IntelCore™ Ultra 7 Desktop Processor 265K 20 cores (8 P-cores + 12 E-cores) up to 5.5 GHz

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.

This is a fabulously fast processor which makes 8k edits a breeze. I have a 14900k on my office machine and will be upgrading that machine too, as this processor outshines it in every way. Highly recommended.

excellent speed

Excellent processor that use in my PC

The Intel web page about the 265K is wrong. It says 125W TDP, 125W PL1, and 250W PL2. The correct details are 125W TDP, 250W PL1, 250W PL2. What this means is the 265K will boost to 250W for longer than advertised. That means you need a good dual tower air cooler or 360 AIO.

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 ;)

sluggish, unstable, expensive and unimpressive!Unclear how these chips were delayed a year and still not fit for purpose!I thought all the issues and disappointing benchmarks were with gaming so brought it for work/daily tasksSent back and brought an AMD 9900x for better performance for slightly cheaper price

But this new cpu are slower then last gen they are just more power efficient so don't believe what they say do your research and you will see for yourself and this are very highly priced the issues with intell of late are seriously making me consider the new AMD x3d chip that will be coming out next month.
