The predominant enchancment is the CPU core itself, which is supposedly a 14 nm adaptation of Tiger Lake-U based mostly on Willow Cove core. This design is representing a backport of IP to an older manufacturing node, which ends up in greater die house because of bigger node used. When it involves the platform enhancements, it would assist the long-awaited PCIe 4.zero connection already current on competing platforms from AMD. It will allow a lot sooner SSD speeds as there are already PCIe 4.zero NVMe gadgets that run at 7 GB/s speeds. With RKL-S, there might be 20 PCIe 4.zero lanes current, the place 4 would go to the NVMe SSD and 16 would go to the PCIe slots from GPUs. Another attention-grabbing function of the RKL-S is the addition of Xe graphics discovered on the CPU die, meant as iGPU. Supposedly based mostly on Gen12 graphics, it would deliver assist for HDMI 2.0b and DisplayPort 1.4a connectors.
Some issues like Direct Media Interface (DMI) will double the bandwidth and now there might be eight hyperlinks current, in comparison with 4 of the earlier platforms. Announced at CES 2020, ThunderBolt Four may even be current together with USB 3.2 20G. Additionally, Intel Software Guard Extensions (SGX) have been eliminated to enhance the safety of the platform, because the SGX has proved to be fairly weak to many sorts of assaults and exploits. There are some up to date media encoding requirements as nicely, like 12-bit AV1/HEVC and E2E compression.
