Intel Core Ultra 5 245KF 14-core LGA1700

The Intel Core Ultra 5 245KF is a 14-core Arrow Lake desktop CPU that delivers excellent single-thread performance and strong multi-thread chops for around $200. It runs cool, supports DDR5 and PCIe 5.0, and is a great value for gaming and productivity builds with a discrete GPU. Just remember it needs an LGA 1851 motherboard, not LGA 1700.

The 245KF posts a PassMark multi-thread score of 43,112 and a single-thread score of 4,713. That single-thread number lands in the 98th percentile of all CPUs in our database, which is genuinely impressive for a $200 chip. It means snappy everyday responsiveness, fast game load times, and strong performance in lightly threaded apps. The multi-thread score is also strong, sitting around the 91st percentile, so rendering, video encoding, and heavy multitasking are all well within reach.

In practice, this translates to a processor that handles 1440p gaming with a mid-range GPU without breaking a sweat. The 14 threads are plenty for streaming while gaming, and the efficiency cores do a nice job absorbing background tasks. The 125W base power and 159W turbo are reasonable for this class, and several owners report surprisingly low temperatures under load, with one noting it stays under 40C during gaming on an AIO. That's either a silicon lottery win or just good thermal behavior from the 3nm process. Either way, it runs cool and quiet.

The obvious comparison is the AMD Ryzen 7 9800X3D. That chip is the current gaming king thanks to its 3D V-Cache, and it beats the 245KF in frame rates for cache-hungry titles. But it also costs more, and the 245KF holds its own in productivity workloads where the extra cache doesn't matter as much. If you're primarily gaming and want maximum FPS, the 9800X3D is the better pick. If you're splitting time between gaming and work, the 245KF offers better value.

Against Intel's own lineup, the 245KF replaces the Core i5-14600K in spirit. It's more efficient, runs cooler, and brings the newer platform features. The Dell Xeon E5-2637 V2 and KOMQI Core i3 BX80646I34150 that show up as competitors are older or lower-tier parts that don't really compete on modern workloads. The G.Skill Trident Z Neo and be quiet! Dark Rock Pro 5 are actually memory and cooler products, not CPUs, so they're not direct comparisons. The real fight is Intel Arrow Lake versus AMD Zen 5, and the 245KF makes a strong case for the blue team at this price point.

At $200 USD, the 245KF is a compelling deal for a 14-core Arrow Lake chip. European buyers will see prices ranging from EUR 160 to EUR 184 depending on the vendor, so it's worth shopping around. The best EUR deal in our data comes from the Spanish listing at EUR 160, which undercuts the French and Italian listings by a noticeable margin. For that money, you're getting single-thread performance that rivals chips costing significantly more. The main value question is whether you need integrated graphics. If you're building a gaming rig with a dedicated GPU, the KF saves you a few bucks over the non-F version. If you're building a home office PC without a GPU, skip this and get the regular 245K or something with an iGPU.

The Intel Core Ultra 5 245KF is a mid-range desktop processor that sits in a weirdly interesting spot. It's part of Intel's Arrow Lake-S lineup on the 3nm node, and it packs 14 cores (6 performance, 8 efficiency) with a 5.2GHz boost clock. The KF suffix means no integrated graphics, so you'll need a discrete GPU. At around $200 USD, it's aimed squarely at gamers and productivity users who want modern architecture without paying Core Ultra 7 or 9 money.

People searching for this chip usually want to know if it's good for gaming, whether it's worth upgrading from a 12th or 13th gen part, and how it stacks up against AMD's Ryzen 7 9800X3D. The short answer on gaming: it's very capable, though the 9800X3D still wins for pure frame rates in cache-sensitive titles. For productivity, this thing punches well above its price.

One thing to flag right away: the socket situation. Intel moved Arrow Lake to LGA 1851, not LGA 1700. Some listings and even the spec sheet above mention LGA 1700, but that's wrong. You'll need an Intel 800 series chipset motherboard. We saw at least one buyer get burned by this, so double-check your board before ordering.

Skip the 245KF if you don't already own or plan to buy a discrete GPU, since there's no integrated graphics to fall back on. It's also not the right pick if you're building a compact or budget office PC where the regular Core Ultra 5 245K with its iGPU makes more sense. Pure gaming enthusiasts chasing maximum frame rates should look at the Ryzen 7 9800X3D instead. And if you're on an LGA 1700 board hoping for a drop-in upgrade, this isn't it, you'll need a new motherboard, which changes the value equation significantly.

Should you buy the Intel Core Ultra 5 245KF? If you're building a new mid-range gaming or productivity PC and already have a discrete GPU, yes. It's fast, efficient, and reasonably priced. The single-thread performance is outstanding for the money, and the 14-core layout gives you headroom for multitasking and content creation. Just make sure you're pairing it with an LGA 1851 motherboard, not an LGA 1700 board.

If you're upgrading from a 12th or 13th gen Intel chip, the jump is less dramatic unless you specifically want the efficiency gains and newer platform features. And if you're a pure gamer chasing every last frame, the Ryzen 7 9800X3D remains the better choice. But for most people building a balanced system in 2025, the 245KF is an easy recommendation.
