Radeon RX 7900 XT vs Arc A770 comparison

For gaming, the Radeon RX 7900 XT graphics card is better than the Arc A770 in our tests.

In our comparison, the Radeon RX 7900 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 7900 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 the Radeon RX 7900 XT has slightly more memory with 20 GiB of memory compared to 16 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Arc A770 has a significantly lower TDP at 120 W when compared to the Radeon RX 7900 XT at 315 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 7900 XT is better than the Arc A770.
