Sapphire Radeon RX 7900 GRE Performance, Power Analysis & Noise Output

The Sapphire Radeon RX 7900 GRE uses a GPU that is not new, since it was launched in July 2023 in China. AMD decided to ship it worldwide now, at a starting price of $550 to cope with NVIDIA’s RTX 4070, whose price was recently cut, with the introduction of the RTX 4070 Super. 

The fun part of the RX 7900 GRE is that it is not a new product since it was launched in the Chinese market last year. AMD decided to offer it worldwide because of the price cut in the NVIDIA RTX 4070 once its super variant was launched.  It uses a variant of AMD’s Navi 31 GPU, which uses the RDNA 3 architecture, and its starting price is 550 dollars, addressing the mid-gaming section.

Compared to the RX 7800 XT, the 7900 GRE has the same VRAM and about $50 increased price, but it also has more computing units (CUs), 80 vs 60, and more ROPs. It uses a cost-effective version of the high-end Navi 31 GPU, which only supports 256-bit memory interface bandwidth; this is why the card comes with 16 GB of VRAM. The TDP is also lower at 260W. Compared to the line flagship, the RX 7900 XTX, the RX 7900 GRE has 80 CUs instead of 90 and 160 ROPs instead of 192. Moreover, the Infinity Cache size is half. Compared to the 7900 XT, the GRU variant has fewer CUs (80 instead of 84), fewer ROPs (160 vs. 192), and shorter memory bandwidth (256-bit vs. 320-bit). Its Infinity Cache is also smaller (64 MB vs. 80 MB).

The RX 7900 GRE focuses mostly in strong 1440p gaming performance, and in some not so demanding titles you can even increase the resolution to 4K.
