Intel Core Ultra 9 4950K Review
The Intel Core Ultra 9 4950K is a rumored Nova Lake-S desktop processor that leaked as a 28-core chip (8 P-cores and 20 E-cores) tested on a Z990 board for the new LGA1954 socket, as reported by VideoCardz, Notebookcheck and TechPowerUp.
Intel has not confirmed the name or specs, so everything here is based on leaks and may change before launch. Leaked partner roadmaps covered by Wccftech point to the first 28-core Nova Lake-S chips arriving in Q1 2027.
