Great Upgrade from 9900K
5 Stars
Great Upgrade from 9900K
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.

5.0 out of 5 stars A Powerhouse of Performance - Intel i9-12900K Exceeds Expectations!
Reviewed in the United States on November 14, 2023
Style: i9-12900KVerified Purchase
I recently upgraded my PC with the Intel Core i9-12900K processor, and it has been nothing short of a game-changer. The performance leap from my previous CPU is astounding. The i9-12900K handles multitasking with remarkable ease, and the speed is noticeable in everything from everyday tasks to more demanding applications.

One of the standout features of this processor is its hybrid architecture. The combination of Performance-cores (P-cores) and Efficient-cores (E-cores) is a brilliant innovation. It not only boosts processing speed for heavy-duty tasks but also optimizes power efficiency for lighter workloads. This adaptability is perfect for my varied use, which includes gaming, video editing, and software development.

 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.

5.0 out of 5 stars A performance Beast CPU
Reviewed in Canada on October 31, 2023

This CPU has 24 threads and 16 cores (8E cores and 8P cores) which really makes difference when dealing with 3d graphics and to prevent bottleneck issues

Doesn't cause a CPU and GPU bottleneck as I only get about 45% GPU usage and stay under 10% load in most AAA titles like Destiny or Call of Duty.

CinebenchR23 Benchmarks

Using CINEBENCH R23 I got a score of 27552 which is roughly 70 % of top performing CPU score of 43640.

Using Geek Bench 6 test

I got a Single core score of 2601 which is roughly 83 % of top performing CPU score of 3097 And a multi-core score of 12821 which is roughly 56 % of top performing CPU score of 21742
