In heavily threaded applications, it was no contest, AMD Zen smacked Intel's latest i-Core, forcing Intel to quickly' re-brand their next generation, and even pull in their Xeon high core count (at a loss of speed) as the i9 consumer/workstation product. </div><div dir="auto"><br></div><div dir="auto">It will be interesting to see where Zen2 ends up, and how the 7nm yields are coming out of TSMC, but right now it's not looking good for Intel this year in the consumer/workstation space.
