Based on 6,650 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 is setting a new standard for high-end workstation processors. This is AMD’s first Ryzen 9 processor and is a 12-core, 24-thread CPU based on their latest 7nm Zen 2 microarchitecture. A second Ryzen 9 CPU in the form of the 16-core, 32-thread 3950X is expected around early Q4 of 2019. 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 relatively accessible launch price of $499 USD. By comparison, Intel’s coolerless 12-core, 24 thread i9-9920X is currently available for $1200 USD which is well over twice as expensive as the 3900X. Early benchmarks illustrate that the extra dollar spend does not translate to extra performance, with the i9-9920X having just a 4% greater peak overclocked benchmark than the 3900X across single, quad and multi-core workloads. Currently in terms of 64-core performance at this price point, there is no threat from Intel. The only real competitor is the upcoming 16-core, 32-thread 3950X ($749 USD) or possibly the slightly more affordable (but significantly worse value for money) 8-core, 16-thread Ryzen 7 3800X ($399 USD) which sits just below in the new Zen 2 line-up. 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]

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

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.
