Intel showcased the 28-core HEDT CPU right after the 40th anniversary i7-8086K presentation at Computex. The 28-core CPU was stably running at 5 GHz and overclockers will probably get the beastly chip running at more than 6 GHz. It is expected to hit the markets in Q4 this year, but the MSRP could be around US410,000.
