Ryzen2-Feature

Everyone in the enthusiast community knows that manufacturer-provided benchmarks must be taken with a grain of salt. One could write a book on the various ways that companies tend to shade the truth to paint their ain products in a positive calorie-free. Some of these practices are defensible, at to the lowest degree to a sure degree — a visitor that chooses to put its best foot forrad by selecting tests in which it performs well may accept a perfectly defensible statement if the tests it chooses are well-known manufacture standards and stand for workloads the component is expected to run.

Other times, however, the changes companies make when comparing their hardware to other systems aren't defensible. And sometimes, they cross the line from "favors our ain products" into "blatantly misrepresents the performance of the contest."

Intel — or to be precise, a company Intel hired to create a whitepaper on Core i9 gaming performance — has crossed that line. According to Forbes, Intel contracted with Principled Technologies to distribute a whitepaper containing various claims about gaming functioning between Intel's upcoming Cadre i9-9900K and Cadre i7-8700K and the AMD Threadripper 2990WX, 2950X, and Ryzen 7 2700XSEEAMAZON_ET_135 See Amazon ET commerce. With AMD having surged into competitive positioning in the past 18 months and Intel taking heat from its 10nm delays, Chipzilla has every reason to push a narrative that puts information technology in the driving seat of gaming. But Intel is using this whitepaper to claim that it'southward up to l percent faster than AMD in gaming based on Ashes of the Singularity in particular, and that'due south where the problems start. The Intel results are somewhat higher than we'd expect, but the AMD CPUs — specially the Ryzen vii 2700X — are crippled.

In that location are several problems with the AMD benchmarks as run by Principled Technologies. PT was careful to document its own configuration steps on both systems, which is why we know what, precisely, the visitor did wrong.

Start, the Ryzen systems were tested without XMP enabled. XMP is the high-end memory timing standard that enthusiast kits use to hit maximum performance and Ryzen gaming operation is oft tied directly to its RAM clock and sub-timings. Using substandard timing could lower Ryzen's performance by 5-fifteen per centum.

Second, all of the benchmarks in question were run using a GTX 1080 Ti and a resolution of but 1080p. If you wanted to create a report tailor-made to Ryzen's weaknesses, that's the resolution you'd apply. Unfair? Not necessarily — it'due south the about mutual resolution subsequently all. Simply there's a reason we include 1440p and 4K results in our resolutions comparisons for gaming, and Intel/Principled didn't practise so.

3rd, Principled Technologies notes that it enabled "Game Mode" in AMD's Ryzen Master utility. The implication is that it did this on both systems. This can have serious side effects on how well an AMD system benchmarks. On Threadripper, engaging Game Style cuts the CPU core count in one-half and enables NUMA to allow the remaining CPU cores to schedule workloads on the cores closest to the retention controllers. On Ryzen 7, clicking Game Way just cuts the cadre count in one-half. That'south why AMD'southward user guide for Ryzen seven specifically states that Game Mode is reserved principally for Threadripper and that Ryzen customers shouldn't utilise it:

Ryzen-Master-Guide

If Principled had consulted AMD's documentation, it would've seen that it shouldn't exist using this test mode for Ryzen 7 in any instance. If information technology didn't consult AMD's documentation, it had no business organization using Ryzen Primary to adjust Ryzen 7 CPU settings. But the 50 percent performance gain that Intel claims for itself is exactly the kind of outcome nosotros'd await if the 2700X had been crippled by having its CPU neutered.

If you demand additional evidence of how crazy these scores are, consider our own 2700X review, which nosotros as well test with a GTX 1080 TiSEEAMAZON_ET_135 See Amazon ET commerce in the CPU focused benchmark (the same one PT used).

Their Core i7-8700K is actually a touch on slower than ours, but our Ryzen 7 2700XSEEAMAZON_ET_135 See Amazon ET commerce is a massive 1.36x faster. While our results use different detail settings, TechSpot really checked the exact results with AotS benchmarks of their own. In the graphs below, red bars indicate Principled Technologies results.

Epitome past TechSpot

Their Assassin Creed Origin tests are similarly broken:

Considering they're effectively benchmarking the Ryzen 7 2700X every bit a quad-core CPU with lousy memory timings, it'southward no particular surprise that the Ryzen 7 ends upward getting its ass kicked. This goes across just adjusting a few game settings in a way that favors your hardware but subtly disadvantages the competition. The Ryzen 7 2700X has been configured to run with half its cores disabled in a non-optimized memory configuration with sub-optimal timings while the Intel organisation was configured with an ideal memory subsystem and all of its cores and threads enabled.

Misrepresenting product performance past 3-5 per centum is a tilt. Misrepresenting information technology by 1.2x (AotS) and almost 1.25x (as in ACO) is a lie. And that means these results are lies. They may be lies of ignorance or error rather than the result of a deliberate malicious intervention, simply given Intel's history, enthusiasts are unlikely to extend much do good of the doubt. Even a casual readthrough of the document ought to accept defenseless these mistakes — if, in fact, they were mistakes. And even in the most charitable reading, Principled had no business organization using an application similar Ryzen Master if they weren't going to read the documentation AMD provides to tell you how to utilise the damn thing. Everyone tin can have a test run go poorly or mistype a number, but TechSpot establish prove of manipulation in every unmarried criterion they checked. Either the 8700K was strangely faster than it ought to have been, the 2700X was significantly slower, or both.

What makes the entire thing that much more perplexing is that we'd expect Intel to win this comparing anyway. There was no need to resort to crippling the 2700X to pull ahead. The company could've done that just past using 1080p and choosing tests where Ryzen doesn't compete equally well. The sharp-eyed would call foul, but people are used to taking vendor tests as preliminary indications at best. Instead, Principled Technologies has called into question its ain expertise and raised serious questions about what, exactly, Intel was attempting to achieve with this whitepaper.

When asked for comment past Forbes, Intel responded:

"We are deeply appreciative of the work of the reviewer customs and expect that over the coming weeks additional testing will continue to show that the 9th Gen Intel Core i9-9900K is the world's best gaming processor. Principled Technologies conducted this initial testing using systems running in spec, configured to show CPU performance and has published the configurations used. The data is consistent with what we have seen in our labs, and we look frontwards to seeing the results from additional 3rd party testing in the coming weeks."

Guys, I don't know what you think "in spec" looks similar, but running the 2700X with half its cores disabled doesn't fit the bill.
