Radeon R7 M340 vs Radeon HD 8670M benchmarks

According to the hardwareDB Benchmark, the Radeon R7 M340 GPU is faster than the Radeon HD 8670M in gaming.

The Radeon HD 8670M has a slightly 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.

Next up, in terms of GPU memory, the Radeon R7 M340 has significantly more memory with 4 GiB of memory compared to 1 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In terms of raw gaming performance in our GPU benchmark, the Radeon R7 M340 is better than the Radeon HD 8670M.
