Radeon R9 390X vs Radeon RX 6700 XT comparison

In our benchmarks, the Radeon RX 6700 XT beats the Radeon R9 390X in gaming performance.

In our comparison, the Radeon RX 6700 XT 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 6700 XT also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, the Radeon RX 6700 XT has significantly more memory with 12 GiB of memory compared to 8 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 6700 XT has a slightly lower TDP at 230 W when compared to the Radeon R9 390X at 275 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6700 XT is faster than the Radeon R9 390X.
