Intel Core Ultra 7 265KF Arrow Lake Desktop

The Intel Core Ultra 7 265KF is a 20-core desktop processor built on the Arrow Lake architecture. It combines eight performance cores with twelve efficient cores for a total of twenty threads. The chip fits the LGA 1851 socket and operates at a 125W thermal design power. Maximum turbo frequencies reach 5.5 GHz on the performance cores and 4.6 GHz on the efficient cores.

Suited for Multi-Threaded Workloads

This processor targets users who need high multi-thread throughput for content creation, compilation or heavy multitasking. The lack of integrated graphics means a discrete graphics card is mandatory for any video output. Builders who require Quick Sync or a display output without a separate GPU should consider a non-KF variant instead.

LGA 1851 Socket and DDR5-6400 Dual-Channel Memory

The CPU supports DDR5 memory up to 6400 MT/s across two channels with a maximum capacity of 192 GB. It provides twenty-four PCI Express lanes split between the 5.0 and 4.0 revisions for graphics and storage expansion. A cooling solution is not included in the package and must be sourced separately.

Questions about this item

Will the LGA 1851 socket require a new cooler bracket when I upgrade the CPU later?

The processor fits the LGA 1851 socket; cooler mounting depends on the motherboard and cooler manufacturer, so check their compatibility lists for this socket.

Does the 125 W base power or the 250 W max turbo power limit sustained all-core performance first?

The 250 W maximum turbo power is the ceiling the CPU will hit under heavy all-core loads before thermal throttling or power limiting engages.

How loud and hot does the 20-core Arrow Lake chip run when all cores stay at 4.6 GHz E-core speed all day?

With a 125 W base and 250 W max turbo, sustained all-day loads need a strong cooler; noise and temperature depend entirely on the cooling solution you choose.
