Ryzen 9 3900X

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

Average Bench: 89.7% (35th of 1244)

Based on 77,262 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 which can impact gaming. 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]

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.

For what it is made for it does its job very well. 12 cores with strong clockspeeds makes it great for server and multitasking jobs.

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.
