Radeon RX 6600 vs Quadro K620 comparison

In our benchmarks, the Radeon RX 6600 beats the Quadro K620 in gaming performance.

Our database shows that the Radeon RX 6600 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. In addition, the Radeon RX 6600 also 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6600 has significantly more memory with 8 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 addition, the Quadro K620 has a significantly lower TDP at 45 W when compared to the Radeon RX 6600 at 132 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 6600 over the Quadro K620.
