AMD has been the darling of the technology sector for quite a while now pushing the envelope for technological advancement ever forward but it looks like the company feels that its next-generation Ryzen 4000 mobility processors do not require PCIe 4.0 right now and will keep that particular platform at PCIe 3.0. This is interesting because Ryzen 4000 series processors, while being on the 7nm process, also do not contain Navi graphics as far as the GPU IP goes.

The interview was conducted by Japenese publication 4gamer.net and was attended by AMD's Scott Stankard (Senior Product Manager, Client Business Unit). AMD has been aggressively pushing PCIe 4.0 on its desktop side of things and this is one of the biggest selling points of its Zen 2 based processors right now. It was, therefore, eyebrow-raising, to see AMD not use PCIe 4.0 on its mobility side of things as well and give a response that seems very synonymous to the ones Intel gave for not pushing technology envelopes.
