Ryzen 9 3900X

▲ 1241,875 ▼

12 Cores, 24 Threads @3.8GHz, Zen2.
Release date: Q3 2019.

Average Bench: 94.8% (9th of 1186)

Based on 18,565 user benchmarks.  Device: 178BFBFF00870F10 Model: AMD Ryzen 9 3900X 12-Core Processor

Early Q3 of 2019 welcomes the Ryzen 9 3900X, AMD’s current top of the range, third generation Ryzen flagship which raises the bar for 64-core processing on desktop CPUs. This is AMD’s first Ryzen 9 processor and it is a 12-core, 24-thread CPU based on their latest 7nm Zen 2 microarchitecture. The 3900X has a boost/base clock of 3.8/4.6 GHz, 64 MB of L3 cache (double the L3 on the rest of 3000 series), support for 3200 MHz DDR4 system memory and a TDP of 105W. All this, plus a Wraith Prism cooler, at a very reasonable launch price of $499 USD. By comparison, Intel’s 8-core, 16 thread i9-9900K is available for $479 USD (and requires a cooler: $30+ USD). Benchmarks illustrate that the overclocked 3900X leads by a whopping 41% for 64-core processing but that the 9900K maintains a 10% lead for gaming, desktop and other sub octa-core tasks. The 3900 memory controller is significantly improved over previous Ryzen iterations and shows a better write throughput than the lower spec 3000 models, but it still shows relatively high latency. In terms of 64-core performance at this price point, there is no threat from Intel. The only real competitor is the upcoming (Q4, 2019) 16-core, 32-thread 3950X ($749 USD). The Ryzen 9 3900X is compatible with the new PCIe 4.0 enabled X570 motherboard via an AM4 socket, as well as 400 and 300 series motherboards. [Jul '19 CPUPro]

Superior power in this piece of silicon. But I9-9900k(f) is better for now due to deficit of this cpu, and all we can do with that is wait until this deficit ends Upd. I heard that Ryzen 9 costs 500$ in some stores now. If you see it - buy it

Here you have AMD just about on par with the 9920X for 700EUR (!) less. Another great value chip.

Offering 12 multithreaded cores while using the consumer AM4 socket isn't an easy feat. This consumer multithreaded monster is faster than the preceding AMD TR 2920X in term of both single and multithreaded performance. However, you'll get lower amount of total PCI-E lanes than the preceding AMD TR 2920X but is balanced with use of the newer PCI-E 4.0 interface which is as twice as fast as the older PCI-E 3.0. For pure gamers, suggested to opt for Intel Core i9-9900K instead which offered better gaming performance and better overclocking headroom for your very high FPS gaming.

This site may be run by blatant Intel shills (as shown by their hypocrisy against trustworthy and reliable tech sources like Hardware Unboxed and Gamer's Nexus) but the 3900X is still the champion of 2019. 9900K is a joke with it's top-end cooler and Motherboard requirements not to throttle or have any chance of Overclocking, gets crushed by the 3900X in 8+ thread workloads and far better frame time consistency in Games. But of course that tiny single core apparently makes it lose to the 9900K. This isn't 2009, games are using 6-8+ Threads now. Get with the times.

What can I say? I want this CPU so bad. I plan on buying it once I graduate from college. I don't game as much as I used to, and mainly need a powerful CPU for Premier Pro, Lightroom, and Photoshop. I know intel is better at photoshop and Lightroom but with a bit of overclocking this is fine, and the premier pro performance is just so far ahead of 9900K

What a great time to be building a PC. AMD is showing Intel that complacency doesn't keep business, and users are repeating the benefits of this newly rekindled competition. If the 3900X is an indication of the next few years, Intel will soon be the one playing catch-up.
