Intel "Raptor Lake" Core i9 Sample Powers Up, 8P+16E Configuration Confirmed
An engineering sample of a 13th Intel Core "Raptor Lake" Core i9 processor hit the web, courtesy of wxnod on Twitter, which confirms its 8P+16E core-configuration in a CPU-Z screenshot. Based on the same LGA1700 package as "Alder Lake," and backwards compatible with Intel 600-series chipset motherboards, besides new 700-series ones, "Raptor Lake" combines eight "Raptor Cove" performance cores (P-cores), with sixteen "Gracemont" efficiency cores (E-cores).
"Raptor Cove" features a generational IPC increase over the "Golden Cove" P-cores powering "Alder Lake," while the "Gracemont" E-cores, although identical to those on "Alder Lake," are expected to benefit from the doubling in L2 cache per cluster, from 2 MB to 4 MB. The ISA as detected by CPU-Z appears to be identical to that of "Alder Lake." The processor is a monolithic silicon chip built on the Intel 7 (10 nm Enhanced SuperFin) silicon fabrication process.

Exactly the way it should be, the most efficient. No weird latency issues between chiplets this way.
RL might finally be the generation that I upgrade my ancient 2700K to, assuming the tanking economy doesn't make me too poor to afford it that is.
Since 8 cores are kinda OK with the tasks you throw at it in a regular desktop home environment. More pcores would be reserved for server segment or HEDT where you pay extra for these.
I wouldn't be surprised if this thing rendered faster than a 5950X. It's 24 cores vs 16 cores and for rendering, AMD gets about 1.4 effective cores out of SMT. I think an E-Core is more than 40% the performance of a P-Core, especially in a PL2-limited full-load scenario, and Intel's P-cores render slightly faster than a Zen3 core.
I was joking earlier..
There is a reason why Sapphire Rapids remains all P-core design..
