Research enthusiasts make this conclusion after analyzing the work of video cards under load and the source libraries of Mesa3D.

That would explain the GPU’s strange behavior and the unusual code snippets.

It is possible that the Radeon RX 7900 XT and RX 7900 XTX video cards use early versions of graphics chips. Research enthusiasts make this conclusion after analyzing the work of video cards under load and the source libraries of Mesa3D, developed with the participation of AMD.

First, researchers and reviewers noticed the unusually strong operating frequency spread of the Radeon RX 7900 video cards. It is assumed that the reason for the huge number of values on the Radeon RX 7900 graphics is the inability of the GPU to stably maintain the same frequency at the same voltage level.

For comparison: the second graph shows the distribution of working frequencies of GeForce RTX 4080, the third the distribution of frequencies of Radeon RX 6900 XT.

It is also claimed that in some games the Radeon RX 7900 graphics card clock rate can be much higher than in others. The energy consumption remains the same.

Another weird thing is this is a piece of code from the Mesa3D library, the OpenGL implementation and other open source graphics APIs. Judging by the sources, now on the market there are A0 revision chips, that is, preliminary (release versions begin with A1 revision) and for some reason they have the preliminary selection of shaders turned off.

Perhaps enthusiasts believe that AMD was for some reason important to release its graphics cards right now and for this the company had to ship to manufacturers early versions of GPUs containing some errors.

Remarkably, rumors of problems with the company’s new graphics cards have been circulating for weeks. Although, earlier, we were talking about the complexity of the BIOS and the drivers, not about possible hardware errors.

AMD officials have not yet responded to requests from journalists to comment on the researchers’ assumptions.
