Intel Core Ultra 5 250KF Plus 18-core LGA1851

The Intel Core Ultra 5 250KF Plus is an 18-core desktop CPU with excellent single-thread and multi-thread performance. It requires a discrete GPU and an LGA1851 motherboard. At the low end of its USD 200 to USD 415 price range, it's one of the best values in desktop processors.

The PassMark scores tell a pretty clear story. The 250KF Plus hits 48,416 in multi-thread and 4,587 in single-thread. That single-thread score lands in the 97th percentile of all CPUs in our database, which is the absolute best right now for this class of chip. The multi-thread score is also a standout at the 93rd percentile. In practice, that means this processor chews through productivity workloads, video encoding, and heavy multitasking without breaking a sweat. The 18 threads help a lot here, and the 5.3GHz boost clock keeps single-core tasks snappy.

For gaming, the 250KF Plus is more than capable. The 30MB of L3 cache and 30MB of L2 cache keep frame times smooth, and the high single-thread performance means it won't bottleneck most mid-range and high-end GPUs. It's not going to beat the Ryzen 7 9800X3D in cache-sensitive games, but it's not trying to. The 125W base TDP and 159W turbo draw are reasonable for this level of performance, and the chip is unlocked for overclocking if you want to push it further. DDR5 support with up to 256GB of memory and ECC compatibility gives it some workstation chops too.

The obvious comparison is the AMD Ryzen 7 9800X3D. That chip is the gaming king right now thanks to its massive 3D V-Cache, and it beats the 250KF Plus in cache-sensitive titles. But the 250KF Plus counters with more cores, better multi-thread performance, and a lower price when you shop smart. If you're building a pure gaming rig and budget isn't a concern, the 9800X3D is the better pick. If you do a mix of gaming and productivity work, the 250KF Plus is the more balanced choice.

The other competitors in our database are older high-end parts like the Core i9 X-Series chips and Xeon E5-2696v4. Those are workstation and server processors from previous generations, and they don't really compete with the 250KF Plus for typical desktop use. The G.Skill Trident Z Neo is memory, not a CPU, so it's not a direct comparison either. The 250KF Plus is really competing against AMD's mid-range Ryzen parts and Intel's own previous-gen Core i5 and i7 chips, and it holds its own against all of them.

Value is where this gets interesting. The USD 200 to USD 415 spread means your experience depends entirely on where you shop. At USD 200, this chip is one of the best deals in desktop CPUs right now. At USD 415, you're paying a premium that puts it uncomfortably close to more specialized options. The CAD 280 to CAD 290 range is much tighter and more reasonable. If you can find it near the low end of the US range, buy it without hesitation. If you're looking at the high end, consider waiting for a sale or checking Canadian retailers. The Ryzen 7 9800X3D costs more but offers better gaming cache performance, so the 250KF Plus makes the most sense when you're getting it at a discount.

The Intel Core Ultra 5 250KF Plus is a mid-range desktop CPU that punches way above its weight class. It's built on Intel's Arrow Lake Refresh architecture using a 3nm process, and it packs 18 cores split between 6 performance cores and 12 efficiency cores. That's a lot of silicon for a chip in this bracket, and it shows in the numbers. The 250KF Plus sits in the LGA1851 socket, so you'll need an Intel 800 Series motherboard to run it. One thing to know right away: there's no integrated graphics here. The KF suffix means you'll need a discrete GPU, which is fine for gamers but worth remembering if you were planning a budget build without one.

Pricing is all over the place right now. We're seeing USD 200 to USD 415 across four US listings, and CAD 280 to CAD 290 in Canada. That's a USD 215 spread depending on where you shop, so it pays to check around before you buy. At the low end, this thing is an absolute steal. At the high end, it's still competitive but less of a no-brainer.

People searching for this chip are usually asking the same things: is the Core Ultra 5 250KF Plus good for gaming, how does it compare to the Ryzen 7 9800X3D, and does it need a discrete GPU. We'll get into all of that below. Short version: yes, it's good for gaming, the 9800X3D is a different beast entirely, and yes, you need a graphics card.

Skip the 250KF Plus if you're building a system without a discrete GPU, since there's no integrated graphics to fall back on. It's also not the right choice if you're running server workloads, where its performance is mediocre compared to dedicated server chips. If you're a pure gamer with a flexible budget, the Ryzen 7 9800X3D will serve you better in cache-sensitive titles. And if you already have an LGA1700 motherboard, the cost of upgrading to an LGA1851 board might make a previous-gen Intel chip or an AM5 Ryzen build more economical.

Should you buy the Intel Core Ultra 5 250KF Plus? If you can find it at or near USD 200, absolutely. It's a fantastic all-rounder with top-tier single-thread performance, plenty of cores for productivity, and modern platform features like PCIe 5.0 and DDR5. The lack of integrated graphics is a non-issue for most people building a gaming or workstation PC, since you'll want a discrete GPU anyway.

At the higher end of the price range, it's a tougher sell. The Ryzen 7 9800X3D is a better pure gaming chip, and the price gap narrows enough that you should think hard about what you actually need. But for a balanced build that handles gaming, streaming, and productivity without costing a fortune, the 250KF Plus is one of the best options in its class right now.
