Intel targets PCIe 5.0 and DDR5 by 2021
While we have yet to find a scenario where we can properly saturate PCIe 4.0 in the consumer space, server applications would definitely welcome the extra bandwidth. Intel is planning on capitalizing on that as they are reportedly working on bringing both PCIe 5.0 and DDR5 to the server space in 2021.
The upcoming Sapphire Rapids series will be the generation which Intel launches support PCIe 5.0 and also an eight-channel DDR5 controller. This will translate to massive amounts of bandwidth to the memory and storage, accelerating any data-intensive workloads. And it will require the massive LGA4677 socket.
They will also be based on a new core architecture called Willow Cove, which will be the next step forward for Intel after the Sunny Cove architecture we see with the Ice Lake processors.
Sapphire Rapids is expected to come in 2021, which leaves little room for the Ice Lake-based Xeon parts in 2020.
Pokdepinion: I wonder how much of a premium DDR5 will have over current DDR4 memory.
