AMD's third-generation Ryzen platform has fully supported PCIe 4.0, from CPU processors to chipsets to GPU graphics cards, especially for scenarios that require higher-speed solid-state storage.
Intel has previously proposed many times that PCIe 4.0 is meaningless for consumer applications, especially gaming applications, but under competitive pressure, it is only a matter of time before Intel supports PCIe 4.0.
Now, the 10th generation desktop Core Comet Lake-S is about to be released, and the detailed specifications of the 11th generation desktop-level Rocket Lake-S have also been dug out, including native PCIe 4.0.
Statistics show, Rocket Lake-S processor will be based on new core architecture more powerful, but the specific unknown, rumors Willow Cove 14nm process, that is the end of the year and mobile 10nm Tiger Lake out of the same door, while introducing new Xe graphics architecture GPU core graphics card , support HDMI 2.0b standard, higher DDR4 frequency.
The most critical, of course, is to support 20 PCIe 4.0. Compared with PCIe 3.0 on mainstream platforms, there are 4 more, and exactly 16 are allocated to graphics cards and 4 to SSDs.
The AMD third-generation Ryzen platform supports up to 44 PCIe 4.0, of which 36 are externally available, including 24 of the third-generation Ryzen and 16 of the X570 chipset.
Rocket Lake-S processor will have a new 500 series chipset, but it still only supports PCIe 3.0 , and the communication channel with the 11th generation Core will continue to be DMI 3.0, but the bandwidth will be from x4 8GT / s (3.93GB / s) Doubled to x8 16GT / s.
The compatibility of the Rocket Lake-S platform is still unclear, but it is basically certain that the LGA1200 interface will be continued , but it is still unknown whether it can continue to support the 400 series motherboards that have not yet been released and also provide PCIe 4.0.
Back to the 500 series chipset, a major highlight will be native support for USB 3.2 Gen2x2, which is true USB 3.2, with a bandwidth of 20Gbps , but it is unclear how many interfaces will continue to support USB 3.2 Gen2 10Gbps (also known as USB 3.1). ), USB 3.2 Gen1 5Gbps (aka USB 3.0).
Thunderbolt 3's renamed vest version Thunderbolt 4 will be supported by an independent master and compatible with USB4 . After all, USB4 itself is completed based on the Thunderbolt 3 protocol.
In other respects, the 500 series chipset supports 2.5GbE wired network and integrated CNVi / Wirelss-AX wireless network, but will remove support for SGX (Software Protection Extension), and no longer support LPC, eMMC, SD 3.0, SDXC and other interfaces .
The Rocket Lake-S platform's release time is unknown, and it is expected to be early next year.
