Intel: Rocket Lake-S offers 11% higher PCIe 4.0 performance than AMD Ryzen 9 5950X

Intel performance strategist Ryan Shrout provides a sneak peek at the disk performance of the upcoming Rocket Lake-S processor. In a message shared on Twitter, Shrout reveals the Intel Core i9-11900K scores up to 11 percent faster on PCMark 10 Quick System Drive Benchmark versus the AMD Ryzen 9 5950X.

No actual benchmark data is provided, instead, Shrout offers a relative performance comparison. Both systems used the Samsung 980 Pro PCIe Gen4 SSD. Testing was performed using a x16 slot with a riser card, to ensure the Samsung 980 Pro was CPU attached on both platforms. Rocket Lake-S is the first Intel platform with dedicated PCIe 4.0 CPU lanes -- this feature will require the Z590 chipset.

Rocket Lake-S is expected to hit the market next month. Based on current roadmaps, this will be the last 14nm mainstream desktop processor. The chip is also the last to use the LGA1200 socket, the future Alder Lake-S will switch to LGA1700 due to the inclusion of DDR5 and PCI Express 5.0 support. Rocket Lake-S packs a new "Cypress Cove" core design with higher IPC as well as Xe-based integrated graphics.

At #CES21 we looked at Rocket Lake-S gaming. Here’s a sneak peek of Core i9-11900K PCIe Gen 4 storage performance - up to 11% faster on PCMark 10 Quick System Drive Benchmark vs the 5950X. Thanks @Malventano for the data. Backup: https://t.co/LcI5n5Cok2 pic.twitter.com/NhblHRQJSC
