Blazing-fast desktop CPU for creators + heavy multitasking (platform upgrade required)
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.

Thx for CU-DIMM compatibility! Good chip!
This CPU is easy to like bc it’s chill. Truly lol Great stable performance without being hot enough to fry an egg. Pair it with CUDIMM 8000mt/s and a Z890 board for best results.

Very capable and energy efficient processor.
This crushes anything I can throw at it. I'm amazed with how efficient it is and with a proper cooling setup, how cool it runs compared to my (very) old 7700k. I'll have to try overclocking it soon, but even at stock power, it's a beast.

A step up in several ways from 13th/14th gen Intel
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!

good quality
It is a great processor

Loving the New Ultra Series
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.

Excellent processeur, stable et performant dans les applications de productivité mais aussi en jeux, bien aidé par les derniers microcodes d’Intel et les optimisations des firmware de carte mères. Bien moins energivore que les générations précédentes Raptor Lake. Contrôleur mémoire bien mieux optimisé.

This is my first 9 core processor, and it's a beast! Doesn't heat fast, stable, and was easy to install. Great performances

Wat kun je hierover zeggen? Lekker snel, wel prijzig, maar dat weet je op voorhand. Het is de bedoeling de pc te gebruiken voor AI.

お値段しますので当たり前ですが、以前AMDX1950。32コア使用していました。 こちらのUPUは24コアで1/3の時間でエンコードなどこなしております。 ソフトにもよりますが、AVIUTL使用ならこれベストですよGPU使えないのでw

This CPU is a beast, It can run a 84b LLM just on the chip.
