Some of the Rocket lake chips got delidded already, and it reveals why Rocket lake has only 8 cores.

Comet lake, having 10 cores, clocks in at 206mm². Rocket Lake, on the other hand, despite having 2 less cores, clocks in at 292mm². For comparison, the upcoming Cezanne Zen 3 APUs with 8 cores and 8 CU are with 180mm² just 60% the size of a Rocket lake die, Renoir with it's 156mm² was even just half the size of Rocket Lake.

This also explains why they reduced the size if the iGPU to only 32 EU, otherwise the chip would probably have ended up being bigger than even the old Skylake SP LCC chips, which clock in at 322mm² due to it's large caches but which could also be sold at much higher prices due to being a server chip.

Probably would have been better sticking with Skylake and throwing a big chunk of eDRAM at the problem.

I had a similar idea, just increase the size of the L2/L3 caches and Rocket Lake would probably have been beaten with less.
