GeForce GTX 660 vs Radeon HD 8950 specs and performance

For gaming, the GeForce GTX 660 graphics card is better than the Radeon HD 8950 in our tests.

The GeForce GTX 660 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.

Furthermore, the spec sheet for both these GPUs show that they both have the same amount of memory at 3 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the GeForce GTX 660 has a significantly lower TDP at 140 W when compared to the Radeon HD 8950 at 225 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 GeForce GTX 660 over the Radeon HD 8950.
