The AMD Ryzen Threadripper 1950X and 1920X Review: CPUs on Steroids

Our legacy tests represent benchmarks that were once at the height of their time. Some of these are industry standard synthetics, and we have data going back over 10 years. All of the data here has been rerun on Windows 10, and we plan to go back several generations of components to see how performance has evolved.
All of our benchmark results can also be found in our benchmark engine, Bench.
3D Particle Movement v1
3DPM is a self-penned benchmark, taking basic 3D movement algorithms used in Brownian Motion simulations and testing them for speed. High floating point performance, MHz and IPC wins in the single thread version, whereas the multithread version has to handle the threads and loves more cores. This is the original version, written in the style of a typical non-computer science student coding up an algorithm for their theoretical problem, and comes without any non-obvious optimizations not already performed by the compiler, such as false sharing.
CineBench 11.5 and 10
Cinebench is a widely known benchmarking tool for measuring performance relative to MAXON's animation software Cinema 4D. Cinebench has been optimized over a decade and focuses on purely CPU horsepower, meaning if there is a discrepancy in pure throughput characteristics, Cinebench is likely to show that discrepancy. Arguably other software doesn't make use of all the tools available, so the real world relevance might purely be academic, but given our large database of data for Cinebench it seems difficult to ignore a small five minute test. We run the modern version 15 in this test, as well as the older 11.5 and 10 due to our back data.
x264 HD 3.0
Similarly, the x264 HD 3.0 package we use here is also kept for historic regressional data. The latest version is 5.0.1, and encodes a 1080p video clip into a high-quality x264 file. Version 3.0 only performs the same test on a 720p file, and in most circumstances the software performance hits its limit on high-end processors, but still works well for mainstream and low-end. Also, this version only takes a few minutes, whereas the latest can take over 90 minutes to run.
The 1950X: the first CPU to score higher on the 2nd pass of this test than it does on the first pass.

"well above the Ryzen CPUs, and batching the 10C/8C parts from Broadwell-E and Haswell-E respectively"??? From the Power Consumption page.

Yep if you use AVX-512 it will down clock to 1.8Ghz and draw 400w just for the CPU alone and 600w from the wall. See der8auer's video title "The X299 VRM Disaster (en)", all x299 motherboards VRMs can be ran into thermal shutdown under avx 512 loads, with just a small overclock, not to mention avx512 crazy power consumption. That is why AMD didn't put avx 512 in Zen, it is power consumption monster.TidalWaveOne - Thursday, August 10, 2017 - link
Glad I went with the 7820X for software development (compiling).raddude9 - Thursday, August 10, 2017 - link
In ars' review they have TR-1950X ahead of the i9-7900X for compilation:https://arstechnica.co.uk/gadgets/2017/08/amd-thre...
In short it's very difficult to test compilation, every project you build has different properties.

Yeah, the discrepency is huge - converted to anandtech's compile's per day the arstechnica benchmark maxes out at a little less than 20, which is a far cry from the we see here.Clearly, the details of the compiler, settings and codebase (and perhaps other things!) matter hugely.
That's unfortunate, because compilation is annoyingly slow, and it would be a boon to know what to buy to ameliorate that.

This is very compiler dependent. My compiler is blazingly fast on my wimpy hardware becuase it's blazingly clever. Most compilers seem to crawl no matter what they run on.bongey - Thursday, August 10, 2017 - link
Looks like anandtech's benchmark for compiling is bunk, it's just way off from all the other benchmarks out there. Not only that, no other test shows a 20% improvement over the 6950x which is also a 10 core/20 thread cpu. Something tells me the 7900x is completely wrong or has something faster like a different pcie ssd.Chad - Thursday, August 10, 2017 - link
All I know is, for those of us running Plex, SABnzbd, Sonarr, Radarr servers simultaneously (and others), while encoding and gaming all simultaneously, our day has arrived!:)

We checked with Ars as to their method.We use a fixed late March build around v56 under MSVC
Ars use a fixed newer build around v62 via clang-cl using VC++ linking
Same software, different compilers, different methods. Our results are faster than Ars, although Ars' results seem to scale better.

Of every review out there, only your "superior testing methodology" presents a picture where TR is slower than SX.
