It appears that Intel’s 10nm Ice Lake-based desktop CPUs might be further delayed. According to a report from ASCII Japan, the expected date for the mainstream chips has still not been decided due to poor yields and might not be as close as Intel wants you to believe. Furthermore, the Ice Lake-U and Y based motherboards will be very limited in quantity while the Ice Lake SP processors will be restricted by the clocks. Not very promising news for team blue considering AMD’s recent launches.

The mobile Ice Lake CPUs are currently being shipped and notebooks featuring them should start hit
Q2 2020: 10 Core Comet Lake Desktop CPUs (10 Cores/10 Threads)

The Comet Lake CPUs are supposed to launch for all markets at the same time, from the desktop-based S, mobile-based Y and U and possibly even the SP parts. Comet Lake will leverage the 14nm process like Coffee Lake and from what we know won’t be too different either. These SKUs will feature up to 10 cores, but thanks to the Zombieland exploit will lack hyper-threading. From what we’ve heard, it’s impossible to mitigate the impacts of the vulnerability without disabling HT.
