Radeon R9 280 vs Radeon R9 380 benchmarks

For gaming, the Radeon R9 280 graphics card is better than the Radeon R9 380 in our tests.

The Radeon R9 380 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 380 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, the Radeon R9 380 has slightly more memory with 4 GiB of memory compared to 3 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon R9 380 has a slightly lower TDP at 190 W when compared to the Radeon R9 280 at 250 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the Radeon R9 280 is better than the Radeon R9 380.
