Announced at Computex, we get the highest end CPUs from the server market ported over to the consumer side, from both Intel and AMD.
From AMD we have the 2nd Gen threadripper which slots into the already existing X399 platform.
It will launch in Q3 2018
From Intel we have what many speculate was a binned Xeon P 8180 displayed . The processor was running on a custom motherboard in the LGA3647 socket. It was cooled by a water chiller and ran 5GHz on all cores for a cinebench run. It will launch in Q4 2018.
We know nothing further on the specs of the CPU, but the final product is more likely than not a Cascade Lake X part running on the X499 platform.
