Radeon RX 590 vs Radeon RX 6600 XT specs and performance

According to the hardwareDB Benchmark, the Radeon RX 6600 XT GPU is faster than the Radeon RX 590 in gaming.

Our database shows that the Radeon RX 6600 XT has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the Radeon RX 6600 XT also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Furthermore, the spec sheet for both these GPUs show that 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 Radeon RX 6600 XT has a slightly lower TDP at 160 W when compared to the Radeon RX 590 at 175 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 XT over the Radeon RX 590.
