Eighteen cores, DDR5-7200 and Xe graphics — the 250KF with display output added.
Quick Specs
- 18 cores (6 P-cores + 12 E-cores) / 18 threads
- 4.2GHz P-core base, up to 5.3GHz turbo
- 30MB Intel Smart Cache
- Intel Graphics, 4 Xe-cores; 13 TOPS NPU
- 125W base power, 159W max turbo
The complete mid-range Core Ultra
Everything the 250KF offers — eighteen cores, 30MB of cache, a 4.2GHz base and 5.3GHz turbo, DDR5-7200 support — with four Xe graphics cores enabled on top. That means the machine boots, displays and plays video with no graphics card, which is worth having both for troubleshooting a gaming build and for a workstation that doesn't need one at all. The unlocked multiplier leaves tuning headroom on Z890.
Only pay for the graphics if you'll use them
In a build where a discrete card goes in immediately and permanently, the 250KF is the identical processor for less. And keep expectations realistic on the Xe graphics: four cores is enough for desktop, video and light 3D, not for gaming. As always with Core Ultra, no Hyper-Threading — eighteen cores, eighteen threads. No cooler in the box; a good tower cooler handles the 159W ceiling comfortably.
FEATURES:
- 18 cores at up to 5.3GHz with 30MB Smart Cache
- Intel Graphics with 4 Xe-cores — display output without a card
- DDR5 support up to 7200 MT/s

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?
18 cores and 18 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?
No - this processor has integrated graphics, so it will drive a display on its own. You still want a graphics card for gaming or GPU-accelerated creative work, but the machine will boot and run without one.
Is it in stock, and when will it ship?
Yes - this one is in stock. Order before 12:00 on a working day and it ships the same day; after that it goes out the next working day. We are open 09:00 to 16:30, Monday to Friday, so an order placed over a weekend or a public holiday ships on the next working day.
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.
