The flagship of AMD's new Ryzen 3000 lineup is the Ryzen 9 3900X, which is a 12-core, 24-thread monster. Never before have we seen such power on a desktop platform. Priced at $500, this processor is very strong competition for Intel's Core i9-9900, which only has eight cores.

12-Cores; 24-Threads in a desktop platform; Beats Core i9-9900K conclusively in multi-threaded applications; Gaming performance significantly improved; 10% over previous generation; Outstanding multi-threaded power efficiency; Unlocked multiplier; Supports existing AM4 motherboards; Much bigger L3...

Still not as fast as Intel in gaming; No integrated graphics

The AMD Ryzen 9 3900X is the best mainstream processor on the market right now. With multi-threaded performance that destroys everything in its path and the inclusion of PCIe 4.0, you can't find a better processor without stepping up to the HEDT market.

Incredible performance; PCIe 4.0; Beats Intel at same price

Included heatsink may not be enough; Single core performance still behind

This is the most expensive CPU I've ever owned, and I don't regret buying it. It deals with everything I throw at it easily and I have not felt any issues so far. The Prism cooler is a bit noisy, especially at under load so I would recommend a decent AIO because the chip does run quite hot.

Watch out, Threadripper; take cover, Core i9! AMD's new top-end mainstream CPU for gamers and content-creating power users is the $499 Ryzen 9 3900X, and it's brute force in silicon form. This third-generation, 12-core Ryzen processor, based on the same AM4 platform and socket as earlier Ryzens, refines the standout features the Ryzen brand is known for, including power efficiency, simple overclocking, and very competitive performance per dollar. Despite its new name and guts—this is the first CPU to bear the "Ryzen 9" moniker, and one of the initial wave of Ryzen 3000 CPUs to support the Zen 2 microprocessor architecture—it's an evolution of AMD's consumer CPUs, with core features similar to its first- and second-generation Ryzens. That means it's an excellent choice for PC-building enthusiasts and upgraders. It's not markedly better in use case than Intel's comparable Core i9-9900K, but if you need all the cores and threads you can get, it's a superb, Editors' Choice value amon...

With more cores and threads than its chief like-priced Intel competitor, AMD's Ryzen 9 3900X is an excellent 12-core beast of a CPU to power a high-end gaming rig or a multimedia editing station.

Superb price-for-performance ratio in multithreaded scenarios; Among first consumer CPUs to support PCI Express 4.0; Relatively low power consumption; Huge L3 cache; Easy overclocking tools; Includes attractive cooling fan

Single-core performance and 1080p gaming a touch behind on some benchmark tests; No integrated graphics

Purchased 10 days ago. Using stock cooler, with no overclock, the CPU multitasks very well, and so far has performed fine in video-related work. I had no assembly problems or memory issues, which is/was a particular issue with past Ryzen versions. The price is high. So, if you don't want to do anything with video, or other heavily-threaded applications, choose something cheaper. I do want to record and edit video. An i9 9900k doesn't come with a cooler, and is apparently worse at heavy multi-threading work (2/3rds the cores, so not that surprising). The 9900k's higher per core frequency is useful for high-refresh games, but it's b...view more

Unbeatable for its price range, great cpu for gaming/video editing work. Would recommend

It is a product that totally changed the impression of AMD in my mind. Great performance at a much lower price compared to Intel. Really happy with the purchase.

Top notch CPU, has my other Intel CPUs beaten by miles! Cooler is well done as well.

New King is here. best of the best.
