New performance benchmarks for Intel’s upcoming flagship processor Intel Core i9-11900K have been shared online which show the Intel flagship having a commanding lead over AMD’s flagship in PCIe Gen 4 performance. The performance benchmarks were shared by Ryan Shrout and they show a double-digit lead over AMD’s Ryzen 5000 CPUs in PCIe Gen 4.0 storage performance.

The Intel i9-11900K was compared with the AMD Ryzen 9 5950X which happens to be AMD’s flagship for its Ryzen 5000 CPU family. Both CPU’s PCIe Gen 4 performance was tested using a Samsung 980 Pro (1 TB) NVMe SSD, 32 GB of DDR4-3200 MHz memory, the same software and OS versions, and an NVIDIA RTX 3090 graphics card. The Intel platform used a ROG Maximus XIII HERO motherboard while the AMD one utilized the ROG Crosshair VIII HERO.

The platform’s PCIe Gen 4 performance was tested using the PCMark 10 Quick System drive benchmark with both systems having drivers at 50% prefill. In this benchmark, the Intel Rocket Lake Core i9-11900K CPU performed 11% better than the AMD Ryzen 9 5950X.

Some independent benchmarks of Rocket Lake-S flagship’s PCIe Gen 4 performance also leaked out earlier which showed some great PCIe Gen 4 storage performance numbers although with Z490 motherboards.

The Core i9-11900K is the flagship processor of the upcoming Intel 11th Gen Rocket Lake-S CPU series. It is based on the Cypress cove architecture which is the biggest CPU architectural upgrade in over 5 years. Ever since the 6th Generation Skylake CPUs, all Intel CPUs up till the 10th Generation Comet Lake CPUs used the same identical chip architecture based on the 14nm process node, with small refinements along the way.

The Intel Core i9-11900K will have 8 cores and 16 threads, 16 MB of L3 cache (2 MB per core), and 4 MB of L2 cache (512 KB per core). In terms of clocks, the CPU has a base frequency of 3.5 GHz but as for boost, the CPU will feature a maximum boost clock of 5.3 GHz (1-core) while the all-core boost frequency will be maintained at 4.8 GHz, powered by Intel Thermal Velocity Boost.
