So far this thing is great! I upgraded from the 9900K and this has been a noticeable difference. I’m still in the process of updating drivers and reinstalling some software. I haven’t done any overclocking so the Cinebench score and temps are straight stock settings.
After seeing all the info on how hot this thing can get I added the Thermalright contact frame. It was a breeze to install. I watched the Gamer’s Nexus video about this frame and followed their directions.
For the motherboard I went with a MSI Z690 MPG Edge Wifi DDR4 so I could reuse my current RAM. I had to order a LGA 1700 bracket for the NZXT Kraken X73 AIO. I ordered both the frame and the LGA 1700 mount from Amazon and both arrived fast and were exactly what I needed.
So far my temps are staying in the general range of my 9900K. I’m planning to do a little gaming this week with it so I’ll have a chance to see how it does under my daily use. I also do a bit of Premiere and After Effects so I’m looking forward to seeing how it works there as well.
Overall, this is probably way more processor than I NEED. I was still able to do what I needed to do with the 9900K. I built the 9900K in 2020 during the height of the astronomically high PC price wave. I ended up getting this processor for about $100 less than I paid for the 9900K two years ago. So the price-to-performance upgrade for me was a no brainer.
If you want a fast processor at a reasonably decent price, this is a great one to get. Just be aware you will need to pay attention to your cooling.
Great Processo
This is the best Intel processor I’ve ever purchased and would not hesitate to buy another. It goes through my video processing like a champ and temps stay in very stable range never approaching hot.I’ve multi tasked it and it performs pretty well with that too.
So many options in CPUs this is a well received gen, blisteringly fast. I got the K because I have 2 monitors, onboard GPU renders my secondary so my RTX can render my main at max. Temps have been great with a 360aio, haven’t see it much above 45C when it’s chugging. For my games it’s been around 30-38C
all wat I needed for the next coming 5 years
I purchase this CPU 1 year ago and it cost me 74,000 JPY back then.
the price didn’t drop much since that time and the performance is satisfying so far.
the new generation spec is higher so if you want to buy this CPU don’t. instead, you can buy i7 Gen13 as it will have the same spec plus a better cache than the 12 Gen.
it might be better to buy the K version in case you have issues with your GPU to troubleshoot.
Glad I got this, it was on a sale on prime day for 250 so great value. It’s fast and has ran everything super smoothly. If I’m not gaming it only uses 10% and if I am video and audio editing it uses 15%. At most so far it’s used 30% on basic games. I can’t wait to start playing COD and ark on this when my GPU arrives.
It passed all stress tests and will be able to handle anything I will be throwing at it. Easy to install and worked well.
The temp, paired with my thermalright aio is staying under 30c with minimal usage and is averaging 47 high usage. The in the stress test it only reached 56 running max capacity.
It’s running stabely.
Would recommend if you get it on a deal, but go for an i7 12700k, most people won’t need an i9 power even for gaming. But like in my case if it was the same price as the i7 then by all means.
I posted a video of my build on YT named: Carisneat123 | First PC Build | goodbye low fps gaming
If anyone is interested in the parts I used with it, unboxing, installation, tests, game fps, and temps.
The Intel Core i9-12900K is an absolute powerhouse. With its hybrid architecture of performance and efficiency cores, it strikes the perfect balance between raw power and energy optimization. It’s ideal for both high-end gaming and demanding workloads like video editing, 3D rendering, or heavy multitasking.
In gaming, it delivers extremely high FPS and incredible smoothness, especially when paired with a strong GPU. For productivity, the improvement over previous generations is immediately noticeable—heavy applications run faster, and multitasking feels effortless.
Overclocking is stable and offers great headroom for enthusiasts who want to push it further. Plus, with support for DDR5 and PCIe 5.0, it’s clearly a future-proof investment.
Overall, the i9-12900K is a high-end processor that easily exceeds expectations for gamers, enthusiasts, and professionals alike. A true performance beast!
I recently got my hands on the Intel Core i9-12900K Desktop Processor, and I have to say, I am blown away by its performance. This processor is an absolute powerhouse, with 16 cores (8P+8E) and speeds of up to 5.2 GHz. It’s also unlocked, which means I can push its limits even further if I want to.
Installing the processor was easy enough, although I did have to make sure my motherboard was compatible with the LGA1700 socket and 600 series chipset. Once I had everything set up, I fired up my favorite games and applications to see how the processor would perform.
The results were nothing short of impressive. The i9-12900K chewed through every task I threw at it with ease, from demanding video editing software to the latest AAA games. I was able to multitask without any lag or slowdowns, and my system felt incredibly responsive and snappy.
The processor also runs surprisingly cool, even under heavy load. I did notice a slight increase in power consumption compared to my old processor, but it’s a small price to pay for the sheer performance boost.
Overall, I am extremely satisfied with the Intel Core i9-12900K Desktop Processor. If you’re a power user or a gamer who demands the best performance, this processor is definitely worth considering. It’s not cheap, but in my opinion, it’s worth every penny for the sheer power and speed it delivers.
