- Reviewed in the United States on May 3, 2025Style: ProcessorVerified PurchaseNot 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.
- Reviewed in the United States on May 3, 2025Style: ProcessorVerified PurchaseEvery 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.

- Reviewed in the United States on May 31, 2025Style: ProcessorVerified PurchaseHad 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.
- Reviewed in the United States on May 5, 2025Style: ProcessorVerified PurchaseVery 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 48GB
Beats 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.
- Reviewed in the United States on April 12, 2025Style: ProcessorVerified PurchaseUi9 285K, GB Z890 AE WiFi 7 MB, temporarily using integrated Intel graphics. After many builds, 30+ years, due to unavailability of the competitors top end CPU I decided on seeing what Intel had to offer. This was my first Intel CPU build and WOW, super efficient, impressive clock and core management. I like Intel's approach to splitting cores between efficiency and performance, perfect for a workstation, occasional gaming where CPU demand can vary substantially. Simple WS tasks, CPU is a 0-1% load, 1 GHz, many cores are parked or have zero load, CPU temp ~30-32C , speed bumps up in speed momentarily during app launch but doesn't stay there for long. Looking forward to linking this up with a nice GPU someday, that's if people would stop buying to scalp GPUs and they become available again.

- Reviewed in the United States on December 23, 2024Style: ProcessorVerified PurchaseI recently purchased it.
The product has significant issues that have rendered it unusable for my professional needs:
The processor exhibits shadows that appear to be damaged clusters.
Even when working solely with RAM, the processor cannot efficiently run structural design programs like AutoCAD. The performance is extremely slow, significantly hindering my productivity.
I am deeply disappointed with Intel's quality control on this product. Despite its high price and claims of being unlocked, it fails to deliver the expected performance and productivity.
- Reviewed in the United States on May 5, 2025Style: ProcessorVerified PurchaseIntel Ultra 285K is currently top of the line CPU from Intel supporting latest tech like NVME GEN5 and WIFI7. If you want top of the line performance from intel Ultra 9 285k should be your choice. Please keep in mind that Intel also has Ultra 7 265k which is more budget friendly but slightly slower in performance.

5.0 out of 5 stars Excellent performance with low temps
Style: ProcessorVerified PurchaseGreat 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.
- Michele CainiReviewed in Italy on May 29, 2025
5.0 out of 5 stars Wow, just wow
Style: ProcessorVerified PurchaseNo complaints about this CPU. To be fair, I jumped several generations and the improvement was crystal clear.
I use it mainly for work, where I need raw power, and it does not disappoint me. It also keeps up for the gaming part, despite the not so kind reviews.
Extremely fast and quite easy to tame, even with (actually beefy) air coolers. It sits just above 30 degrees at idle and hovers just around 80 at full load, even for sessions lasting tens of minutes at 100%.
I would recommend it, although not too warmly, given the recent news about a socket review coming soon on the Intel side.
Let's say it's a great CPU if you intend to use it for the next 4 or 5 years, and then change it together with the mobo. If instead you prefer to buy a mobo and run multiple CPUs on it in a few years, look at AMD.

5.0 out of 5 stars Excelente CPU "extreme"
Style: ProcessorVerified PurchaseEste es el procesador que debe tener tu PC si piensas ensamblar una nueva máquina de la plataforma Arrow Lake. Pienso que no le falta nada a este procesador, y realizando los ajustes y "tweaks adecuados" en el UEFI, se puede optimizar y potenciar considerablemente su desempeño. Es fácil de overclockear y funciona de maravilla con la nueva memoria CUDIMM.
