AMD Ryzen Threadripper 1950X and 1920X – AMD's core competency put to the test

Yes, so for a good read- time: The Ryzen Threadripper 1950X has a whopping 16 cores, or 32 threads, 2 TB of addressable memory (which you couldn't even theoretically use in the absence of suitable 256 GB modules), ... Since it is difficult to get a pronounced server CPU for gaming optimally fit, AMD has provided in the Ryzen Master Tool a so-called game mode, which should help the Ryzen Threadripper to offer more performance in the current games. En... The AI test of Civilization VI is not a prime example of the Ryzen threadripper. Only the combination of overclocking and game mode (but only then) surpasses at least the Core i7-7820X. In the VRMark you can find the hierachia between the ... Frames per second Clock goes before core count, whereby the subtleties in detail again matter. Average and minimum FPS values are not everything. Nevertheless, all Ryzen Threadripper perform quite acceptable. The FPS history as a cure... Frames per second Clock again precedes core count, a typical symptom especially for older DX11 titles or Games whose engines don't really scale well with the number of possible threads. The FPS history as curves over the entire ru... Frames per second Why aren't we surprised? Clock is again (almost) everything, so that even the performance of the overclocked CPUs does not really surprise us. However, we refer to our detailed lists below, because also ... Frames per second Hitman (2106) is an Intel domain, which hasn't changed with Ryzen Threadripper. The differences in this benchmark are really serious. Despite or just because of DirectX12?  The fact is, however, that from approx. 140 FPS about... Frames per second The stronger CPUs are not so far apart in the end, which may also be due to the fact that the graphics card already starts to limit easily. However, despite the higher clock speed, the Ryzen Threadripper 1920X can not... Frames per second All CPUs are at a similarly high level, but there are differences. The FPS history as curves over the entire run looks like this when comparing all CPUs: Total Listing: Frame Times, Variance... Frames per second All CPUs are almost the same, which of course is also due to the graphics card. However, it also shows very nicely that you don't always have to have the thickest CPU to swim with older titles at the top. ... Frames per second Clock goes over core count and Intel dominates AMD. The differences are sometimes really serious. The FPS history as curves over the entire run looks like this when comparing all CPUs: Total listing: Frame Times, Va... Frames per second Clock goes over core count and Intel dominates AMD again - it's a similar image to Project Cars. The differences are mainly found in the Frame Times and their variances, but also the more detailed consideration of the... Frames per second We'll again forgo the game's slightly crashed DX12 mode and prefer to measure with the IX11 implementation. No matter which rendering path, AMD must beat the Intel CPUs in all variants. That doesn't mean it... Frames per second At first glance, the differences are rather marginal, because even with Ultra-HD, graphics-side limitations already occur. Nevertheless, it has above all the frame time and its variances in itself. Clock goes before Kerna...

CPU Performance: Workstation Of course, in the production area, not only the 3D graphics performance is important in the production area for the just-set applications, because many things are calculated by the CPU in parallel within these applications (Simu... For these test series, we use benchmarks from the rather versatile SPECwpc suite for workstations, which rely on very different mathematical calculations, which on the one hand can be perfectly parallelized and where it is at the same time a... The right cooling is important! One thing in advance: AMD dispenses with thermal paste between Die and IHS at the Ryzen Threadripper, but relies on the good old lot. This will open up completely new perspectives for us later on in the case of overclocking. En... Introduction We determine the performance values of the package in a special sensor loop, i.e. exactly the value for what is absorbed by the CPU in terms of power and then almost completely returned to the cooling system as heat. Surely it would be unfair and hateful if AMD were simply to be assumed, as with the Vega Frontier Edition, that everything that does not make it to the top positions in gaming is simply as productive hardware for the so-called prosumer (o...

For these test series, we use benchmarks from the rather versatile SPECwpc suite for workstations, which rely on very different mathematical calculations, which on the one hand can be excellently parallelized and where at the same time it is also very often things like memory bandwidth, cache, and latency.

Rodinia

The Pre-Euler3D CFD (Computational Fluid Dynamics Benchmark) test is really impressive, so it's no surprise that both thread rippers perform so well. What is interesting is that the extra clock of the overclocked versions is not so extremely important here.

Convolution

This is a benchmark for a sub-area of function analysis in which a new, third function is created as a product of two functions (convolution, folding). Here, the clock and the core count scale equally well.

CalculiX

This benchmark is based on a free finite element program for three-dimensional structural calculations. While the 8-core Ryzen7 still lags behind Intel's new Skylake-X, at least the 1950X Ryzen Threadripper can barely pass the Intel flagship Core i9-7900X.

Poisson's Equation

The Poisson equation is an elliptical, partial second-order differential equation that is used as part of boundary value problems in large parts of physics. The overclocked thread ripper can also not derive a (significant) advantage from the multiclock. The Intel Core i9 7900X remains the measure of all things in this test, especially since both thread rippers are only ahead of the other Core i9 due to their large number of cores.

Sequential Reweighted Message Passing (SRMP)

These are discrete energy minimization algorithms. The code isn't really in all AMD CPUs, but even here Threadripper can at least make up ground over the core count, which hasn't been enough with the Ryzen 7.

Kirchhoff Migration

The subsurface structure in the earth can be determined by seismic processing. One of the four basic steps is the Kirchhoff migration to model an image from the existing data using mathematical operations. The benchmark used, including the included calculations, is very accommodating to both Ryzen Threadripper.

Summary

AMD's thread rippers are both good or very well suited for almost all applications, as long as the respective compilation does not throw sticks between the legs, such as. in the SRMP test. However, we are sure that more and more application programs will also take into account the peculiarities of the AMD Ryzen family and such outliers will become rarer over time. Real demand for computing power and the presence of well-parallelizable tasks are the ideal field of application for AMD's Threadripper; you can leave it that way.
