Good news, the new upcoming 8-core Coffee lake part might be based on an existing architecture they are however based on new silicon, Intel has been able to apply a number of Meltdown... Meltdown Fixes In hardware for new Core Desktop Processors
and they released all the shiny x299 boards today...yikes good for the Coffee Lake though and a relief
Don't you think that it's sad that Intel didn't changed/improved the "All New 28C!!!" Xeon W-3175X and released it as is just with stim and unlocked multi without fixing the Meltdown and etc ? it's a XEON and security should be on top, OMG - That what you get for letting Marketing team Run your Company! .
Before they don't fix ALL of it inside the chip it's only a PR stunt. Everything that has to be run by the OS cripples performance. I wonder if the reviews even bench with all the security patches enabled...
Glad to know Intel is working on this with their latest micro-arch refresh - far as Xeons are concerned I agree that was sad but likely will be addressed in upcoming firmware updates to Enterprise clients & board partners to come. I'm not sure if SMT can be modified to the point of near overhaul via micro-code updates but perhaps. To address more when they get around to it.
