Radeon R9 M375X vs Quadro K620 benchmarks

According to the hardwareDB Benchmark, the Quadro K620 GPU is faster than the Radeon R9 M375X in gaming.

The Quadro K620 has a slightly 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. In addition, the Quadro K620 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, the Radeon R9 M375X has significantly more memory with 4 GiB of memory compared to 2 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In terms of raw gaming performance in our GPU benchmark, the Quadro K620 is better than the Radeon R9 M375X.
