Best cpu I’ve used or seen anyone I know use in many years.
Style: Processor
This is quite the beast of a cpu. Also I had no issues with building this pc vs last year when I tried to build a 14700kf rig. Needless to say I couldn’t get it to even load the bios endless memory issues regardless of the ram I used unless I went with small sticks which I wasn’t about to run another 32gb rig. My i7 3770kf ran 32gb and never had these issues. Long story short the cpu/chipset and bios don’t have all the crap issues I found with 12-14th gen’s and yes I even ordered a cheap i5 12500k or whatever just to try and bypass the issues and update bios but even that wouldn’t do it with three ram brands and two cpus on a x870 chipset asus tuf mb. Well I use gigabyte aorus wifi7 mb and 2 48gb of crucial ram with room to add two more. It’s a beast cpu and only issue I had was installing windows 11 since I had all my drives hooked up and found out it will split the OS partitions on other drives and break the install. Anyway I’d say I gained around 35-40% boot speed for loading the OS with my main drive being a m2 ssd. The bios is the only thing I see slowing the cold boot down to pretty much the same as my 3770kf build with a ssd. But that isn’t a issue loads stuff a lot faster. I highly suggest spending the money to just upgrade to this cpu vs trying to save a little with a 12th-14th gen i5/7. I’m pretty sure they got the i5 version of the ultra to just use my pc for more then just gaming. Audio production and recording ect. So I wanted a beast that I wouldn’t need to upgrade for another 10-12 years like my last one. ... show more

Fantastic CPU, But Be Mindful of Your Motherboard Choice
Style: Processor
First off, the whole purchasing experience was great. The seller was thorough and made sure I received the product in a timely manner, which is exactly what you want when you're excited to start a new build. I would definitely purchase this item again based on the processor's performance alone. This Intel Ultra 7 is an absolute powerhouse. It chews through everything from high-end gaming to heavy multitasking without breaking a sweat, and the combination of P-cores and E-cores makes the whole system feel incredibly responsive. Now, it's important to note that the only flaw I had during my entire build process was not with the chip itself, but with the MSI hardware I paired it with. I ran into some frustrating stability issues and had to wrestle with a few BIOS updates before the system would run smoothly. Once that was sorted out, the processor performed perfectly, but the initial headache was all due to the motherboard. So, while the Intel 265KF gets a full 5 stars from me for being an amazing piece of tech, I'd strongly advise anyone looking to build with it to do some extra research on motherboard compatibility beforehand to save yourself some trouble ... show more

Solid gaming cpu. Outperforms Ryzen 9 in several workstation benchmarks. Holds 130fps in 2k gaming using a 5070Ti

Great Choice
Style: Processor
I am so glad I upgraded coming from a 6 core AMD to this is like night and day pairing with a 5070ti was the icing on the cake.

A fast chip for dorm gaming
Style: Processor
This was the processor I bought for the desktop I’m building in my dorm, mostly for gaming after class and getting coursework done. I paired it with my existing graphics card, and games feel quick while I keep a bunch of browser tabs and school apps open. I tried a late-night match after a long lab day, and it ran smoothly without slowing down my other stuff. The 20-core setup feels like plenty for what I do. My small gripe is that it runs warm when I push it, so I had to spend more on a decent cooler than I planned. It’s been easy to use at my desk. ... show more

Great deal especially if you can find on sale
Style: Processor
I've read a lot of reviews about how this CPU is not worth it and under performs compared to comparable AMD CPUs especially for gaming -- and that's very possible if you are an extreme gamer -- but I've had no issues at all and is you can find it if sale like I did then I don't think you can go wrong with it. I've played CoD BO7 and Battlefield 4 and done light graphics and video encoding work with no issues at all. ... show more

fast chip for my home build
Style: Processor
I bought this for a desktop build in my apartment, and I had to keep the budget in check since I’m renting and still paying for the rest of the setup. The 20 cores, with 8 P-cores and 12 E-cores, handle my everyday work and gaming without feeling sluggish. One evening I had a game running while I kept a bunch of browser tabs open, and things stayed responsive. The mild letdown is the KF part: it has no integrated graphics, so I needed a separate graphics card before I could even get a picture on screen. Make room for that cost when planning a build. ... show more
