Intel Core Ultra 7 270K Plus desktop processor

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.

Suits builders who need high core counts and fast

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.

LGA 1851 socket and 125 W base power define

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.

Questions about this item

What motherboard socket does the Core Ultra 7 270K Plus require?

The processor fits the LGA 1851 socket found on Intel 800 Series chipset motherboards.

What is the critical step when installing this CPU into the LGA 1851 socket?

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.

When should the thermal interface material be replaced on the Core Ultra 7 270K Plus?

Replace the thermal paste whenever the cooler is removed or if temperatures rise above normal under the 125 W base power load.
