GeForce GTX 980M vs Radeon HD 7990 specs and performance

According to the hardwareDB Benchmark, the Radeon HD 7990 GPU is faster than the GeForce GTX 980M in gaming.

In our comparison, the GeForce GTX 980M 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 GeForce GTX 980M 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.

Next up, in terms of GPU memory, the GeForce GTX 980M has slightly more memory with 4 GiB of memory compared to 3 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the GeForce GTX 980M has a significantly lower TDP at 100 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.

According to the results of the hardwareDB benchmark utility, the Radeon HD 7990 is faster than the GeForce GTX 980M.
