Intel's next-gen Nova Lake-S desktop CPU leaks: up to 52 cores with 16 P-Cores, 150W TDP

Intel's next-gen Nova Lake-S desktop "Core Ultra 400" series CPU details have leaked, teasing that we can expect up to 52 CPU cores, with up to 150W TDP on the new LGA 1854 socket.

The new information on the next-gen Nova Lake-S desktop CPUs comes from leaker @Chi11eddog on X, reporting that motherboard makers are "very early" in the development of their next-gen platforms based on the new 900-series chipset and LGA 1854 socket. We can expect next-gen tech features and support for even faster DDR5 memory, with CUDIMM at the center for users who want ultimate performance out of their gaming PCs.

Intel is expected to support up to ultra-fast DDR5-10000+ memory on its new 900-series motherboards, with leaks of 7 new SKUs of Core Ultra 400 series with the flagship Core Ultra 9 SKU featuring 52 cores (16 P-Cores + 32 E-Cores + 4 LP-E Cores) with a 150W TDP. Compare this with the current-gen flagship Core Ultra 9 285K "Arrow Lake-S" desktop CPU which features 8 P-Cores and 16 E-Cores for a total of 24 cores (with no LP-E cores), meaning we're in for a 2.16x increase in core count, with 2 x more P-Cores and E-Cores.

The new Core Ultra 7 offering in the Nova Lake-S family rocks more CPU cores than the current flagship Core Ultra 9 processor, with 14 P-Cores and 24 E-Cores joined by 4 LP-E cores for a total of 28 cores, meaning we've got 4 more cores than the current Core Ultra 9 285K chip. The new Core Ultra 5 series CPUs in the Nova Lake-S platform should also impress, offering 8 P-Cores and 16 E-Cores joined by 4 LP-E cores.

• 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)
