Radeon RX 640 vs Radeon Vega 8 comparison

According to the hardwareDB Benchmark, the Radeon RX 640 GPU is faster than the Radeon Vega 8 in gaming.

Our database shows that 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 Vega 8 has a significantly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

In addition, the Radeon Vega 8 has a slightly lower TDP at 45 W when compared to the Radeon RX 640 at 50 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 640 is faster than the Radeon Vega 8.
