Radeon R7 450 vs Radeon R9 M375X benchmarks

In our benchmarks, the Radeon R9 M375X beats the Radeon R7 450 in gaming performance.

The Radeon R7 450 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.

Next up, in terms of GPU memory, the Radeon R9 M375X 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.

According to the results of the hardwareDB benchmark utility, the Radeon R9 M375X is faster than the Radeon R7 450.
