Windows 10 is finally optimized for AMD Ryzen processors with the May 2019 update
Apparently, Windows 10 could not get the most out of Ryzen processors at the moment for lack of optimization. Fortunately, since the May 2019 update, Microsoft has made two improvements: one is Topology Awarenesswho benefits from Full CCX Ryzen processors (each of the main blocks) before moving on to the next, which reduces the latency and the time required for the execution of tasks, because the load is better distributed. Until now, the load passed from one CCX to another without stopping, which increased latency and reduced performance.
Secondly, it has also improved the time needed to increase the frequency of the processor when performing a task. Where before they were 30 ms, now they are only 1 or 2 ms.
These improvements affect all processors Zen, Zen + and the future Zen 2. Until now, Windows 10 was optimized for Intel processors. This is one of the reasons why operating system performance or games were worse initially with AMD processors. However, over the past two years, its optimization has been improved and changes such as Windows 10 1903 have allowed AMD processors, with a high probability, to perform better than Intel.
It will be necessary to redo all the performance tests for the moment, because those which were until now useless. Intel lost about 13% performance for the vulnerabilities that have appeared in the last 18 months (especially Meltdown), and AMD, in addition to being barely affected, now produces a 30% higher return.
AMD did the test with a Ryzen 7 3800X to check what is the improvement, and in Rocket League at 1080p on bass: 15% more performance, while PCMark 10 has improved its performance by 6%.
Several users have defined the 3DMark benchmark before and after the update, and the improvement is 7% for one of them (1809 and 1903) and 10% for the other (1809 and 1903). Some users have improvements of up to 13% in Fire Strike and Time Spy.
AMD has managed to reach Intel in gaming performance
This would make AMD equal to the equivalent Intel processors in the range they cover, to which must be added the improvement of the Zen CPI 2. In addition, processors with Zen 2 architecture will be equipped with Spectrum V4 hardware protection, so performance will be even better compared to Zen and Zen + chips. L & # 39; architecture Zen 2 is immune to Meltdown, Foreshadow, Spectrum V3a, Lazy FPU, Spoiler. and the recently discovered vulnerability of MDS. However, Intel chips must always be corrected by software before Specter V4, Specter V3a, MDS and RIDL.
Thus, the optimization of Windows 10, the Specter V4 solution by the hardware and the Intel performance loss would explain the good figures AMD showed at E3, where the Ryzen 9 3900X offers the same performance as the Intel Core i9-9900K, but slightly better in most games, especially in CS: GO, one of the most CPU dependent.
