On slower CPU such as i9-9980HK, the results are different.
[i9-9980HK is a lot slower than M3
Max](https://www.cpu-monkey.com/en/compare_cpu-apple_m3_max_14_cpu_30_gpu-vs-intel_core_i9_9980hk).
Single core performance of M3 Max is 2x and multi-core performance is 3x
compared to i9-9980HK.
When CPU is saturated in the test case run, the results are different.
However, the PIP430 caching continues to be superior compared to others.
