Radeon RX 580 2048SP vs Radeon RX 6600M comparison

For gaming, the Radeon RX 6600M graphics card is better than the Radeon RX 580 2048SP in our tests.

The Radeon RX 6600M 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 6600M 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.

In addition, the Radeon RX 6600M has a significantly lower TDP at 100 W when compared to the Radeon RX 580 2048SP at 150 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6600M is faster than the Radeon RX 580 2048SP.
