The 6 Best CPU for RTX 3080 Reviews

Intel has been losing a lot of market share and ground ever since AMD launched its 3000 series in 2017. The 5000 series by AMD was even a worse blow, and Intel had to do something to get back in the competition. They started to gain some ground with the 11th gen of processors after refining their 14 nm transistor size to the extreme. But it wasn’t enough, so they came up with a newer refining process which made their transistor size smaller down to 10 nm, also known as 10ESF.

The 12th gen of Intel processors, based on the 10ESF (Intel 10nm Enhanced SuperFin), packed some serious performance and were Intel’s answer to the severe beating they took from AMD over recent years. The Intel Core i9-12900K is the flagship processor of the 12th gen, dubbed the Alder Lake.

Intel had become complacent in the past, and the Core i9 12900K is the right innovation that was much needed to stay afloat in this highly competitive market. The processor has 16 cores and 24 threads and contains 8 performance cores and 8 efficient cores. The base clocks of the P and E cores have been rated at 3.2 GHz and 2.4 GHz, with boost clocks reaching 5.1 GHz on P cores and 3.9 GHz on the E cores, and it has a rated TDP of 125W. The chip can reach a Turbo Boost max of 5.2 GHz and, with this kind of performance, goes head-to-head with AMD’s Ryzen 9 5950X which is also a flagship processor.

The processor currently boasts the title of the fastest single core performance in benchmarks and can easily handle a high-end GPU like the RTX 3080 without breaking a sweat. It also has an integrated GPU, but you won’t need it since you’ll be running the discrete GPU. It also supports DDR5, which allows for even faster RAM speeds.

Before you buy this processor, a word of caution is that it tends to run hot. Being the K variant, it has ample OC headroom, so make sure you invest in an efficient cooling solution to fully take advantage of the performance it brings to the table.

We put this processor on top of our best CPU for RTX 3080 list because of its pricing and performance; however, as you know, it’s a flagship processor, so you need to spend enough cash on the motherboard and other components too.
