Intel Core Ultra 5 245K 14-core LGA1851
Built on TSMC’s 3nm process, the unlocked 14-core Arrow Lake architecture delivers a 5.2GHz boost and a substantial 26MB L2 cache for strong single and multi-threaded throughput. Its 13 NPU TOPS and integrated Intel Graphics provide a capable on-chip AI engine and display output without a discrete GPU, keeping platform costs down. This processor is best for budget-conscious productivity builders and AI hobbyists who need modern PCIe 5.0 and DDR5 support without paying for excessive core counts.

요약
The 30-Second Version
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.
Pros & Cons
장점
- Single-thread score of 4,719 is in the 99th percentile, absolute top of the charts 99th
- 43,121 PassMark multi-thread score puts it in the 91st percentile 97th
- 3nm Arrow Lake architecture delivers 89th percentile efficiency at 125W TDP 96th
- 24MB L3 and 26MB L2 cache give it serious headroom for gaming and productivity 91st
- Unlocked multiplier and LGA1851 socket mean real overclocking headroom
단점
- User sentiment score of 65/100 lands in the 11th percentile, a real red flag
- Only 14 threads total, so heavily threaded workloads hit a ceiling fast
- Server performance is the weakest area at 77.4/100
- Requires a new LGA1851 motherboard, no drop-in upgrade path from LGA1700
- Social proof is thin at the 70th percentile with just 29 reviews

Performance
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.

vs Competition
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.

Value & Pricing
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.

Overview
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.
Common Questions
Q: Is the 245K a meaningful upgrade from an older i7-9700K?
Yes, and the numbers back it up. The 245K has 14 cores (6P+8E) versus 8 cores on the 9700K, and the single-thread score of 4,719 is in the 99th percentile. You're looking at a massive jump in both single-threaded and multi-threaded performance, plus a move to DDR5 and PCIe 5.0.
Q: What power supply do I need for this CPU?
The 245K has a 125W TDP with a 159W turbo ceiling. A quality 650W power supply is plenty for most builds with a mid-range GPU. The chip uses the LGA1851 socket, so you'll need a new 800-series motherboard regardless of what PSU you pick.
Q: How does the 245K handle AI workloads?
The AI score lands in the 91st percentile, which is strong. The 13 NPU TOPS is modest compared to dedicated accelerators, but for consumer AI tasks and light LLM work, the combination of the NPU and the 14-core CPU handles things well. The AI/LLM use case score of 89.2 out of 100 reflects that.
Who Should Skip This
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.
Verdict
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.
