Intel Nova Lake-S Desktop CPUs Revealed: Up to 52 Cores Including 16 P-Cores and 32 E-Cores, 150W TDP; Entry-Level Models with 12 Cores

Recent leaks regarding Intel’s Nova Lake-S “Core Ultra 400″Desktop CPU series reveal a significant advancement in processing power, with configurations boasting up to 52 cores and a thermal design power (TDP) of 150W, designed for the LGA 1854 socket.

Unveiling the Intel Nova Lake-S Desktop CPUs: Up to 52 Cores & 150W TDP Coming in 2025

Intel’s future Nova Lake-S CPU offerings have been the subject of scrutiny thanks to informative leaks from Chi11eddog. Insight shared indicates that motherboard manufacturers are in the preliminary stages of developing their next-generation platforms. These will incorporate the LGA 1854 socket alongside the latest 900-series Platform Controller Hub (PCH).This progress denotes a return to advanced memory technologies, with CUDIMM emerging as the optimal choice for enthusiasts seeking peak performance.

Furthermore, several motherboards are being evaluated for compatibility with memory speeds exceeding 10, 000 MT/s, enabled by a newly integrated memory controller featured in the Nova Lake-S CPUs.

Core Configuration Details of Nova Lake-S CPUs

Alongside platform details, the leaks also specify seven distinct WeUs within the Nova Lake-S Desktop family. Here’s a breakdown of the anticipated configurations:

  • Core Ultra 9: 16 Performance (P) Cores, 32 Efficient (E) Cores, and 4 Low Power Efficient (LP-E) Cores (150W)
  • Core Ultra 7: 14 P-Cores, 24 E-Cores, and 4 LP-E Cores (150W)
  • Core Ultra 5: 8 P-Cores, 16 E-Cores, and 4 LP-E Cores (125W)
  • Core Ultra 5: 8 P-Cores, 12 E-Cores, and 4 LP-E Cores (125W)
  • Core Ultra 5: 6 P-Cores, 8 E-Cores, and 4 LP-E Cores (125W)
  • Core Ultra 3: 4 P-Cores, 8 E-Cores, and 4 LP-E Cores (65W)
  • Core Ultra 3: 4 P-Cores, 4 E-Cores, and 4 LP-E Cores (65W)
Intel Core Ultra 200S

The flagship CPU in the Nova Lake-S lineup—the Core Ultra 9—will set a new benchmark with a staggering total of 52 cores, featuring a configuration of 16 P-Cores, 32 E-Cores, and 4 LP-E cores. This represents a considerable leap from the current top model, the Core Ultra 9 285K, which offers merely 8 P-Cores and 16 E-Cores for a total of 24 cores, thus achieving a 2.16x increase in core count along with a doubling of both P-Cores and E-Cores. This feature continues to maintain a 150W PL1 TDP.

Next in line is a configuration with 42 cores, comprising 14 P-Cores, 24 E-Cores, and 4 LP-E cores. Discussions within Intel are ongoing regarding whether to classify this as a Core Ultra 9 or Core Ultra 7 model. Regardless, this also adheres to the powerful 150W PL1 configuration, showcasing a significant jump over the current 20-core offering of the Core Ultra 7 multiple.

Lower down the hierarchy, the CPUs featuring 8 and 6 P-Cores will include three variations. The highest of these will offer 28 cores total: 8 P-Cores, 16 E-Cores, and 4 LP-E cores—exceeding the Core Ultra 9 285K by 4 cores. The second configuration matches the Core Ultra 9 285K with 8 P-Cores, 12 E-Cores, and 4 LP-E cores for a total of 24 cores, followed by an 18-core design consisting of 6 P-Cores, 8 E-Cores, and 4 LP-E cores. Most of these WeUs, except for the 6 P-Core models, will be available in 125W and 65W offerings, with the latter exclusively capped at 65W.
