Radeon R9 270 vs Radeon RX 6600 comparison

For gaming, the Radeon RX 6600 graphics card is better than the Radeon R9 270 in our tests.

Our database shows that the Radeon RX 6600 has a significantly 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 also has a significantly 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 Radeon RX 6600 has significantly more memory with 8 GiB of memory compared to 2 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 6600 has a slightly lower TDP at 132 W when compared to the Radeon R9 270 at 150 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 6600 is better than the Radeon R9 270.
