Radeon R7 450 vs Radeon R7 M340 comparison

According to the hardwareDB Benchmark, the Radeon R7 450 GPU is faster than the Radeon R7 M340 in gaming.

In our comparison, the Radeon R7 450 has a significantly 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 the Radeon R7 M340 has significantly more memory with 4 GiB of memory compared to 2 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 450 is better than the Radeon R7 M340.
