IntelCore i9-12900K Gaming Desktop Processor with Integrated Graphics and 16 (8P+8E) Cores up to 5.2 GHz Unlocked LGA1700 600 Series Chipset 125W

Was new in box as advertised. Haven't had any issues with it in the months since buying it. Been a great chip for gaming and productivity. Make sure you use a good cooler for this guy. I'm using an arctic liquid freezer iii pro 360mm a-rgb aio and it's keeping it at 61°c under full cinebench multicore test. Went with the 12th gen to avoid any of the issues 13th and 14th gen suffered from.

Still a workhorse, have it paired with an astral 5090 and it still impresses me. Have a z790 rog strix mobo that I originally had an i9-14900k but, the chip was bad and ended up doing an RMA with Intel. Received another, and needed to lower voltage etc... they said. I sold it to a friend. I did help him update his bios/lower the voltage/etc.. Everything I dont have to do with my I9-12900k because you know.... that defeats the purpose of having that. So why not the 13900... I saw reviews as well and it looks like Intel's issues started with that and only got worse with the 14900 so I just went to the reliable 12900. Anyhow, after the latest Intel proc disaster, I will be switching over to AMD procs unless Intel comes back with their next one in 2026 and it's a banger...

The Intel Core i9-12900K is an absolute powerhouse! With 16 cores (8 performance and 8 efficiency), it delivers outstanding speed, handling even the most demanding games and applications effortlessly. The processor can reach up to 5.2 GHz, and the unlocked features give you plenty of room for overclocking to boost performance even further.I am particularly impressed with its integrated graphics, which provide smooth performance without the need for a dedicated GPU for lighter tasks or when gaming at lower resolutions. Whether I'm gaming, streaming, or multitasking with resource-heavy applications, this CPU handles it all with ease.The LGA1700 socket and 600 series chipset ensure compatibility with future tech upgrades. If you're looking for a high-performance processor that can handle anything you throw at it, the i9-12900K is a fantastic choice. Worth every penny!

use it to build a new PC and it works great.

I've put together a few systems and run some retail 12900k chips so far and the 12900k is by far an amazingly fast CPU.Unfortunately this one I ordered from Amazon came already opened. As soon as I opened the shipping box I could tell it had been opened before. The edge was uneven and the label crease was loose. I put my X-acto Knife down (which is what you need or something similar to open these as the label is there for a reason) and with just the gentlest of pressure the label peeled away from the center where someone oh so nicely had finely cut the label horizontal to make it easy to fold one side back over the other and with just a quick once over it looked almost normal.If I hadn't opened a few of them already with Intel's fancy new packaging I probably would not have noticed but the way the packaging normally is, it is VERY precise, tight, even lines and you will not be easily or gently opening it up with a simple light finger pry.My biggest fear was there wasn't going to be a CPU in there at all but luckily the right CPU was in there that matched the container batch but if something is sold as new I don't do open boxes.Make sure to check your packages before opening. The seal should be nice and tight and straight. The edges of the back flap should be firm and secure against the other flap and the bottom line/edges should be even and exacting.Give a gentle pull on each corner of the box where the label keeps it sealed to make sure it hasn't been altered or tampered with. It should be VERY firm and unable to just pull open easily. Look at the condition of the box itself around that area and even the gold disk inside.Fresh, brand new i9 12900k's are very pristine and boxed with precision.Still, they are fantastic processors overall and a worthy upgrade from 10th and 11th gen.

The Intel Core i9-12900K is a beast for gaming and multitasking! With 16 cores (8P+8E) and speeds up to 5.2 GHz, it delivers incredible performance. Integrated graphics are a bonus, and unlocking its full potential is easy. Runs smoothly on LGA1700 motherboards. Highly recommended for enthusiasts—worth every penny!

I ended up having to do a new computer build after the G. SKIL RAM died (DDR4). The RAM was in an older computer that had an Intel 8th Gen Processor. I was hoping to just find a less expensive way out of upgrading, but between only being able to get motherboards and processors from China (Intel 9th, 10th gen), plus Windows 11 wasn't friendly with those gens of processors, I opted to bite the bullet and settled for this Alder Lake processor which was "processor of the year" a couple years ago on Tom's Hardware. I combined it with an ASUS ROG STRIX Z790Z-E motherboard, Crucial 4800mhz DDR5 RAM (that's what's recommended by Intel), a Noctua 120mm dual-fan air cooler, recycled Samsung solid state drives, and new case fans. The i9 processor in that configuration is very fast. For those that complain that the ASUS board has trouble accessing the internet, yep I did too. Turns out that I needed to use a laptop to download the Ethernet and WiFi drivers from Intel and a few more drivers, too. Also learned that my older RJ-45 cable was a problem so replaced it, too. Someone on the internet said that the i9K processor is so powerful having fewer RAM mhz doesn't matter, so I took the recommendation and saved some money without sacrificing performance. This will likely be my last build, so I bought a new Planteks case to put it all in. :)
