Radeon RX 7900 GRE vs Radeon RX 6700S benchmarks

In our benchmarks, the Radeon RX 7900 GRE beats the Radeon RX 6700S in gaming performance.

Next up, in terms of GPU memory, the Radeon RX 7900 GRE has significantly more memory with 16 GiB of memory compared to 8 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 6700S has a significantly lower TDP at 80 W when compared to the Radeon RX 7900 GRE at 260 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 7900 GRE over the Radeon RX 6700S.
