Radeon RX 640 vs Radeon RX Vega 11 benchmarks

According to the hardwareDB Benchmark, the Radeon RX Vega 11 GPU is faster than the Radeon RX 640 in gaming.

The Radeon RX 640 has a significantly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. Despite this, the Radeon RX Vega 11 has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

In addition, the Radeon RX Vega 11 has a significantly lower TDP at 15 W when compared to the Radeon RX 640 at 50 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX Vega 11 is better than the Radeon RX 640.
