We have been commenting for a few days now that the launch of the Radeon RX 7900 XT and Radeon RX 7900 XTX is controversial, not only because it did not live up to the expectations created, but also because more and more voices are talking about problems at the architecture level which could not be solved by pulling the drivers.

AMD came out saying that everything is fine and that these problems do not exist because they affect “experimental features”, but today we have new information that completely contradicts AMD and that indicates that something is definitely wrong.

3DC Center she was able to confirm with her own tests that the implementation of mesh shaders in Radeon RX 7900 XT and Radeon RX 7900 XTX He has problemsbecause as we can see in the attached graph, both graphics cards have less than half the performance of Radeon RX 6800 XT in 3DMark Mesh Shader.

it seems to exist something is wrong with the new generation of AMD graphics, and it cannot be a coincidence that there are still no custom Radeon RX 7900 XT or Radeon RX 7900 XTX in stores from GIGABYTE, MSI and ASUS level assemblers. MSI has confirmed that they will launch their own models in the first quarter of 2023, which is quite a long way from the launch of the reference models and something that only confirms what I told you earlier.

Perhaps these assemblers preferred to wait for AMD to have more mature Navi 31 graphics cores available than the current ones, which are based on the A0 revision, although this question is in some controversy, since according to various sources AMD used said revisions in other graphics solutions, such as Radeon RX 5000 and RX 6000, and does not indicate an “early” or “unfinished” chip.

We’ll see how this whole controversy plays out and what happens when personalized models from different assembly companies hit the market. It will be interesting see which revision of the Navi 31 GPU they are usingY repeat the tests again focused on assessing not only how mesh shaders work, but also others that delve into issues that have been controversial, such as power profile management.

Overall, I want to point out that Radeon RX 7900 XT and Radeon RX 7900 XTX swith competing products, especially in the raster, and it must be acknowledged that AMD has been able to improve a lot in ray tracing. We’ll see if we’re soon surprised by FSR3 supported by AI that’s at DLSS level.
