We already knew that Intel’s 13th Gen Raptor Lake-S processors were more or less a refresh but it turns out that (other than the L2 cache) both the P and E core microarchitectures are completely identical to Alder Lake-S. Intel’s next-gen chips will feature the Raptor Cove cores as the P-cores and Gracemont (twice as many) as the E-cores. While the former has gotten a codename change, the latter remains the same.
For reference, Intel’s Top-down Microarchitectural Analysis (TMA) documentation states that Willow Cove (Tiger Lake) is not identical to Sunny Cove (Ice Lake) which in turn isn’t completely similar to Cypress Cove (Rocket Lake). We’re talking about a Coffee Lake to Comet Lake similarity with the only difference being in terms of the increased L2 cache per core (1MB->2MB).
As noted by WCCFTech, this explains why the CPU-Z single-threaded scores of Golden and Raptor Cove (at the same frequency) were almost identical. The deltas are within the margin of error.
