Radeon RX 7900 XT vs Radeon RX 7900 GRE benchmarks

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

Next up, in terms of GPU memory, the Radeon RX 7900 XT has slightly more memory with 20 GiB of memory compared to 16 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 7900 GRE has a slightly lower TDP at 260 W when compared to the Radeon RX 7900 XT at 315 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

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