Gaming Benchmarks

You might wonder about the actual real-world differences between these processors, which is why we’ve put both these processors through rigorous testing using our test setup.

Test Bench

The setup we’ve used in this comparison puts the processor as the only point of failure in the system to give you the worst-case scenario for when your CPU becomes the limiting factor in your system. To do this, we’ve tested several games at the 1080p resolution.

Baldur’s Gate 3
