Intel Core Ultra 7 265K: A Solid Comeback That Del
I've been running the Intel Core Ultra 7 265K in my main rig for a couple of months now, and honestly, it's been a pleasant surprise. Coming off the rocky Arrow Lake launch last fall, Intel has rolled out BIOS updates and driver tweaks that have turned this chip from a bit of a letdown into something genuinely capable. At $400, it's positioned as a mid-high-end workhorse, and for me, it's hitting that sweet spot between gaming muscle and productivity power without breaking the bank. Let's start with gaming, since that's where I spend most of my time. Early reviews hammered the 265K for underwhelming frame rates compared to AMD's X3D chips or even Intel's own 14th-gens. But with the latest updates, especially the microcode fixes and optimized schedulers, it's finally pulling its weight. Paired with an RTX 3080 at 1440p ultra settings, I'm seeing smooth 120+ FPS in titles like Starfield, DayZ and Dune Awakening with minimal stuttering. The integrated NPU helps with upscaling and frame gen, making DLSS feel snappier than on my old setup. Where this CPU really shines, though, is in the multi-threaded grind. With 20 cores (8 performance + 12 efficiency) and 28 threads, it's a beast for compiling codebases or rendering videos. I do a lot of freelance video editing in Premiere, compressing any videos at all used to choke my i5-12600K but now it flies through in half the time. Benchmarks back it up, it's edging out the 14700K by 15-20% in Cinebench multi-core and Handbrake encodes, all while sipping less power. If you're into content creation or dev work, those extra threads make a tangible difference without the bloat of a full 285K. Comparing it head-to-head with the 12600K, which I upgraded from, the 265K feels like a supercharged V8 engine. It's not perfect, single-core speeds can lag in older games, and you'll want a solid Z890 board to unlock the full potential. Overall, if you're building or upgrading in 2025, the Core Ultra 7 265K is a smart pick. It's not the undisputed king, but Intel's iterative fixes have made it a top-notch all-rounder that's punching above its weight. Solid value, no regrets here.

Excellent all around CPU
Lots of hate for these Core Ultra 2 processors, but, I have found that they are fine. I spent a year in the AM5 platform reading about how its the best thing ever... but, I disagree and I wont get into all the issues and oddities of that platform. What I will say is that this CPU runs great for productivity oriented tasks, its extremely easy to cool and memory as always is a strong suit for Intel chipsets. People look past the fact that this processor does amazing in productivity and is on par with with processors that have twice the threads (Intel no longer does hyper threading) and when you see how much work it can put in with half the threads going, its pretty impressive along with being very easy to keep cool. The ITX boards available for Core Ultra 2 are insane as well. Gaming has been wonderful as well... compared to my AM5 days, way less dips and more consistent frames. Mind you I am not saying my Avg is higher than my AMD, but the lows are way more consistent and it feels better and smoother. Love the added PCIe lanes so it keeps the bifurcation easier for builders and just overall better for people. Yes, Intel had a bad launch... but, they admitted all the faults and took ownership of how that launch went. With the Windows Updates, Firmware Updates this processor is a beast and people are sleeping on it because there is so much hype on team Red. Is it perfect... absolutely not... but this feels like Core Duo all over again. Its going to get better and better.

Core Ultra 265k FTW
Great productivity CPU and amazing for gaming tied with an RTX 5070 ti. Stays cool at around 34c at idle and under full load with testing spikes to the hottest at 84c with 20 minute stress test’s.
