AMD Radeon RX 7900 GRE
The GRE is just too similar to the 7800 XT in terms of performance and would really benefit from faster memory to fully leverage those extra cores. Speaking of which, memory overclocking is almost entirely restricted on the GRE, as AMD only allows the frequency to be increased by a maximum of 3% to 2,316 MHz, resulting in a throughput of 18.5 Gbps.

GPU Benchmarks
GPU benchmark scores are aggregated from dozens of tests conducted in TechSpot's labs, compiled from our full library of GPU reviews and gaming benchmarks. Scores are normalized to a shared baseline and organized by resolution, covering rasterized workloads exclusively. Ray tracing and upscaling technologies are disabled to guarantee consistent, like-for-like comparisons.
