Non-K 13th Gen Core i5 (such as i5-13400) Based on Older "Alder Lake" Architecture, Hints Intel Slide
Remember how 12th Gen Core i5 non-K was vastly different in performance from the Core i5 K/KF on account of being 6P+0E processors in comparison to more L3 cache and a 6P+4E core-count of the i5-12600K/KF? Intel is doubling down on creating architectural confusion in the mid-range, according to a 3DCenter.org article citing a leaked slide from Intel’s 13th Gen Core launch press-deck.
We had earlier thought that the 13th Gen non-K Core i5 will have a 6P+4E core-config, but still be based on "Raptor Lake" (i.e. "Raptor Cove" P-cores + "Gracemont" E-cores), in comparison to the i5-13600K/KF, which are confirmed "Raptor Lake" chips with 6P+8E configuration; but it turns out that Intel is basing the non-K 13th Gen Core i5 on the older "Alder Lake" microarchitecture. These chips will be 6P+4E (that’s six "Golden Cove" P-cores + four "Gracemont" E-cores), which make them essentially identical to the i5-12600K, but without the unlocked multiplier, and a lower 65 W processor base power.
