, Navi 32, and Navi 33. The Navi 31 GPU is designated as "GFX1100" and codenamed Plum Bonito, the Navi 32 GPUs are designated as "GFX1101" and codenamed Wheat Nas while the Nav 33 GPUs are designated as "GFX1102" and codenamed Hotpink Bonefish. There's also a GFX1103 design which is aimed at integrated IPs such as APUs.
Now these AMD Radeon RX 7000 RDNA 3 GPUs have been listed within the recent ROCm 5.6 pull and may just be placeholders but since they are also listed besides their RDNA 3 GFX IPs, we can guess what AMD is planning to do with the lineup. It looks like a possible high-end Radeon RX 7950 series refresh will reuse the Navi 31 core architecture while the Radeon RX 7800 XT will be the only Navi 32 chip on the block. This aligns with previous rumors.
AMD has pointed out that they have the resources to develop a higher-end RDNA 3 graphics card that could compete with the NVIDIA GeForce RTX 4090 but didn't plan on making such a card due to price/power constraints. We can speculate that this vision will come to form with the RDNA 3 refresh as the RX 7950 XTX and 7950 XT though Navi 31 is already being offered in its peak core count so the only other updates we can expect
