A leak of Intel’s CPU roadmap has made its way online outlining the company’s plans all the way through 2021 and the very interesting thing is that Intel will still be on 14nm in 2021!
So starting at the top of the roadmap we have Intel’s high-end desktop (HEDT) segment, which shows that the X299 platform is here to stay and will support Intel’s upcoming Cascade Lake-X processors which features up to 18 cores on 14nm and will arrive in Q3 of 2019. This more or less confirms that there will be no major upgrade on the HEDT platform aside from higher clock speeds and an improved 14nm process node.
On the mainstream we will have the follow-up to the Coffee Lake Refresh which will be Comet Lake-S. It will feature 2 core, 4 core, 6 core, 8 core, and 10 core SKUs. All of these processors will be based on the same 14nm architecture which we have seen since Skylake so not much improvement besides increased clock speeds. With Intel adding more cores and increasing speeds expect temperatures to be pretty high, remember how hot the i9-9900K got in our testing.
The Comet Lake-S processor family is scheduled for a consumer launch in Q1 2020 and and commercial launch in Q2 of 2020. This roadmap is missing the Comet Lake successor, which will be Rocket Lake-S, which from previous leaks we know is scheduled for 2021 and will have the same 10-core 14nm design as Comet Lake, with even higher clock speeds. Finally Rocket Lake-S would be followed up by a proper 10nm or sub-10nm desktop lineup in 2022.
