Radeon R9 270 vs Radeon R9 390 comparison

In our benchmarks, the Radeon R9 390 beats the Radeon R9 270 in gaming performance.

The Radeon R9 390 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 Radeon R9 390 also has a slightly 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 R9 390 has significantly more memory with 8 GiB of memory compared to 2 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon R9 270 has a significantly lower TDP at 150 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 Radeon R9 390 is faster than the Radeon R9 270.
