Intel claims Rocket Lake has faster storage performance than AMD Zen3
Intel’s Chief Performance Strategist Ryan Shrout and Storage Technical Analyst Allyn Malventano, are claiming that the upcoming flagship Core i9-11900K processor from the Rocket Lake-S series will offer up to 11% faster storage performance on PC Mark 11 Quick System Drive Benchmark compared to AMD Ryzen 9 5950X. This is actually the first official benchmark of the new processor. The series is expected to launch next month, but the company has not yet confirmed the exact launch date, but the fact that Intel is already showing benchmarks, may further confirm that the launch is imminent.
The test features 1TB Samsung 980 PRO, which is PCI Gen4 compatible drive. According to Ryan Shrout’s tweets, the disc was attached to the PCIe riser, to ensure it is using CPU lanes as opposed to chipset lanes. In such a scenario, the i9-11900K is 11% faster than AMD Ryzen 5950X, which is the flagship “Vermeer” CPU based on Zen3 architecture.
AMD X570 motherboards were the first PCIe Gen4 capable platform from AMD. The company was expected to provide partial support on older motherboards, but the plans were eventually scrapped. On the other hand, Intel has launched its Z490 motherboard series last year with PCIe Gen4 hardware readiness for the 11th Gen Core series which would not launch until this year. Intel has not yet confirmed which Z490 motherboard will support the newer standard, but even if they do support it, it will be limited. Intel Rocket Lake-S CPUs are the first series to have dedicated CPU lanes for the PCIe Gen4 storage and this feature will be exclusive to Z590 chipsets.
