The benchmarks yielded some interesting results, which you can check out over here. The first set of tests investigated the performance of the Samsung 960 EVO 1TB PCIe SSD, while the second round of testing took a look at SATA storage performance with the Samsung 750 EVO 500GB SSD. The difference in performance is smaller than in the past but AMD is still at a disadvantage, especially in terms of random read performance and performance with small sequential files.
We are pleased with the PCIe storage performance that Ryzen delivers. It is within striking distance of Intel and we believe that for the most part user experience between the two platforms is comparable. However, SATA performance between the two platforms is another matter. Ryzen is at a distinct disadvantage compared with Intel if you are running a SATA SSD.The site explains one of the reasons why AMD is at a disadvantage is because the company has no SATA driver, whereas Intel has its RST driver as well as a superior chipset.
