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

The office programs we use for benchmarking aren't specific programs per-se, but industry standard tests that hold weight with professionals. The goal of these tests is to use an array of software and techniques that a typical office user might encounter, such as video conferencing, document editing, architectural modeling, and so on and so forth.
All of our benchmark results can also be found in our benchmark engine, Bench.
Chromium Compile (v56)
Our new compilation test uses Windows 10 Pro, VS Community 2015.3 with the Win10 SDK to compile a nightly build of Chromium. We've fixed the test for a build in late March 2017, and we run a fresh full compile in our test. Compilation is the typical example given of a variable threaded workload - some of the compile and linking is linear, whereas other parts are multithreaded.
One of the interesting data points in our test is the Compile, and it is surprising to see the 1920X only just beat the Ryzen 7 chips. Because this test requires a lot of cross-core communication, the fewer cores per CCX there are, the worse the result. This is why the 1950X in SMT-off mode beats the 3 cores-per-CCX 1920X, along with lower latency memory support. We know that this test is not too keen on victim caches either, but it does seem that the 2MB per core ratio does well for the 1950X, and could explain the performance difference moving from 8 to 12 to 16 cores under the Zen microarchitecture.
PCMark8: link
Despite originally coming out in 2008/2009, Futuremark has maintained PCMark8 to remain relevant in 2017. On the scale of complicated tasks, PCMark focuses more on the low-to-mid range of professional workloads, making it a good indicator for what people consider 'office' work. We run the benchmark from the commandline in 'conventional' mode, meaning C++ over OpenCL, to remove the graphics card from the equation and focus purely on the CPU. PCMark8 offers Home, Work and Creative workloads, with some software tests shared and others unique to each benchmark set.
Strangely, PCMark 8's Creative test seems to be failing across the board. We're trying to narrow down the issue.
SYSmark 2014 SE: link
SYSmark is developed by Bapco, a consortium of industry CPU companies. The goal of SYSmark is to take stripped down versions of popular software, such as Photoshop and Onenote, and measure how long it takes to process certain tasks within that software. The end result is a score for each of the three segments (Office, Media, Data) as well as an overall score. Here a reference system (Core i3-6100, 4GB DDR3, 256GB SSD, Integrated HD 530 graphics) is used to provide a baseline score of 1000 in each test.
A note on context for these numbers. AMD left Bapco in the last two years, due to differences of opinion on how the benchmarking suites were chosen and AMD believed the tests are angled towards Intel processors and had optimizations to show bigger differences than what AMD felt was present. The following benchmarks are provided as data, but the conflict of opinion between the two companies on the validity of the benchmark is provided as context for the following numbers.

And consoles are on the verge of moving to many-cores main CPUs. The inevitable dev change will spill over into PC gaming.RoboJ1M - Friday, August 11, 2017 - link
On the verge?All major consoles have had a greater core count than consumer CPUs, not to mention complex memory architectures, since, what, 2005?
One suspects the PC market has been benefiting from this for quite some time.

Specifically, the 360 had 3 general purpose CPU coresAnd the PS3 had one general purpose CPU core and 7 short pipeline coprocessors that could only read and write to their caches. They had to be fed by the CPU core.
The 360 had unified program and graphics ram (still not common on PC!)
As well as it's large high speed cache.
The PS3 had septate program and video ram.
The Xbox one and PS4 were super boring pcs in boxes. But they did have 8 core CPUs. The x1x is interesting. It's got unified ram that runs at ludicrous speed. Sadly it will only be used for running games in 1800p to 2160p at 30 to 60 FPS :(

Why do people constantly assume this is purely time/market economics?Not everything can *be* parallelized. Do people really not get that? It isn't just developers targeting a market. There are tasks that *can't be parallelized* because of the practical reality of dependencies. Executing ahead and out of order can only go so far before you have an inverse effect. Everyone could have 40 core CPUs... It doesn't mean that *gaming workloads* will be able to scale out that well.
The work that lends itself best to parallelization is the rendering pipeline and that's already entirely on the GPU (which is already massively parallel)

I think what AMD did here though is fantastic. In my mind, creating a switch to change modes vastly adds to the value of the chip. I can now maximize performance based upon workload and software profile and that brings me closer to having the best of both worlds from one CPU.Notmyusualid - Sunday, August 13, 2017 - link
@ rtho782I agree it is a mess, and also, it is not AMDs fault.
I've have a 14c/28t Broadwell chip for over a year now, and I cannot launch Tomb Raider with HT on, nor GTA5. But most s/w is indifferent to the amount of cores presented to them, it would seem to me.

Great review but the word "traditional" is used heavily. Given the short lifespan of computer parts and the nature of consumer electronics, I'd suggest that there isn't enough time or emotional attachment to establish a tradition of any sort. Motherboards sockets and market segments, for instance, might be better described in other ways unless it's becoming traditional in the review business to call older product designs traditional. :)mkozakewich - Monday, August 14, 2017 - link
Oh man, but we'll still gnash our teeth at our broken tech traditions!lefty2 - Thursday, August 10, 2017 - link
It's pretty useless measuring power alone. You need to measure efficiency (performance /watt).So yeah, a 16 core CPU draws more power than a 10 core, but it also probably doing a lot more work.

Er why don't you just do it yourself, they've already given you the numbers.
