Comet Lake is IIRC "14+++"; so there might be some benefits there. Plus perhaps some more HW security fixes.
I should add there's no guarantee Rocket Lake is using a Cove core.
True, but I feel the timing is right for Intel to be able to pull that off, Rocket Lake 10 core Sunny Cove on super 14nm+++ could be a decent chip actually, in gaming and Single thread it probably would lay waste to Ryzen 3000..even if a higher binned Ryzen came out.
Problem is it would still get decimated in Mt and efficiency, worse still Ryzen 4000 will join the fight Q3 next year on 7nm+...probably with a few extra %IPC (2-5%) and frequency headroom @ iso power.
Rocket Lake with SunnyCove and 14nm+++ looks like a solid proposition, but if Rocket Lake is another Skylake core, well then Intel has just completely lost the Desktop market after 15 years of dominating it.
Edit; Also Icelake 15w looks like a really good product indeed, against Raven Ridge it looks like a no brainer, Intel also has a very interesting 5w product in the pipeline with ferveros tech, but again rumours of AMD Launching Renoir by years end would make things difficult as Navi mobile on 7nm would surely decimate GEN11, especially if we get lpddr4x... Or lpddr5?..
Sunny Cove would still have a sizable ST lead, depending on whether AMD uses 7+ and can push clocks up.
Other elephant in the room is those 10nm yields and OEM prices and availability, if yields are still low, then there will be low numbers of chips probably at increased prices, so AMD would get sales in even if Icelake Y is a better product.
Time will tell.
