AMD confirms Radeon RX 7900 GRE artificial overclock limit bug, promises fix

Last year, in July 2023, the Radeon RX 7900 GRE was first released exclusively for China, but since then, AMD has decided to introduce this SKU to the global DIY market. The card has been widely reviewed by outlets (including us), where many noticed the limitations when trying to overclock the GPU.

The Radeon RX 7900 GRE sits between the Radeon RX 7900 XT and the RX 7800 XT, featuring 33% more cores than the Navi-32-based 7800XT variant. However, due to power constraints, it does not perform much better than the 7800 XT, especially for reference design models or GPUs running at reference speeds.

As explained by TechPowerUP, the Radeon RX 7900 GRE cards have artificial clock limits despite the comparatively high power restrictions. The highest programmable GPU clock speed is 2803MHz, and the memory can only reach 2316MHz. However, removing the arbitrary frequency restriction should result in better performance.

AMD (via Hardware Unboxed) has acknowledged this issue and has promised to fix it. However, we don't have an exact timeline for this fix just yet.

KitGuru says: Once AMD fixes these issues, the AMD Radeon RX 7900 GRE should become a slightly better buy, especially if you like fine-tuning your graphics card to its optimal performance.
