Overview
Intel's Core Ultra 7 265KF puts 20 cores, 8 performance plus 12 efficiency, onto a chip peaking at 5.5GHz. It requires an Intel 800 series chipset motherboard and a separate graphics card.
The KF suffix carries two things worth knowing before buying: K means it's unlocked for overclocking, and F means it ships without integrated graphics, so a discrete graphics card is required just to get a display signal. Beyond that it's a hybrid design, 8 performance cores for single-thread heavy work paired with 12 efficiency cores for background and multi-threaded loads, peaking at 5.5GHz on the P-cores. It needs a new Intel 800 series chipset motherboard rather than dropping into an older Intel board.
- 8 performance cores plus 12 efficiency cores, 20 total
- Up to 5.5GHz peak clock speed
- Unlocked (K) for overclocking
- Pairs with Intel 800 series chipset motherboards
Who it's for
Suited to builders assembling a new Intel platform who already own a graphics card and want P-core-plus-E-core scaling for mixed gaming and productivity work. Not for anyone who needs onboard graphics for basic display output or wants to reuse an older Intel motherboard.
Pros and cons
- 20 cores split across performance and efficiency
- Peak clock up to 5.5GHz on performance cores
- Unlocked for overclocking
- No integrated graphics, a discrete GPU is mandatory
- Requires a new Intel 800 series motherboard
Performance notes
The 8 performance cores carry single-threaded and gaming workloads up to the listed 5.5GHz peak, while the 12 efficiency cores handle background tasks and multi-threaded work without pulling from the P-core budget. Because it lacks integrated graphics, all display output depends on whatever discrete card is installed. Chipset support is limited to Intel's 800 series boards, so it requires new motherboard hardware rather than fitting an existing socket from earlier Intel generations.
