GeForce GTX 970M vs Radeon HD 7990 specs and performance

In our benchmarks, the Radeon HD 7990 beats the GeForce GTX 970M in gaming performance.

The Radeon HD 7990 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. Despite this, the GeForce GTX 970M 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, 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 970M has a significantly lower TDP at 75 W when compared to the Radeon HD 7990 at 375 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In terms of raw gaming performance in our GPU benchmark, the Radeon HD 7990 is better than the GeForce GTX 970M.
