24-core desktop CPU with eight performance and sixteen efficient cores reaching 5.5 GHz, 40 MB L2 and 36 MB L3 cache, DDR5-7200 support up to 256 GB, PCIe 5.0 and 4.0 on LGA 1851, 125 W base power
Model Core Ultra 7 270K
This Intel Core Ultra 7 270K Plus desktop processor fits the LGA 1851 socket and delivers 24 cores split into 8 P-cores and 16 E-cores with 24 threads. It reaches a Turbo Boost Max Technology 3.0 frequency of 5.5 GHz while P-cores hit 5.4 GHz and E-cores 4.7 GHz. The chip carries 40 MB of L2 cache and 36 MB of L3 cache within a 125 W base power envelope.
The processor supports DDR5 7200 in dual-channel mode up to 256 GB with ECC and provides 24 lanes of PCIe 5.0 and 4.0 for graphics and storage. Integrated Intel Graphics handles display output without a discrete card. It requires an Intel 800 Series chipset motherboard so older platforms are not compatible. Users needing a lower base power target or a different socket should look elsewhere.
The LGA 1851 socket and 125 W processor base power are the single specifications that decide motherboard and cooling compatibility. Only Intel 800 Series chipset boards accept this CPU and the cooler must handle the stated thermal design power. Memory must be DDR5 and the platform delivers up to 24 PCIe lanes for expansion.

Other versions of this model
The processor fits the LGA 1851 socket found on Intel 800 Series chipset motherboards.
Align the processor notches with the socket keys, lower it straight down without touching the gold contacts, then secure the retention lever fully before applying thermal paste.
Replace the thermal paste whenever the cooler is removed or if temperatures rise above normal under the 125 W base power load.
