GeForce GTX 960 vs Radeon HD 7990 benchmarks

In our benchmarks, the Radeon HD 7990 beats the GeForce GTX 960 in gaming performance.

Our database shows that the GeForce GTX 960 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 GeForce GTX 960 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 GeForce GTX 960 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 GeForce GTX 960 has a significantly lower TDP at 120 W when compared to the Radeon HD 7990 at 375 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 conclusion, all specs and GPU benchmarks considered, will recommend the Radeon HD 7990 over the GeForce GTX 960.
