Intel Core Ultra 5 245K 14-core LGA1851

The Core Ultra 5 245K posts a 4,719 single-thread PassMark score, good for the 99th percentile, and a 43,121 multi-thread score in the 91st percentile. Efficiency is a real strength at 125W TDP on the 3nm node. But user sentiment sits at just 65/100, the 11th percentile, so early owner feedback is a mixed bag at best.

The 4,719 single-thread score is the headline here. That's top of the charts territory, best-in-class for anything you'd actually buy for a desktop build. The 43,121 multi-thread result is also strong, landing in the 91st percentile. For context, that's a 14-thread chip keeping pace with much more expensive hardware. The 24MB of L3 cache and 26MB of L2 cache give it plenty of breathing room for gaming and light content creation.

The 3nm TSMC N3B process node is doing real work here. The 125W TDP with a 159W turbo ceiling means this thing sips power compared to the space heaters Intel was shipping a few generations ago. The efficiency score sits in the 89th percentile, which backs that up. The 13 NPU TOPS is modest by AI accelerator standards, but the AI score still lands in the 91st percentile, so it's clearly not holding the chip back for most workloads.

The Ryzen 7 9800X3D is the obvious rival here, and it's a genuine threat. The 9800X3D brings 3D V-Cache to the table, which absolutely dominates in gaming workloads where cache matters more than raw clock speed. The 245K counters with better efficiency and a lower platform cost if you catch a deal. Against older Intel parts like the i9-9960X or i9-7940X, the 245K wins on single-thread performance by a mile, though those X-series chips still hold an edge in heavily threaded server-style workloads. The Xeon E5-2696v4 is a different beast entirely, old but with way more cores for parallel tasks. The 245K's 77.4 server score tells you it's not trying to play in that sandbox.

Pricing is all over the place right now. USD listings range from $185 to $327 across four vendors, which is a $142 spread. That's not a small gap, that's the difference between a no-brainer and a hard pass. If you can snag this near the $185 mark, you're getting 99th percentile single-thread performance for budget CPU money. At $327, you're in territory where the Ryzen 7 9800X3D starts looking very tempting. The CAD spread is tighter at $228 to $310, an $82 gap, but the same logic applies. Shop around before you commit.

The Core Ultra 5 245K posts a 43,121 PassMark multi-thread score and a 4,719 single-thread score. That single-thread number lands in the 99th percentile of every CPU in our database, which is the kind of result that makes productivity folks sit up and pay attention. The 14-core setup (6 performance, 8 efficiency) on Intel's new 3nm Arrow Lake architecture is a genuine architectural shift, not just a refresh with a new name slapped on it.

But here's the thing. The user sentiment score sits at 65/100, which is the 11th percentile. That's rough. The sample size is tiny, just 8 pieces of evidence, so we're not going to pretend it's a definitive verdict. But when the spec sheet says one thing and early owners are lukewarm, that mismatch is worth digging into.

If you're running heavily threaded server workloads, look elsewhere. The server score of 77.4 out of 100 is the weakest area by a wide margin, and 14 threads just isn't enough for serious parallel processing. If you already have an LGA1700 system, the platform cost of a new motherboard makes this a tougher sell. And if you're a gamer who prioritizes frame rates above all else, the Ryzen 7 9800X3D's 3D V-Cache is going to serve you better in most titles. The 245K is a productivity chip first.

The Core Ultra 5 245K is a genuinely impressive piece of silicon on paper. The 99th percentile single-thread score and 91st percentile multi-thread result are hard to argue with, and the 3nm efficiency gains are real. But the 11th percentile user sentiment score gives us pause. The sample is small, so we're not calling it a dud, but early adopters aren't exactly raving. If you find it at the low end of that $185 to $327 range and you're building a new LGA1851 system anyway, it's a solid pick. If you're paying full price, the 9800X3D is breathing down its neck.
