For those not in the know Rapter Lake is a refresh of 12th Gen Alder Lake. If the rumours are true they will probably be released under the 14th Generation brand, October is a good time to release something because it is in time for the holiday buying season.
The October date comes from Chinese leaker ECSM, who also revealed launch windows for Meteor Lake-H in Q4 2023 and Arrow Lake-S processors at late 2024 or early 2025. The Meteor Lake-H release time frame is expected, given the teasers and working laptops that have already been spotted.
ECSM says Intel will follow its now traditional release pattern, beginning with the release of K-series SKUs in October, with non-K models to follow closer towards the end of the year just in time for the Christmas buying season. The leak suggests there's a new 8 performance +12 efficiency core model to fill the gap between the 8P+8E 13700 and 8P+16E 13900 models.
That said the Raptor Lake refresh will probably be a bit of a yawn. There might be higher clocks, even higher than those of the i9 13900KS and a better memory controller. But this is all managed by increasing he power which was already quite grim in the current 13th gen chips.
