Chrome compilation should be heavily parallelized. (It is my core use case. I only care about system big project compilation speed. )

The report seems to show Intel 4C/8T is doing better than AMD 8C/16T with much bigger L2/L3 cache config.

Is 7700K really that good? Can anyone from AMD explain this?

Intel (Kaby Lake) Core i7 7700K (91W, $339) 4C/8T, 4.2 GHz, 1MB L2, 8MB L3 17.81

AMD (Zen) Ryzen 7 1800X (95W, $499) 8C/16T, 3.6 GHz, 4MB L2, 16MB L3 16.32
