IntelCore™ Ultra 9 Desktop Processor 285K 24 cores (8 P-cores + 16 E-cores) up to 5.7 GHz

My latest build June 18, 2025 was an all blackout no ARGB workstation to run SolidWorks: Intel Core Ultra 9 285k, MSI MAG Tomahawk Z890E wifi motherboard, G.Skill Flare X5 DDR5 64GB 6000 MT/S, Samsung 990 Pro SSD 1TB M.2, Thermaltake Toughpower GF A3 1050 watts power supply, upHere 8x6mm heat pipes direct contact 280Watt TDP CPU air cooler, Corsair 4000 RS Frame case, Corsair RS 120mm case fan, and PNY Nvidia RTX 2000 ADA 16GB GPU.The first thing I did was to update the BIOS on the mobo. With nothing(no RAM no CPU) on the mobo I inserted a 32GB USB flash drive with the latest BIOS file on it into the BIOS flash USB port, connected the power supply 8-pin and 24-pin cables to the mobo, turned on the power supply and press the BIOS flash button on the mobo, and in about five minutes the BIOS update was done (the LED light went out). Assembled all the parts into the case. I applied a very thin and even layer of thermal paste to both the CPU and the CPU cooler. For air flow I did three 120mm fans intake in the front and one 120mm fan at the rear. This fans arrangement forces cool air to flow across the entire motherboard which cools the RAM, VRM, help CPU air cooler intake and the GPU.I ran Cinebench 2024 and Core Temp for a10-minutes multicore stress test. With all 24 cores running at 100% the temperature range for all cores varied from 73 to 78 with every now and then a couple of cores spiked to 82 on for a few seconds then came back down under 80 degrees. The 285k drew around 205watts during the stress test. Even all six fans (four on the case, two on air cooler) rammed up to 100% the whole system was not noisy at all. I let the system burnt in for 24 hours and not a single hiccup. The CPU was very stable, the temperature was low and the system was very quiet.The Nvidia RTX 2000 ADA 16GB GPU is not for gaming and this system was not intended for gaming but for work station doing CAD type program specifically SolidWorks.I did a similar system back in January this year with the same CPU and mobo and I must say I was and I am impressed by the performance, reliability and stability of the Intel Core Ultra 285K and MSI MAG Tomahawk motherboard.Final thought: In day to day real life working with SolidWorks the 24 cores of the CPU will hardly reach 100% capacity. This is an over-built quiet system with a lot of horsepower to spare and most importantly a stable system for professional work.

Why did you pick this product vs others?:You hear everyone online recommend the AMD 3d processors over this but that really is only true if all you use your pc for is purely gaming. If you also use it for streaming, creating content, workflow and virtual machines then this Intel processor is the way to go. I have had no issues with it but I would recommend pairing it with a three fan new generation aio cooler, my temperatures have been great considering.

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.

Every so often you find out Microsoft and Apple won’t upgrade the Operating Systems on your computers that you bought or built in the past. If you’re a Gamer or a Designer working with AI you want the BEST and FASTEST. Sometimes you have to compromise, a little, a 5080 vs. a 5090. But I don’t feel that I compromised on the CPU with this purchase. Glad I built my new beast before Tariffs impacted Foreign products.My build uses an ASUS Z-890 White Motherboard and a NZXT Kraken Elite Pro AI cooler. My one Recommendation is to secure your Intel i9 CPU using a Thermal Grizzly Contact Frame. The NZXT AI CPU mount does NOT provide adequate pressure for the Intel CPU chip, my PC would not boot.The AI CPU Mount that shipped with my Arctic Liquid Cooler III worked GREAT but I wanted the Kraken Elite Pro Display for CPU and GPU Temp feedback.

Had to minimize core use with Folding at Home. The chip is much faster than my old Socket 2011 system, which was much faster than the SW Engineering systems we use at work (large fed gov SW work) but this 15th gen i9 just doesn't slow down.Even the Arctic Liquid Freezer 3 (with 3x140mm) is taxed to keep it cool and that cooler has high ratings.

Very fast CPU once paired with high-end ram and overclocked. By default not all that revolutionary!5.6p, 5.0e, D2D 40, NGU 35, Ring 4.2 GHz, DDR 8000.Memory bandwidth: 128 GB/s 48GBBeats even the 7950 and 14900K in some workloads, but any CPU in the last gen with faster clockspeed will be better for games.... this is faster than the Raptor Lake for CPU based rendering etc.It can OC even more than I have set, but heat is becoming a issue for my AIO at such high loads and benchmarks.It only runs hot when benchmarking or stress testing, under normal gaming it doesn't sweat at all, under idle-like temps. Crazy.

fast, relieble, I recommended for all professional video editor, graphics designers.

Does the job well, but a couple things to keep in mind.1. Make sure to update your BIOS or else you have issues w/ this CPU and MB.2. It does not have Hyperthreading
