Radeon RX 640 vs Quadro RTX 4000 benchmarks

In our benchmarks, the Quadro RTX 4000 beats the Radeon RX 640 in gaming performance.

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. Despite this, the Quadro RTX 4000 has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Next up, in terms of GPU memory, the Quadro RTX 4000 has significantly more memory with 8 GiB of memory compared to 4 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 Radeon RX 640 has a significantly lower TDP at 50 W when compared to the Quadro RTX 4000 at 160 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In terms of raw gaming performance in our GPU benchmark, the Quadro RTX 4000 is better than the Radeon RX 640.
