Intel is preparing the Nova Lake-S desktop processor lineup, featuring at least seven models under the Core Ultra 400 series. The flagship Core Ultra 9 4970K BFC is expected to include 28 cores, specifically 8 P-cores, 16 E-cores, and 4 LP-E cores, alongside increased Last Level Cache (bLLC) and vPro support.
The new series adopts a four-digit naming convention, potentially signaling a shift to the Core Ultra 4000 branding. Models like the 4970K BFC, 4870K BFC, and 4900 BFC feature the BFC suffix, which is linked to the larger bLLC cache configuration. These processors are designed for the new LGA 1954 socket and Intel 900 series chipsets.
Technical specifications for the lineup vary by model. The 4970K BFC and 4870K BFC are rated at 125W TDP with 32 EU integrated graphics. The Core Ultra 5 4650K and 4650F models feature 18 cores, while the energy-efficient Core Ultra 9 4900 BFC operates at a 65W TDP with 22 cores.
The architecture introduces Coyote Cove performance cores and Arctic Wolf efficiency cores. While initial leaks suggest a 28-core configuration for the first wave of products, future iterations could potentially reach 52 cores using a multi-compute module design. Peak power consumption for high-end versions may reach 296W.
Intel has begun industry standard certifications for the platform, including USB and PCIe. Mass production of the Nova Lake-S series is anticipated for the fourth quarter of 2026, with the first 28-core products expected to launch in the first quarter of 2027.
