Intel Core Ultra 285K 24-core LGA1851

The Intel Core Ultra 285K is a 24-core Arrow Lake-S monster with best-in-class single-thread performance and excellent multi-thread and AI scores. At $840 USD bundled with a Z890 Tomahawk WiFi board, it's a strong value for productivity and AI builders. Gamers might prefer the Ryzen 7 9800X3D, but for everything else, this chip is hard to beat.

The raw numbers here are serious. PassMark puts the 285K at 67,259 multi-thread and 5,087 single-thread. That single-thread score is the absolute best we've seen in our database, top of the charts. For everyday responsiveness, app launches, and lightly threaded tasks, this thing is as fast as it gets right now. The multi-thread score is also a standout, landing in the 97th percentile. Rendering, compiling, video encoding, this chip chews through it.

But the real story is the AI performance. Intel gave this chip a 13 TOPS NPU, which is modest compared to some mobile parts, but combined with the CPU and iGPU, it handles local AI workloads well. Our AI score puts it in the 96th percentile. If you're running local LLMs or AI-assisted productivity tools, the 285K is one of the best desktop options available. The 40MB of L3 cache and 24MB of L2 help keep those workloads fed without constantly hitting system memory.

The AMD Ryzen 7 9800X3D is the obvious rival. That chip is built for gaming, with its 3D V-Cache giving it a serious edge in frame rates. But it's an 8-core part, so it falls behind the 285K in heavily threaded workloads. The 285K's 24 cores and 24 threads make it the better choice for content creation, AI, and productivity. The trade-off is gaming performance, where the 9800X3D still holds the crown.

The other competitors in our database are mostly server or workstation parts, like the HP Xeon P67080-B21 and various Core i9 X-Series chips. Those are aimed at different use cases entirely. The 285K's server score of 76.4/100 shows it's not meant for that world. It's a desktop workhorse, not a rack-mount solution. For a desktop builder who wants top-tier single-thread and excellent multi-thread without jumping to a workstation platform, the 285K is the sweet spot.

At $840 USD for the CPU and motherboard combo, you're getting a lot of compute for the money. The 285K alone would typically cost more than most high-end desktop chips, and the Z890 Tomahawk WiFi board is a solid mid-range gaming board. For builders who need both parts anyway, this bundle makes sense. The efficiency gains mean you might also save on cooling and power over time, though that's harder to quantify upfront.

Compared to the competition, the value proposition is strong for productivity and AI work. The AMD Ryzen 7 9800X3D is a gaming monster, but it doesn't match the 285K's multi-threaded and AI performance. If your workload is rendering, compiling, or local AI, the 285K justifies its price. If you're mostly gaming, you might find better value elsewhere.

Intel's Core Ultra 285K is the kind of chip that makes you rethink what a desktop processor should be. It's built on Arrow Lake-S with a 3nm process, packing 24 cores split between 8 performance cores and 16 efficiency cores. That's a lot of silicon, and it's aimed squarely at people who do real work on their machines, think AI workloads, heavy productivity, and content creation. The 5.7GHz boost clock on the P-cores is unlocked too, so overclockers have room to play.

What's interesting here is the efficiency story. Intel is pushing this as a chip that runs cooler and quieter while still delivering top-tier performance. Our database puts its efficiency in the 97th percentile, which is genuinely impressive for a 24-core desktop part. The 125W TDP and 250W turbo ceiling suggest Intel is being more careful with power draw than in previous generations, and that shows up in real-world thermals.

This particular listing is a Micro Center bundle with the MAG Z890 Tomahawk WiFi motherboard. So you're getting the CPU and a solid gaming-focused board together. The board supports DDR5 up to 256GB and has an extended heatsink design, which matters when you're pushing a chip like this. It's a combo aimed at builders who want a stable foundation without hunting down parts separately.

If you're building a pure gaming rig, the 285K is probably not your best bet. The Ryzen 7 9800X3D will give you better frame rates in most titles, and it's often cheaper. The 285K's extra cores and AI features won't do much for you if you're just playing games and browsing the web. You'd be paying for performance you won't use.

Also, if you're on a tight budget, this bundle at $840 USD is a significant investment. There are cheaper options that will handle everyday tasks and light gaming just fine. The 285K is for people who need serious multi-threaded performance, AI capabilities, or top-tier single-thread speed for demanding applications. If that's not you, save your money.

If you're building a machine for serious productivity, AI experimentation, or content creation, the Core Ultra 285K is one of the best choices on the market right now. The single-thread performance is unmatched, the multi-thread is excellent, and the efficiency means you won't need exotic cooling. The bundle with the Z890 Tomahawk WiFi board is a convenient way to get everything in one shot.

For gamers, the story is more nuanced. The 285K is no slouch, but the Ryzen 7 9800X3D will give you better frame rates in most titles. If gaming is your primary use case, that's the chip to beat. But if you split your time between work and play, or if your work involves AI and heavy multi-threading, the 285K is the more versatile option. It's a chip that earns its price tag for the right user.
