AMD Ryzen™ 9 3900X, AM4, Zen 2, 12 Core, 24 Thread, 3.8GHz, 4.6GHz Turbo, 64MB L3, PCIe 4.0, 105W, CPU OEM is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from does what it says runs warm between 40 and 50 degree c with NZXT kraken Z73, 360mm hasnt gone over 56 and had multiple games running and streams and video's its a monster of a cpu and worth every penny :)

Rated 5 out of 5 by from Great bit of kit Gone from an overclocked i7 5820 to this and it leaves the old chip in the dust. It's nearly halved time to encode H264 MP4 files and my machine feels far more responsive. Games running great as well. I got this with a 1TB Firecuda M2 drive, put them in a ROG X-570 Strix E with 64gb of RGB Corsair 3200 ram with my old EVGA GTX1080ti, Corsair H115i dealing with the cooling. I am well pleased, would reccomend this CPU, think I might need to get a new GPU to put the finishing touch to this build...

Rated 5 out of 5 by from Its All About The Cores Having always been from the Intel camp,time for a change,pleasantly surprised at the outcome.CPU temps at idle 33 degrees,Going back to my trusted brand,Noctua NH-D15 SE AM4,from a corsair h100i v2,a lot more quieter than the AIO cooler.
Date published: 2020-06-09
Rated 5 out of 5 by from Awesome this blew me away I upgraded from a pentium I7 made me feel like I`d been living in the dark ages. Price is ok but Im sure prices will drop when covid is finished. Its still worth what I paid for it and no sighn of Intel who are about a light year behind, Well done AMD
