Review: Intel Core Ultra 9 285K - 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.
Review: This processor is quite powerful. - Good processor, it's very powerful 🥵

### ⭐⭐⭐⭐⭐ This processor is quite powerful.
*by O***S on June 20, 2026*

Good processor, it's very powerful 🥵

### ⭐⭐⭐⭐⭐ A step up in several ways from 13th/14th gen Intel
*by C***S on July 10, 2025*

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!
