Radeon RX 6600 XT vs GeForce RTX 5090 comparison

In our benchmarks, the GeForce RTX 5090 beats the Radeon RX 6600 XT in gaming performance.

In our comparison, the GeForce RTX 5090 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 Radeon RX 6600 XT has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, the GeForce RTX 5090 has significantly more memory with 32 GiB of memory compared to 8 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 6600 XT has a significantly lower TDP at 160 W when compared to the GeForce RTX 5090 at 575 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the GeForce RTX 5090 is faster than the Radeon RX 6600 XT.
