Core Ultra 9 Desktop Processor 285K - 24 cores (8 P-cores + 16 E-cores) and 24 threads - Up to 5.7 GHz unlocked - 40 MB Cache - Compatible with Intel 800 series chipset-based motherboards - Inte

Upgraded to the Intel Core Ultra 9 285K for a new desktop build and it’s been an awesome “do-everything” chip. The hybrid layout (24 cores: 8P + 16E) keeps the system feeling snappy even with a lot going on at once, and the high boost clocks (up to 5.7 GHz) make everyday work and bursty tasks feel instant. What I like: Serious throughput for demanding workloads (editing/encoding, compiling, VMs, multitasking) Unlocked if you like tuning Integrated graphics is handy for troubleshooting or a no-GPU setup What to know before buying: This is LGA1851, so it’s a new motherboard platform (not a drop-in upgrade for older sockets). Power can ramp up under heavy loads (rated 125W base / up to 250W turbo), so plan on solid cooling and airflow. Intel Many listings don’t include a cooler, double-check what’s in the box. Overall, if you’re building a high-end desktop and want top-tier all-around performance, the 285K is a beast.

Works as should. Top tier CPU. I’ve always been partial to Intel CPUs. Lately I’m not gonna lie AMD has had me comparing but in the end Intel kept me as a customer. I may have considered AMD if it were substantially cheaper. Then it’d be substantial savings with comparable performance but that was not the case I found. Still not sure why they didn’t make an Ultra 9 285KF. Not really much else to say haha.

Not sure what to say.... Intel Core Ultra 9 285K (Arrow Lake family) is the newest Intel processor, released at the end of October 2024. According to Wikipedia, it uses a a variety of new production and packaging technologies, and for this reason it no longer follows the standard Intel generations and numbering of the type i5, i7, i9. Reportedly, it consists of at least 4 chips, all build by TSMC (the CPU itself is built using TSCM's cutting edge N3B technology, which Intel cannot built itself so far, while Intel does the last step, packaging of all chips on an interposer. Intel sees this technology as a blueprint for future generations of CPUs, and the new socket, LGA1851, is a new development which Intel, according to the trade publications, plans to use for several future generations. Hence, in terms of upgradability of CPU on an existing motherboard, it seems to be the best bet across Intel CPUs. High performance and relatively low power are main features of this CPU. This particular package includes on CPU itself, but no thermal paste and of course no cooler. Very easy to drop into the socket. Excellent speed. Intel's design, TSMC's leading edge manufacturing.

Excellent Processor, especially for people who do more than just game on a PC. (I do also game & it shreds 1440 resolution-2K gaming, paired with a 5070 Ti Graphics card) . I put it in a full-size computer case that has good air flow & with a $98 liquid cooler (360mm AIO ) and at load it never reaches 60C. So if you build the computer correctly, heat is not an issue. These Intel Ultras run efficient and cool if you build the computer the right way.

Every year I build a new pc based on the best components available,last year It was amd but this year i went intel,and so far it’s been interesting,this year amd components are twice as expensive,i went with the msi unify x 890 motherboard and it turned out to be defective,so i returned it and purchased an asus 890 hero motherboard which i really like,but the dvi cord was defective and i thought my 4090 graphics card was defective!!! Then my asus aio water pump didn’t work,i went with a Noctua air cooler, i wondered what the heck is going on!!! I finally got it all to work,really well i might add,i love the intel ultra 9 285 processor,im able to use G.skill cudimm 8400 ram,it works flawlessly,the pc wasn’t what i had planned but turned out to be better than I had planned,so far I’m really pleased with it,but it’s definitely the last pc I’ll ever build,should I have built another amd pc instead,not on your life!!! The intel codes didn’t work though for the free games

I am a programmer who works with compiled programming languages in a large codebase all day long, and I bought this processor after seeing it at or near the top of many compiler benchmarks. Indeed, this processor cuts through my work like a knife through hot butter, and it is a joy to watch it speed through tasks! And unlike previous generations of Intel processors, it is quite easy to keep it cool even with cheap air coolers. Despite minor overclocking, the processor stays 10-20 °C away from thermal throttling even under hours of the most intense stress tests (like Cinebench). Furthermore, the processor has been quite stable for me, as I have not encountered any crashes. Keep in mind that many of the mixed/negative reviews are focused on gaming, where the gaming performance for the price is quite disappointing. If Intel manages to iron out all of the major issues (a very big if), this processor will exhibit gaming performance similar to an i9-14900K while being significantly-more power efficient. Accordingly, this could be a strong mixed gaming/productivity processor in the future, but in the meantime, I would not buy this processor if having top-tier gaming performance is important to you. For productivity-focused users like me, however, I would highly recommend this processor for many productivity tasks, where it is often the fastest consumer-grade processor ever made.

I use this CPU in my gaming and video editing PC and it's honestly a step up from my 13th gen PC. Intel i9 CPUs have always run hot and the Core Ultra 9 is no exception. However, unlike the 13th/14th gen CPUs, you don't need a crazy cooling setup to keep it tamed under both light and heavy load(though for the sake of longevity I would still get at least a 360mm AIO or a 420mm AIO). Even a giant tower cooler like the Noctua NH-D15 Gen 2 will keep this CPU cooled properly. I don't do any heavy OCing, but the only high temps I see are during heavy rendering or compiling shaders for games(which this CPU does VERY quickly). I've used both the Core Ultra 7 and Core Ultra 9 CPUs and unless you really need the extra amount of horse power, the Core Ultra 7 is a better value than the Core Ultra 9. Stability is also easier to achieve on this CPU thanks to it's incredible memory controller. However, you really won't realize this unless you use RAM that has a clock driver in it(Known as CUDIMM), because if you're not you will not see the speeds intel claims you can hit, and if you can hit it, gets very unstable. Installation is straightforward and the same across 1200, 1700, and 1851 sockets so there isn't much to mess up. I'll say again; you will not see the high memory speeds unless you get a CUDIMM RAM kit. Conclusion: Basically only a small step down from the previous generation, but you get so much more stability and it is way easier to cool than the previous generations. Early reviewers made it sound like you were buying an i5 processor in a i9 branding, but man is it so misleading. This CPU absolutely performs like its previous powerhouse generation. BONUS: If you already have a LGA 1700 cooler you're in luck; you can reuse it on socket 1851! the socket dimensions are identical!

As expected. Nothing special, but as advertised. I would buy this again.
