Radeon RX 6900 XT vs Radeon RX 7800 XT specs and performance

For gaming, the Radeon RX 7800 XT graphics card is better than the Radeon RX 6900 XT in our tests.

In our comparison, the Radeon RX 6900 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. Despite this, the Radeon RX 7800 XT has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, they both have the same amount of memory at 16 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 7800 XT has a slightly lower TDP at 263 W when compared to the Radeon RX 6900 XT at 300 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the Radeon RX 7800 XT is faster than the Radeon RX 6900 XT.
