Radeon R9 280 vs GeForce GTX 770M specs and performance

In our benchmarks, the Radeon R9 280 beats the GeForce GTX 770M in gaming performance.

The Radeon R9 280 has a slightly 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 R9 280 also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

As stated by the manufacturer, they both have the same amount of memory at 3 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GTX 770M has a significantly lower TDP at 75 W when compared to the Radeon R9 280 at 250 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In terms of raw gaming performance in our GPU benchmark, the Radeon R9 280 is better than the GeForce GTX 770M.
