Product identity

The Intel Core Ultra 7 265 is a 20-core desktop processor built on the Arrow Lake architecture using TSMC N3B 3nm manufacturing. It fits the LGA 1851 socket and has a 65 W base power rating with 30 MB L3 cache and 36 MB L2 cache. Integrated Intel Graphics run at a 300 MHz base frequency.

Who this suits

This chip suits builders who want 8 performance cores and 12 efficient cores for mixed workloads and value ECC memory support on a two-channel DDR5 6400 MT/s controller up to 256 GB. Users needing higher sustained power limits or discrete graphics from the outset should consider other options.

Sustained-load behaviour

Under continuous load the 65 W base power keeps thermals manageable while performance cores hold 2.4 GHz and efficient cores hold 1.8 GHz. Turbo boosts to 5.2 GHz on P-cores and 4.6 GHz on E-cores are time-limited, and the 5.3 GHz Intel Turbo Boost Max 3.0 frequency applies to a single core for short bursts.

Questions about this item

What motherboard socket do I need for the Core Ultra 7 265?

The processor fits an LGA 1851 socket, so the motherboard must provide that exact socket.

Will the integrated Intel Graphics run at the 300 MHz base frequency if I keep my existing monitor connected?

Yes, the integrated Intel Graphics operates at a 300 MHz base frequency and will drive a display without a discrete GPU.

How can I verify the 20-thread CPU is reaching its 5.3 GHz Intel Turbo Boost Max Technology 3.0 frequency under load?

Use a monitoring tool to watch the P-core clocks; when a single thread hits 5.3 GHz the feature is active.
