For months, there have been rumors about Intel's Alder Lake-S being the first chip to support both DDR5 and PCI Express 5.0 technology. Now it appears there may be a caveat.

PCI Express 5.0 support limited to the CPUs?

According to listings on the PCI-SIG website, the upcoming 600-series chipsets from Intel only support PCI Express 4.0 in x4 configuration and not the new PCI Express 5.0 specification. If this information is accurate, it means 600-series computers will only have PCI Express 5.0 via the CPU lanes. This could be a measure to keep motherboard costs down.

Intel's Alder Lake-S is expected to hit the market towards the end of this year. It will be a 10nm processor with a hybrid core architecture, featuring up to eight high-performance cores and up to eight energy-efficient cores. Source:
