Several Radeon RX 7000-series graphics cards that have not been officially announced by AMD are listed in ROCm 5.6.
Despite the absence of any official announcement from AMD regarding a new Radeon RX 7000 GPU using the RDNA 3 graphics architecture, recent developments on Github have revealed some potentially upcoming GPUs. A member of the AMD subreddit spotted several GPUs listed in a pull request, as shared by u/cherryteastain. The list of these cards is provided below.
- Radeon RX 7950 XTX RDNA3 gfx1100 (Navi 31)
- Radeon RX 7950 XT RDNA3 gfx1100 (Navi 31)
- Radeon RX 7900 XT| RDNA3 gfx1100 (Navi 31)
- Radeon RX 7900 XT RDNA3 gfx1100 (Navi 31)
- Radeon RX 7800 XT RDNA3 gfx1101 (Navi 32)
- Radeon RX 7700 XT RDNA3 gfx1102 (Navi 33)
- Radeon RX 7600 XT RDNA3 gfx1102 (Navi 33)
- Radeon RX 7500 XT RDNA3 gfx1102 (Navi 33)

AMD’s lineup of RDNA 3 GPUs revolves around three primary chips: Navi 31, Navi 32, and Navi 33. Plum Bonito is the codename for the Navi 31 GPU, which bears the “GFX1100” designation. The Navi 32 GPUs are referred to as “GFX1101” and codenamed Wheat Nas, while Hotpink Bonefish is the codename for the Navi 33 GPUs that carry the “GFX1102” designation. Additionally, AMD is also developing a GFX1103 design that caters to integrated IPs like APUs.
AMD’s recent ROCm 5.6 pull includes several listings for Radeon RX 7000 RDNA 3 GPUs, although it’s unclear whether they are placeholders or actual upcoming products. However, given that these GPUs are listed alongside their corresponding RDNA 3 GFX IPs, it’s possible to make educated guesses about AMD’s plans for this lineup. If previous rumors are to be believed, the Navi 31 core architecture may be reused for a high-end Radeon RX 7950 series refresh, while the Radeon RX 7800 XT will be the sole Navi 32 chip available.
Although AMD has acknowledged that they possess the necessary resources to develop a high-end RDNA 3 graphics card that could potentially rival the NVIDIA GeForce RTX 4090, the company had no plans to release such a card due to cost and power limitations. However, there is speculation that this may change with the upcoming RDNA 3 refresh, which could include the RX 7950 XTX and 7950 XT. It’s worth noting that the Navi 31 has already achieved peak core count, so any potential refresh may focus on upgrades such as higher clock speeds, faster memory, and greater power, similar to the RX 6950 XT.
