Radeon RX 6800 vs Radeon RX 7900 GRE benchmarks

In our benchmarks, the Radeon RX 7900 GRE beats the Radeon RX 6800 in gaming performance.

Furthermore, the spec sheet for both these GPUs show that they both have the same amount of memory at 16 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 6800 has a slightly lower TDP at 250 W when compared to the Radeon RX 7900 GRE at 260 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the Radeon RX 7900 GRE is faster than the Radeon RX 6800.
