Radeon R9 390X vs Radeon RX 6700 specs and performance

For gaming, the Radeon RX 6700 graphics card is better than the Radeon R9 390X in our tests.

In our comparison, the Radeon RX 6700 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 6700 also has a significantly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6700 has slightly more memory with 10 GiB of memory compared to 8 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 6700 has a significantly lower TDP at 175 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 is faster than the Radeon R9 390X.
