According to leaked slide by Baidu, the upcoming Intel 13th Gen Core “Raptor Lake-S” desktop CPUs now officially support DDR5-5600 memory and DDR4-3200 memory.
According to leaked slides, the new platform gets support for more PCIe Gen 4.0 lanes through the chipset, however there is no mention of additional Gen 5.0 lanes. The platform would still be limited to 16 available exclusively through from the CPU. This means that Raptor Lake-S PCIe Gen5 lanes will be split between storage and GPU at the same time.
As rumored before, Intel Raptor Lake-S processors will be released in October 2022. Stay tuned for more info.
