Intel's flagship Nova Lake 52-core CPU reaches 474W power limit with LGA1954 socket, requiring multi-pin 8-pin connectors.

Intel is expected to push the boundaries on power draw with its upcoming Nova Lake series processors. According to newly leaked information confirmed by Jaykihn, who has a solid track record with Intel hardware, the flagship 52-core desktop variant is expected to feature a dual-compute tile architecture with a PL2 (Power Limit 2) target of 474W. PL2 represents the maximum power a CPU can draw during short boost periods. Previous rumors suggest Intel may also implement a PL4 emergency power limit exceeding 700W, though these power specifications are believed to apply only to top-end dual-tile models.

The new platform will use the LGA1954 socket and require a new generation of motherboards. Motherboard vendors are expected to classify their boards by sustained PL1 power levels, with configurations for 35W, 65W, 125W, and 175W CPUs. Enthusiast-grade motherboards in the Z990 series are rumored to feature three EPS 8-pin CPU power connectors instead of the traditional two. While manufacturers will have the option to include a third connector, it is intended primarily to support extreme overclocking and will not affect the CPU's rated performance profile.

The upcoming Nova Lake-S lineup will carry the "Core Ultra 400S" moniker and represents Intel's biggest desktop CPU overhaul in years. Leaked specifications indicate configurations ranging from 6 to 52 cores with support for DDR5-8000 memory. The flagship 52-core model is expected to feature 16 performance cores and 32 efficiency cores, paired with a new Big Last Level Cache (bLLC) design to compete with AMD's 3D V-Cache gaming performance. The platform is also rumored to introduce integrated Xe3 graphics, Thunderbolt 5, PCIe 5.0 connectivity, and an upgraded NPU for AI workloads.

While these specifications remain unconfirmed, Intel is clearly targeting substantial gains in gaming, multi-threaded performance, and overall platform capabilities with its next-generation processors.
