Radeon RX 580 vs Radeon RX 6650 XT comparison

According to the hardwareDB Benchmark, the Radeon RX 6650 XT GPU is faster than the Radeon RX 580 in gaming.

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.

As stated by the manufacturer, they both have the same amount of memory at 8 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 6650 XT has a slightly lower TDP at 176 W when compared to the Radeon RX 580 at 185 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 conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 6650 XT over the Radeon RX 580.
