Intel Core i7 8700K Linux Benchmarks

The Intel CPUs were doing much better than Ryzen with the Java JMH harness.

And with the more demanding task of compiling the LLVM compiler stack, the Core i7 8700K squeezed by the Ryzen 7 1800X as faster.

The i7-8700K was also faster than the 1800X with the 7zip compression performance.

Those are the Core i7 8700K Coffee Lake benchmarks I have available this morning. Overall, the CPU performance of the Core i7 8700K is notably better than the i7-7700K Kaby Lake in many tests largely due to the addition of the two extra cores with any microarchitecture benefits waiting until Cannonlake. This allowed the Core i7 8700K to better compete with the top-end Ryzen 7 CPUs even though they still led on the core/thread count. The Core i7 8700K was most often competing between the Ryzen 7 1700 and 1800X, but often surpassing the Ryzen 7 1800X, except in cases where the workload is solely bound by the available threads. In tests involving IPC, etc, the Intel CPUs still did much better than these first generation Zen CPUs.

I will have more Linux benchmarks shortly, still investigating the UHD Graphics 630, and some BSD tests will be on the horizon too. Thanks to Intel for supplying the Coffee Lake samples and ASUS for providing the PRIME Z370-A motherboard.
