October 2, 2026 at 10:05 AM

> A new leak reveals seven Intel Nova Lake-S desktop processors, including a flagship 28-core chip featuring big last-level cache technology.

A new leak from @laurentschoice has revealed seven upcoming [Intel](<https://hardwarebrief.com/entity/intel-q248>) [Nova Lake-S](<https://hardwarebrief.com/entity/nova-lake-microprocessor-q136549148>) desktop processors using a Core Ultra 4000 naming convention. The flagship **Core Ultra 9 4970K BFC** leads the lineup, featuring 28 total cores and a 125W rating for enthusiasts.

The leak highlights the introduction of big last-level cache (bLLC) on select models like the 4970K BFC and 4870K BFC. While a previous CPU-Z leak suggested the 4950K had 28 cores, this new data lists it as a 24-core chip without LPE cores or bLLC support.

Intel's bLLC technology aims to compete with [AMD](<https://hardwarebrief.com/entity/amd-q128896>)'s 3D V-Cache, with the top 28-core chip reportedly reaching 296W at PL2. While Intel has not confirmed these names, qualification samples are appearing in [HWiNFO](<https://hardwarebrief.com/entity/hwinfo-q3927938>) ahead of a projected Q1 2027 launch window.
