Radeon RX 640 vs Quadro M620 benchmarks

According to the hardwareDB Benchmark, the Radeon RX 640 GPU is faster than the Quadro M620 in gaming.

Our database shows that the Radeon RX 640 has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 640 has significantly more memory with 4 GiB of memory compared to 2 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Quadro M620 has a significantly lower TDP at 30 W when compared to the Radeon RX 640 at 50 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 640 is faster than the Quadro M620.
