It is an unusual way to make your newer 13th-gen Raptor Lake processors, which come with more cores and drastically faster performance, look better. Increasing the price of the older chips makes them less expensive than the previous-gen models.
Intel announced during the first quarter of 2022 that it would increase chip pricing, but didn't tell anyone what its cunning plan was. In June Intel announced it had lost $500 million in the second quarter of 2022 - one of the worst quarters in the company's history.
Intel lists a $10 price range for its processors ($589 to $599, for example). Intel has hiked the Alder Lake desktop CPUs by 10% across the entire range spanning from the Core i3 to Core i9 models. In the case of the highest-end Core i9-12900K there was an increase of $59.
The graphics-less F-series models, which typically come at a discount, have seen price increases along with the 65W and 35W "non-K" models.
