Customer Ratings & Reviews

I recently dropped an i9-12900KS into my new build, and honestly, this CPU has blown me away. I’m running it with an MSI MAG Z790 Tomahawk board, 64GB of DDR5 6000MHz RAM, and an Asus Prime RTX 5070, all inside a Lian Li O11 Dynamic XL with a 360mm AIO. Even under heavy gaming, multitasking, and some light video editing, this thing doesn’t flinch. Temps stay solid, clocks stay high, and it feels like the system always has extra headroom. I expected it to be fast, but the overall snappiness surprised me more than anything. What really sold me is how consistent the performance is. No weird dips, no throttling, no drama - just raw, reliable speed. For anyone building a high-end rig who wants a CPU that can handle pretty much anything you throw at it, the 12900KS still holds its own extremely well. I’m genuinely impressed with how it pairs with modern GPUs and how smooth the whole experience has been.

Great quality and performance for the price. Reliable, easy to use, and definitely worth recommending to others

What a chip good for me it runs like a champ god bless

Great item. It's a bit overkill if you're just going for gaming, however, as someone who spends a lot of time in things like the adobe creative cloud, and in general, has a lot of different things happening on my computer all at once, it's a VERY powerful chip, and I can testify it's more than any regular person is going to need. Heat-wise, it's very good. I average about 45-50 degrees celsius during normal use. For reference, I do have a Corsair AIO cooler, so it might get hotter with a standard fan. Speaking of fan, it does not come with a stock cooler, so if you're building a pc and don't have a cooler for this, you'll probably have to shell out a little more. Installation is as simple as it can get.

Very happy with the speed. Once I turned down the voltage to the CPU I was able to keep the unit cooler by 25 degrees Celsius and not suffer any blue screen issues on full load playing games at over 100 frames per second. I believe my stock setting was at 3.36 volts and I reduced it to 3.155 Volts. Only do this once you understand how to safely modify this, and I also suggest not to over clock this CPU even though you can. Plenty of educational video available on YouTube on these topics with the Intel 12900 model CPU’s.

The Intel Core i9-12900KS is a powerhouse, boasting 16 cores and 24 threads with speeds ranging from 2.5GHz to an impressive 5.5GHz Turbo. Installation is straightforward, making it accessible even for those new to building PCs. Performance-wise, it's incredibly fast, handling demanding applications and multitasking with ease. Ideal for gamers and professionals looking for top-tier performance.

This goes well with my asus motherboard. Overall happy

Pricey but the best performance out there. I was lucky enough to get an SP94 (Asus Silicon rating system) so an above average chip but compared to the 12900k I already had it wasn't enough to justify its cost. I achieved exactly +1 bin better (100mhz) overall using an Arctic Liquid Freezer II 420mm AIO over my SP91 12900k for day to day use (5.2 all core vs 5.3 all core). Both thermal throttled into oblivion at 5.4 all core and at that stage you will need custom water and a potential delid for both to tame their heat output. I will say having 2-3 cores clock to 5.7 for single CB23 runs and gaming was nice to see but really made no real world difference when gaming and only a slight benefit versus my 12900k for compile times. So who is this chip for? If you're a new buyer and want the absolute best of the best and cost is no object and you don't mind a lot of power consumption and heat to potentially manage, this is the one for you. If you're into benching and overclocking and have the proper cooling to tame (or at least try) this monster chip, this is definitely for you. You will be cutting edge, state of the art and have the fastest consumer CPU on the market. On the other hand, if you want to save a little coin, give your cooler fans a break and have a quieter running system that runs cooler and get the same thing running slightly slower get a 12900k or even better a 12600k if all you do is game.

Fast and reliable. Love it while playing games. Awesome graphics

Easy to install and is very fast. Great product. Got it on sale!

Ordered for a custom AI build, got an amazing price. Wonderful results.

my sample has asus sp score of 100 on the p cores and 86 on the e cores. Using just the AI overclock and an AIO 3 cores @ 5.7ghz and all core of 5.4ghz. Temps stay within Intel spec. 6800mhz cl30 ram after overclock. IF you are going to buy a 12900k mine as well get a good sample. I had 5 other 12900k and none of them were close to this KS which in terms of KS's is mid range. Fastest chip for the next few months. Don't buy what you cant easily afford. Especially when it comes computer parts.

No issues or visible problems, processor runs in computer as advertised.

This revitalized my computer, it's been a night and day difference.

Top tier central processing unit for high end gaming requirements.

Great value and great performance. Sale prices are why I bought this

I use my PC for digital art and 3d rendering and it works flawlessly.

Excellent performance , however needs watercooler at least one with 360mm radiator

Runs what I need to exceptionally well. Got it on sale

Great Leo was or for the money pared it with the hard drive
