Radeon RX 7900 XT vs Radeon RX 7800 XT comparison

For gaming, the Radeon RX 7900 XT graphics card is better than the Radeon RX 7800 XT in our tests.

Our database shows that both the Radeon RX 7900 XT and Radeon RX 7800 XT both have the same core clock speed. 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.

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. 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 7800 XT has a slightly lower TDP at 263 W when compared to the Radeon RX 7900 XT at 315 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 7900 XT is faster than the Radeon RX 7800 XT.
