For High-End Gaming and Creative Work
The Core Ultra 7 265KF is an Arrow Lake desktop processor for gamers and creators who want high clock speeds and lots of cores in one chip. Eight Performance-cores reach up to 5.4GHz, with Turbo Boost Max 3.0 taking the fastest cores to 5.5GHz, while twelve Efficient-cores handle background and multithreaded work. It uses the LGA1851 socket and supports DDR5 only, so it needs a new LGA1851 motherboard and DDR5 memory; owners of LGA1700 systems cannot drop it into their existing board. Twenty-four PCIe lanes with PCIe 5.0 support cover a current graphics card and fast NVMe storage.
KF Means Unlocked, No Graphics, No Hyper-Threading
The K means it is unlocked for overclocking on a supporting motherboard. The F means there is no integrated graphics: a dedicated graphics card is required for any display output, so choose the non-F 265K if you want built-in graphics as a backup. Thread count matches core count at 20 because Hyper-Threading is not supported on this generation. The built-in Intel AI Boost NPU, rated at 13 TOPS (Int8), supports Windows Studio Effects and AI frameworks such as OpenVINO and DirectML. With a maximum turbo power of 250W, plan for a capable cooler to keep boost clocks up under heavy load.

Questions
Before you buy
Which motherboards will this CPU fit?
It uses the LGA1851 socket, so it needs a motherboard with a matching socket. Sockets are not cross-compatible - a chip will not physically fit a board built for a different one. Every motherboard we list shows its socket on the Specifications tab, and it is worth checking the board maker’s support list for a BIOS update if the board is from an earlier generation than the chip.
How many cores and threads does it have?
20 cores and 20 threads. Cores do the work; threads are the number of jobs the chip can keep in flight at once. Games lean on a handful of fast cores, while rendering, compiling and video export scale with the total count.
What sort of cooler does it need?
It is rated at 125W TDP, which is the heat a cooler has to carry away under sustained load. Match or beat that figure with the cooler you choose, and check the What’s in the box list above - some processors ship with a cooler, some do not. Our PC Builder only offers coolers that fit the socket you have picked.
Do I need a separate graphics card with it?
Yes. This processor has no integrated graphics, so you will need a graphics card in the machine for it to output any picture at all. Budget for one in the build rather than treating it as a later upgrade.
Is it in stock, and when will it ship?
This one is out of stock at the moment. Stock does come back in - WhatsApp us on 079 491 0181 with the model and we will tell you what the supplier is showing and let you know when it lands, rather than leaving you to keep checking the page.
What does delivery cost, and how long does it take?
We deliver by courier anywhere in South Africa, and delivery is R180 on orders under R2 500 and free on orders of R2 500 or more. It takes 1-3 working days to Johannesburg, Pretoria, Cape Town, Durban and areas within 100km of them, and 2-4 working days to areas more than 100km from a major centre, counted from the day the order is dispatched. Need it sooner? Express delivery is 1-2 working days for R210, or R150 on orders of R2 500 or more - choose it at checkout. We do not ship outside South Africa.
Can I collect instead of having it delivered?
Yes. Collection is from 11 Voortrekker Avenue, Edenvale, Gauteng, by arrangement - message us first so we can have the order picked and waiting. We are open 09:00 to 16:30, Monday to Friday.
What warranty does it carry, and how do I claim?
The warranty period for this product is listed at the end of the Specifications section above. Claims go through us, not the manufacturer - contact us with your order number and a description of the fault and we will handle it from there. Separately from any warranty, the Consumer Protection Act gives you six months from delivery to return goods that are defective, unsafe or not fit for their intended purpose.
What if I change my mind?
You have 14 days from delivery to change your mind - longer than the seven days the Electronic Communications and Transactions Act requires. The item needs to be unused and in its original packaging, and we pay the return shipping. Refunds go back to the payment method you used, within 30 days of the return reaching us.
How can I pay?
Payments are processed by Stitch. At the last step of checkout you are taken to Stitch’s secure page to pay, and brought back here once it is done. Your card details are entered on Stitch’s secure, PCI-compliant page and never touch our systems.
