The RX 6950XT/7900GRE build also included an AMD Ryzen 7 7800X3D processor and DDR5 6000 MHz CL36 RAM. So, in the game Avatar: Frontier of Pandora with Ultra graphics and DX12, the average FPS difference between the RX 6950XT and 7900GRE was only 1-2 fps in favor of the latter. On average, across all 13 games at 2.4GHz, the RX 7900GRE was only 6.4% faster than the 6950XT (and sometimes consumed even more power). If we exclude Last Epoch, the difference is 8.7%.
The RX 6800 and 7800 XT are even more similar than the RX 6950XT and 7900GRE. The configuration with them was the same as above. In Starfield with the ultra overclocking preset, the 7800 XT was already 20% faster than the RX 6800, and was also 19% faster at 2.2GHz. In Last Epoch, the 7800 XT was 12% better than the 6800 at 2.2GHz; In Resident Evil 4 it was 20% faster overclocking and 16% faster at 2.2GHz; PUBG Battlegrounds was 16% faster at 2.2GHz and 19% faster overclocking. Fortnite is 12% faster at 2.2GHz and 16% faster overclocked.
The RX 6650XT and 7600 are almost identical in terms of video memory frequencies and other features. In the game Avatar: Frontier of Pandora with a high preset, both models turned out to be as close as possible in terms of performance, and the overclocking result was generally the same. Last Epoch game came with ultra preset and DX11; Here at 2.4GHz the RX 7600 was 15% faster than the RX 6650XT and 11% faster overclocking. With the Ultra preset and DX11E, we managed to get 11% more FPS at 2.4 Hz and 5% more FPS when overclocked in PUBG Battlegrounds compared to the 6650XT with the 7600. In Fortnite, the 7600 had a 13.3% advantage at 2.4Hz, but only a 6% advantage in overclocking.

The RX 6650 XT and 7600 had roughly the same results as the RX 6800 and 7800 XT. In some scenarios, the 7600’s power was limited compared to the RX 6650 XT. When both models were at the limit of their power, the difference between them was greater than when overclocking. This is because the RX 6650 XT always maintains one frequency, whereas the 7600 has to be throttled to stay within 200W in some games.
In most scenarios, at the same 2.4GHz clock speed, the RX 6950 XT and the 7900GRE will consume roughly the same amount of power. However, if you increase these frequencies to the maximum, the power consumption of the RX 6950 XT will be slightly higher: around 350 W versus 300-340 W for the 7900GRE.
Also overall the results show that if you take the 7800 XT and the 7600 the RDNA3 is generally better and faster at the same frequency. As for the 7900GRE, there are new games where it will give more advantages and higher FPS.
