Intel Core Ultra 7 Desktop Processor, 265K, 20 Core (8P Core + 12 E-Cores) up to 5.5GHz

This processor is working just fine in a new pc I have just built. This is new technology to me having just built legacy machines before. Although the new pc is capable of being a gaming machine I am just using it for normal business activity. I am using the intel graphics within the processor via the hdmi port on the motherboard and the quality of the image is superb. Installation was easy and I have used a water cooling setup with it. I'm not really stressing it so running temperatures are low and the noise level is so low I can't detect any even with 4 fans. It's pretty fast too so very happy with it.

Been running the Intel Core Ultra 7 265K in my new build for a while now, paired with an MSI Tomahawk Z890, 32GB DDR5 6400MHz RAM, and an RTX 5080, and I’ve got to say — this chip is seriously impressive. From the first boot, it’s been nothing but smooth. No random crashes, no odd temps, and everything just works. I’ve got Intel 200S Boost and XMP enabled, and it runs my RAM at the full 6400MHz with zero issues — no drop-offs, no instability. That’s rare these days. Performance-wise, it’s a beast. My Cinebench R26 multi-core score came in around 34,900, and Steel Nomad hit just over 9,000, all while temps stayed below 80°C. I haven’t even bothered with manual overclocking — it performs that well on its own. Gaming’s been flawless too. I mainly play Red Dead Redemption 2 and a few other demanding titles, and this CPU just flies through them. No bottlenecks, no stutter — just pure, consistent performance. What I really like is how balanced it feels. It’s got the power to handle anything I throw at it, but it stays cool and quiet the whole time. No drama, no noise — just proper stability and speed. If you’re building a serious gaming or high-end PC and want something reliable, quick, and efficient without needing to mess around too much, the Ultra 7 265K is a brilliant choice.

Great CPU especially at the discounted price I got it (260 euros). It completely smokes everything you throw at it when it comes to productivity or gaming workloads. I highly recommend it. Would have like a slightly lower power consumption but I guess having more cores doesn't help here. We need the competition in the cpu space so we should make sure Intel doesn't stay far behind compared to AMD sales wise.

Intel’s Core Ultra 7 265K is a bold step into the Arrow Lake generation, blending high efficiency with solid multi-core muscle. With 8 performance cores and 12 efficient cores, it’s built for demanding productivity tasks and moderate gaming, though it doesn’t quite dethrone the competition in every category. Performance Highlights: Boosts up to 5.5GHz on P-cores and 4.6GHz on E-cores, delivering snappy responsiveness. 30MB of L3 cache and improved L2 cache per core help with multitasking and heavy workloads. Great for rendering, encoding, and synthetic benchmarks—especially in multi-threaded scenarios. Gaming Caveats: While capable, it trails behind AMD’s X3D chips and even Intel’s own 14th-gen CPUs in some titles. Performance can vary depending on BIOS optimization and Windows scheduling—some games show noticeable dips. Efficiency & Thermals: Built on TSMC’s 3nm process, it runs cooler and draws less power than its predecessors. Stays under 85°C with a decent cooler, even under full load. Platform Notes: Requires a new LGA1851 motherboard, which adds to upgrade costs. Compatible with existing coolers, but benefits from faster DDR5 RAM and PCIe Gen 5 support. Some may see this as sub standard to the X3D CPU's but when you're running at high resolutions like 4K, the difference is not noticeable with modern GPU's (I'm running a 5080). For other tasks aside from gaming, this thing really covers all angles. Easy to install, typical for Intel.

Installed the Intel® Core™ Ultra 7 265K (20 cores – 8 P-cores + 12 E-cores, up to 5.5 GHz) in a recent build and it has been outstanding. This thing just takes everything thrown at it in its stride. Gaming? Effortless. Multitasking? Laughs at it. Background apps, updates, streaming, editing — it just keeps going without a hint of slowdown. The hybrid core setup works brilliantly. The P-cores handle heavy tasks, the E-cores mop up background processes, and the whole system feels incredibly responsive. Lightning fast is genuinely the right phrase here — it’s one of those processors where you stop thinking about performance because it’s simply not a bottleneck. Boosts up to 5.5 GHz feel properly snappy in real-world use, and it pairs beautifully with fast DDR5 and a decent GPU. Thermals are manageable with a solid cooler, and overall stability has been rock solid. If you’re building a high-performance desktop and want something that can game hard while multitasking like a pro, this is a fantastic choice. Five stars. Serious performance, zero drama. Exactly what you want from a modern CPU.

Fast for productivity not so good for gaming (until DDR5 CUDIMM of 8000 and higher become available at reasonable price). Great for video editing tasks. Personally I can't tell between 250fps and 300fps ;)

fast and stay cool. I had intel core with 20 cores ,it does good but go hot.,this one is faster on single core, games and tasks

Blistering. Upgrade from 8th gen i5 and it’s a different world. Amazing frame rate on Minecraft, even with built in graphics. Zipped through office work. Quick processing video. Probably overkill if you don’t game, or do video/audio editing. Really pleased with value for money. Really easy to fit into a Gigabyte z890

Tutto ok, molto veloce e stabile, non scalda molto

Worked Great, Thanks

I don’t usually write reviews, but I had to give credit where it’s due. I upgraded to the Intel Core Ultra 7 265K after using an older i7 for years, and the difference is night and day. This thing flies. Whether I’m editing 4K video, running multiple VMs, gaming on ultra settings, or doing 3D rendering in Blender — the 265K handles it all without breaking a sweat. What impressed me the most was the balance between power and efficiency. Even under heavy load, thermals are very manageable (paired it with a decent cooler), and it doesn’t chug watts like older high-core-count CPUs. The 20-core architecture is perfect for multitasking — I’ve literally had 50 Chrome tabs open, Premiere Pro rendering, and a game running simultaneously. No hiccups. Also, shoutout to Intel for keeping single-core performance top-notch. Games run crazy smooth, and frame times are tight. I considered going AMD for a minute, but honestly, this chip gave me the best of both worlds: high thread count and insane IPC. If you’re building a high-performance rig for creative work, content creation, or serious gaming — this CPU is worth every penny. It’s future-proof, it’s fast, and it’s shockingly efficient. 10/10.

新世代アーキテクチャに惹かれてLGA1851環境で新規に組みました。 前世代から効率が大幅に上がっているのを実感します。 ■ 良いところ ・優れた電力効率と低発熱: 驚いたのが消費電力の落ち着き具合です。 以前の爆熱のイメージが払拭され、しっかりしたクーラーを使えば静音で運用できます。 ・マルチタスクの快適さ: 20コア（8P+12E）の恩恵で、裏でアプリを複数起動しながら重いゲームをしてもカクつくことがありません。 ■ 懸念点・注意点 ・マザーボードの買い替え必須: ソケットがLGA1851に変更されたため、従来のLGA1700マザーボードは使い回せません。プラットフォーム移行の初期投資はかかります。

A great chip to use for content creation paired with nVidia 5th generation GPU.
