Radeon R9 390 vs TITAN Xp benchmarks

For gaming, the TITAN Xp graphics card is better than the Radeon R9 390 in our tests.

The TITAN Xp 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. In addition, the TITAN Xp also has a significantly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

Furthermore, the spec sheet for both these GPUs show that the TITAN Xp has significantly more memory with 12 GiB of memory compared to 8 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the TITAN Xp has a slightly lower TDP at 250 W when compared to the Radeon R9 390 at 275 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the TITAN Xp is faster than the Radeon R9 390.
