Radeon R7 M340 vs GeForce GTX 660M benchmarks

In our benchmarks, the GeForce GTX 660M beats the Radeon R7 M340 in gaming performance.

The GeForce GTX 660M has a significantly 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. Despite this, the Radeon R7 M340 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon R7 M340 has significantly more memory with 4 GiB of memory compared to 2 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 660M over the Radeon R7 M340.
