Personal preference paid off
Don't Worry when you watch you tube reviews; half of them take with a pinch of Salt. This Processor works well with intel's Super Boost that pretty much takes care of half the Bios settings, RAM running well CUDIMM @ 8000mts without issues. For Casual Gaming and other tasks fitted with a Crucial T705 its very fast, not had any heat issues or heat related Thermal throttles causing any Stutters, it Works well. High FPS on a 165Hrz 4k Monitor as expected, yes AMD can have an uplift in FPS so it Can be that team RED or Blue divide. Personally Heat, Power and reliability from this Core Ultra 9 is worth a loss of 10/20 fps in games. The Margin of AMD tends to Greater in 1440p. All-rounder PC then this is the Processor to buy it also has NPU, Future AI stuff. Early setups will potentially have issues if not updated to Manufacturer latest BIOS and Micro codes from INTEL. New Builds have these to hand, update the bios from flash drive prior to Windows install. less issues. Intel is releasing a refresh model prior to a new processor and chip set that is going to increase Gaming speeds but this Core 2 Ultra 9 if picked up at the right price should last for years. Half of the review for this are well out of date and Intel has done some wizardry to get it up to speed.

An impressive CPU for gaming and rendering
This CPU has greatly increased my productivity, it's speed and power is perfect for both heavy gaming and 3D rendering. I haven't had any stability issues with this CPU, and although anecdotal, neither has my friend with the same chip. Whilst very expensive, it doesn't feel quite as painful to the wallet purely because of how capable it has been. It does however need some beefy cooling. I use a Noctua Nh-u12a chromax cooler and sit at about 36° at idle, and push 65° to 70° under normal gaming usage; under heavy rendering it can reach 80° but it hasn't seemed to have throttled itself to intensely because of it. Pros: Great stability Fantasftic power Wide range of functionality Cons: Pricey Requires good cooling

Excellent
This chip is very quick without overclocking. I don’t benchmark or anything too strenuous, just play a few games, stream and work from my current build. This CPU is paired with an ASUS Hero Z890, Samsung 9100 PRO, 64GB 6400 CL32-39-39 RAM, and a 5080 Astral and boy does it fly!

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.

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.

The Intel® Core™ Ultra 9 285K delivers an outstanding balance of raw performance and stability. Installed on a Z890 motherboard, it booted up perfectly and instantly hit 5.7 GHz on the P-cores, while the 16 E-cores handle background tasks seamlessly. Whether gaming (Diablo IV, for example) or editing 4K videos, everything runs buttery smooth with zero stutter. Thermals are well-controlled — with a 360 mm AIO cooler, it stays around 70 °C even under heavy load. Power draw is high, but absolutely justified by the performance output. Multicore rendering, simulations, and compression tasks are completed incredibly fast. The new architecture and AI Boost really make multitasking feel more efficient and responsive. Overall, it’s like having the full desktop version of Intel’s Ultra series unleashed.

Great CPU when using the latest mobo bios, however the latest Intel 200S BOOST update thing is a useless gimmick. On the Asus Proart board, the XMS tweaked profile gives far better speeds and lowers the ram latency by 17ns which doesnt OC the CPU at all.

Está bien vrgs No se calienta y su velocidad es alta aún en renders 3D El embalaje está algo simple comparado con la serie i9 de la generación anterior, se entiende que son eco-friendly y eso Pero por el precio del procesador quizá una mejor protección no estaría de sobra. Fuera de eso es una maravilla.
