    • Best cpu hands down
Style: i9-12900KS

Fastest cpu just a few years ago and still in the top of the class, it's only 5% slower single core than a 13900k with no microcode/oxidation problem. Runs way hotter than my i5 haha but with a good 360 AIO it runs nice and cool. So happy I have good integrated graphics for back up if anything happens to my GPU and can still light game. Its perfectly compatible with my z690 mobo just swap and play with added contact plate a must if you dare. ... show more

    • Overkill for me and Most.
Style: i9-12900KS
This started a new PC build for me when it was on sale for $320. I haven't built a PC since 2007, so it has changed a bit since then. This thing runs hot at full load. Watch gamers nexus on YouTube. It will pull a solid 250+ watts running cinebench. I'm using an Arctic Freezer 2 420mm with a thermal grizzly contact frame and kryonaut, and it will load up to 80 degrees almost instantly without throttling but drop immediately to 25-30 degrees when the load stops. This is with ambient at 22 degrees. This thing is brutally fast, though, and in reality, outside of load testing it, I have rarely seen it go over 30% usage. The more recent i5 and i7 processors can more or less be equal in most use cases. i5 13/14600, i7 13/14700. This processor is still top-tier and will be for a few years to come. 12th gen i-series processors were a game-changer, the 13th-gen improved on them a bit with more e-cores, and the 14th-gen is looking like a stop-gap to the next big thing. You won't be disappointed; make sure to keep it cool. ... show more

    • Cool running CPU...
Style: i9-12900KS
I was skeptical purchasing this CPU. I read topics claiming it gets hot. That's BULL!!! If you know how to build, able to put the right parts together, may take some research to make sound decisions, this is one strong processor. I game, watch media, do design work, and video editing, and do extreme multitasking, and have not gotten a hiccup. People are ready to put down a product without doing their homework to make it run like it should, screw the benchmarks and skepticism. Build it right and the rest will speak for itself. I believe in high quality and this CPU stands up to it all in cool smooth running, and seamless tasking. I waited to make sure I'd speak up for it, and I stand behind it 100%. Great CPU. ... show more

    • Great CPU! Reliable.

Very good CPU - I literally run a server on it and have no problems whatsoever! Is good when multitasking and overclocking! Very stable too!

    • DDR4 or DDR5 that is the question
Style: i9-12900KS
Maybe I can complete the CAD/CAM/Rendering computer now. Originally conceived as 'the gaming PC', but now has been re-purposed as business class and RAM prices has EVERYTHING to do with it.

    • Downgraded from 14900k
Style: i9-12900KS
My 14900k kept crashing games and was unstable right out of the box. Downgraded to this and it's solid at least and saves me about $300. The FPS difference for my purposes (gaming) is very minimal (<10FPS) from all my tests.. and my computer actually works. Also got 6800MT/S RAM to work with this if you're in the same boat. Definitely going AMD on my next build after this headache though. ... show more

I didn't get the "fancy" wafer box, just a normal intel box. It is a decent BIN. 97 SP overall, P Cores 108, E Cores 79.
