Radeon Vega 8 vs Quadro K620 specs and performance

For gaming, the Radeon Vega 8 graphics card is better than the Quadro K620 in our tests.

In our comparison, the Quadro K620 has a significantly 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. 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, both the Radeon Vega 8 and the Quadro K620 have an identical TDP. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon Vega 8 over the Quadro K620.
