Quadro RTX 4000 vs Radeon RX 6650 XT comparison

For gaming, the Radeon RX 6650 XT graphics card is better than the Quadro RTX 4000 in our tests.

In our comparison, the Radeon RX 6650 XT 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 6650 XT 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.

Next up, in terms of GPU memory, they both have the same amount of memory at 8 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Quadro RTX 4000 has a slightly lower TDP at 160 W when compared to the Radeon RX 6650 XT at 176 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 Radeon RX 6650 XT is better than the Quadro RTX 4000.
