    • 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

    • 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

    • 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

    • The last, great Intel Core i9 standing.

In a world of AMD 7000- and 9000-series X3D and non-X3D CPUs, I just now chose to build a PC based on this Intel Core i9-12900KS. The logical question is "Why?" No good answer, other than part nostalgia and part brand loyalty: Intel has been a reliable partner in this computer building hobby for a long time. That said, previous PCs of mine were built using AMDs Phenom II Black and FX-8370 CPUs, so I don't consider myself a 'fan boy' of either brand. So why? Like buying an Alfa Romeo when a Toyota Camry is cheaper, more efficient, and more reliable, you buy the Alfa because you want it. And in this case, you buy this CPU because it's the last, great Core i9 standing and will turbo boost Pcores to 5.5 GHz at stock Intel power settings and without MCE. I love it already. ... 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.

    • Powerhouse CPU
Style: i9-12900KS
Have been using this CPU for over a year now, it's incredibly powerful and fast for gaming and video editing. It does put off a lot of heat though, I'd recommend using a 360 AIO to keep it cool.
