Leading up to the AMD Next Horizon Gaming event, Intel is very convey to its competitor the desire to compete in gaming performance, clearly doubting that the new desktop processors of the Ryzen 3000 family have a chance to surpass the "world's best gaming CPU" Core i9-9900K. However, AMD decided to answer this challenge and, as part of its presentation, showed the results of testing the flagship third-generation Ryzen models in some, mainly networked, games. The slides presented by AMD CEO Lisa Su leave no doubt: AMD believes that Intel's confidence is groundless, and the crown may well go to its chips, as they are able, if not to bypass, then at least not to concede solutions of a competitor of a similar class in real problems.
So, according to AMD, the $12 9-core Ryzen 3900 499X delivers about the same 1080p gaming performance as the $500 Intel Core i9-9900K.
The gaming performance of the $7 octa-core Ryzen 3800 399X is similar to that of the slightly cheaper Core i7-9700K.
And the six-core, $249 Ryzen 5 3600X in games is about the same frame rate as the Core i5-9600K, which is officially priced at $263.
It is worth mentioning that AMD points to a number of reasons why its new processors are noticeably superior to their predecessors in terms of gaming performance.
In addition to the 15% increase in IPC (instructions executed per clock), factors such as better optimization of the Windows Task Manager, doubling the size of the L3 cache, and reducing the effective latency of the memory subsystem have a significant impact.
According to information AMD made public during the technical talks at Next Horizon Gaming, the Windows 10 May 2019 Update Task Manager correctly detects processor CCXs (Core Complex) and loads cores within a single CCX first, avoiding increased data transfer latencies. In addition, the new version of the operating system significantly accelerates the switching of clock frequencies when the turbo mode is activated and the processor wakes up from sleep.
Also included in the Ryzen 3000 is a significantly improved memory controller. The memory mode recommended by the manufacturer for new processors is DDR4-3600 CL16, but they can also work with DDR4-3733 SDRAM with synchronous clocking of the memory controller and the Infinity Fabric bus, and even with DDR4-4400 SDRAM if you select the memory and Infinity clock ratio scheme Fabric using a 2:1 divider.
At the same time, the gaming test results demonstrated by AMD cannot be considered a "pure" experiment. First, for some reason, the company decided not to disclose the configuration of the test systems in which the comparison was made. Secondly, the selection of games for testing also raises some questions, not to mention the fact that even according to the tests of AMD itself, one cannot speak of any unconditional victory.
However, even if AMD ultimately fails to win in terms of gaming performance, the Ryzen 3000 has other powerful trump cards. First of all, this is a significant superiority in speed in the tasks of creating and processing digital content. Specifically, the company is talking about a 29 percent advantage for the Ryzen 9 3900X over the Core i9-9900K in such applications.
Further, the average advantage of the Ryzen 7 3800X over the Core i7-9700K in resource-intensive tasks is 24%.
And the average superiority of the Ryzen 5 3600X over the Core i5-9600K reaches 30%.
The reasons why Ryzen 3000 processors are faster in creative applications are well understood. AMD's strategy is that its products at the same cost as competitor solutions have either more cores or more threads due to the support of SMT technology.
Therefore, there is nothing surprising in the fact that AMD processors perform better, including when streaming games. For example, AMD has shown that the 12-core Ryzen 9 3900X "pulls" the software H.264 encoding of the video stream with the Slow quality preset, while the competing Core i9-9900K passes under such a load.
And another trump card of the Ryzen 3000 family is the best efficiency. Comparing the ratio of consumption and performance of processors in Cinebench R20, AMD comes to the conclusion that its new chips are 20-50% more energy efficient than competitor solutions of a similar (in terms of cost) class.
Thanks to this, third-generation Ryzen-based systems not only save power, but also run cooler, allowing the user to save money by purchasing a simpler cooling system.
