Intel's Nova Lake-S "Core Ultra 400" Desktop CPU SKUs have leaked, which point to up to 52 cores and 150W TDP on the LGA 1954 socket.
Intel's Nova Lake-S Desktop CPUs To Offer Up To 52 Cores & 150W TDP at PL1, Coming To LGA 1954 Socket Next Year
Information regarding upcoming Intel Nova Lake-S CPU configurations has been leaked by Chi11eddog. According to the leaker, motherboard makers are very early in the development of their next-gen platforms, which will feature the LGA 1954 socket and 900-series PCH. These boards will feature next-gen technologies and support for really fast memory, with CUDIMM once again taking center stage as the memory of choice for those who want to extract the most performance out of their PCs.

Various motherboards are being verified for compatibility with over 10,000 MT/s memory speeds, which is thanks to the new integrated memory controller featured on the Nova Lake-S CPUs.
In addition to the platform details, the source also shares information about seven SKUs that will be part of the Nova Lake-S Desktop family. These include the following configurations:
- Core Ultra 9 - 16 P-Cores + 32 E-Cores + 4 LP-E Cores (150W)
- Core Ultra 7 - 14 P-Cores + 24 E-Cores + 4 LP-E Cores (150W)
- Core Ultra 5 - 8 P-Cores + 16 E-Cores + 4 LP-E Cores (125W)
- Core Ultra 5 - 8 P-Cores + 12 E-Cores + 4 LP-E Cores (125W)
- Core Ultra 5 - 6 P-Cores + 8 E-Cores + 4 LP-E Cores (125W)
- Core Ultra 3 - 4 P-Cores + 8 E-Cores + 4 LP-E Cores (65W)
- Core Ultra 3 - 4 P-Cores + 4 E-Cores + 4 LP-E Cores (65W)
The top Intel Nova Lake-S Desktop CPU will definitely be a "Core Ultra 9" part, and as per previous information, it looks like we are indeed looking at a massive core count. The chip will feature 52 cores in total, which will be a combination of 16 P-Cores, 32 E-Cores, and 4 additional LP-E cores. For comparison, the current top SKU, the Core Ultra 9 285K, features 8 P-Cores and 16 E-Cores for a total of 24 cores, and there are no additional LP-E cores. This is a 2.16x increase in the total number of cores, 2x more P-cores & E-cores. The CPU will be a top-bin with up to 150W PL1 TDP.
Top Nova Lake vs Arrow Lake Desktop CPUs:
- 2.16x More Cores (NVL-S)
- 2.16x More Threads (NVL-S)
- 4 Additional LP-E Cores per chip
- Up To 150W TDP
Moving down the stack, there's the Nova Lake-S 42 core SKU with 14 P-Cores, 24 E-Cores, and 4 LP-E cores. Now, Intel is still deciding whether to use this SKU under the Core Ultra 9 or Core Ultra 7 CPU segment, so this is still up for debate. But the chip itself will also be another 150W PL1 configuration with a massive core bump over the existing Core Ultra 7 SKU with 20 cores.
Moving further down, we have the 8 and 6 P-Core SKUs, which include three configurations. The top SKU features 8 P-Cores, 16 E-Cores, and 4 LP-E cores. That is 28 cores in total, so 4 more than the Core Ultra 9 285K. Next, we have the 8 P-Core + 12 E-Core + 4 LP-E Core, which matches the 24-core count of the Ultra 9 285K, and lastly, we have the 18-core configuration with 6 P-Cores, 8 E-cores, and 4 LP-E cores. All of these SKUs, except the 6 P-core variants, will come in 125W and 65W offerings, while the latter will come with 65W only.
