Full details of the Intel Rocket Lake-S processors have been released. These processors, as the most interesting element, will be the integration of the PCIe 4.0 interface. Thus we will have the first processors based on this interface first implemented by AMD. These Rocket Lake-S processors will be the ones that must compete with AMD's Zen3 processors, something that looks quite complicated.
Not only will it integrate PCIe 4.0, other technologies and solutions are integrated in order to be at the forefront. These new processors will integrate Intel Xe graphics, being the first desktop processors to integrate it. Additionally it will integrate Thunderbolt 4 and the USB 3.2 interface.

So are Intel Rocket Lake-S processors
We have seen the first image that describes the communication with the chipset and the characteristics of these processors. The chipset will be the Intel 500 Series and a new motherboard change can practically be guaranteed. Note that Rocket Lake-S will be an update to the Comet Lake-S processors, with notable improvements.
The first big change is at the new core architecture level, about which little else is known. It could be a 14nm adaptation of the Tiger Lake processors, but there is no data to confirm this.
For the first time, Intel processors will support the PCIe 4.0 interface, a technology currently only present in AMD processors. 16 lines will be enabled for the GPU and 4 lines for NVMe SSDs.
DMI 3.0 x8 support is added which means doubling the transfer speed with respect to x4. Intel has not yet confirmed this information.
Rocket Lake-S processors are the first to integrate Intel Xe graphics, which will be a performance leap. If confirmed, they would get HDMI 2.0b and DisplayPort 1.4a support, thus lacking HDMI 2.1 support.
Increase peripheral transfer speed by adding Thunderbolt 4 and USB 3.2 support. Transfer rates will be improved and above all, with this new Thunderbolt interface, the ability to expand connectivity.
Rocket Lake-S will no longer have Intel Software Guard Extensions (SGX)
These processors are expected to hit the market later this year. We do not have more data at this time, but we will be attentive in case more information is released.
