AMD Ryzen 9 3950X - SANDRA, PCMark, And Geekbench
The AMD Ryzen 9 3950X
When the Windows installation was complete, we installed all of the drivers necessary for our components, disabled Auto-Updating and Windows Defender, and installed all of our benchmarking software. When that process was done, we performed a disk clean-up, cleared any temp and prefetch data, and optimized all of the SSDs using Windows' built-in utility. Finally, we enabled Windows Focus Assist to minimize any potential interruptions and let the systems reach an idle state before invoking a test.
Also note that throughout testing, we ran numbers on the Ryzen 9 3950X in both its default 105W TDP mode, and in its 65W "ECO" mode. With the latest edition of Ryzen Master, the additional lower-power ECO mode is available with some of AMD's Ryzen 3000 series processors.

We began our testing with the latest version of SiSoftware's SANDRA 2020, the System ANalyzer, Diagnostic and Reporting Assistant. We ran four of the built-in sub-system tests that partially comprise the suite with the Core i9-9900KS (CPU Arithmetic, Multimedia, Cache and Memory, and Memory Bandwidth). All of the scores reported below were taken with the CPU running at its default settings, with 16GB of DDR4 RAM running at 3,200MHz, in dual-channel mode, on the MSI MEG X570 Godlike motherboard.

In the GeekBench test, we're stressing only the CPU cores in a system (not graphics or GPU architecture), with both single and multi-threaded workloads. The tests are comprised of encryption processing, image compression, HTML5 parsing, physics calculations and other general purpose compute processing workloads.
The AMD Ryzen 9 3950X put up some strong numbers in Geekbench. In its default power mode, it was one of highest performing processors in both the single and multi-threaded tests. Only Intel's higher-clocked Coffee Lake-based processors offered better single-thread performance, and only the much more expensive, 18-core Core i9-9980XE put up a better multi-threaded score. Even in its low-power ECO mode, the AMD Ryzen 9 3950X is among the fastest processors here.

The AMD Ryzen 9 3950X's relatively high boost clock, support for up to 32-threads, and its huge total amount of cache, propel it into the lead in our PCMark 10 tests. It doesn't win across the board, though. Intel's Coffee Lake-based Core i9's outrun it in the "Essentials" test, where single-thread performance has more of an impact, but in the more heavily threaded "Productivity" and "DCC" tests, the AMD Ryzen 9 3950X come out on top.
