Radeon RX 640 vs GeForce GTX 770 benchmarks

For gaming, the GeForce GTX 770 graphics card is better than the Radeon RX 640 in our tests.

The Radeon RX 640 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 RX 640 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.

In addition, the Radeon RX 640 has a significantly lower TDP at 50 W when compared to the GeForce GTX 770 at 230 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 770 over the Radeon RX 640.
