PCI Express 4.0 to double bandwidth to 64GB/s

Tom's Hardware writes the PCI Express 4.0 specification is getting a step closer to introduction. Hardware companies are drafting the new standard, which will enable a base speed of 16Gbps per data link, resulting in a bandwidth of 64GB/s for a 16 lane port. Besides doubling the bandwidth for high-end applications, PCIe 4.0 also promises to cut costs.
It's also expected to cut costs, as odd as that sounds. In the same way that shifting to a smaller manufacturing process for CPUs and GPUs can help cut costs by reducing component waste and helping systems run more efficiently, moving to a quicker expansion slot speed means manufacturers can use fewer data links or assign more tasks to each one, cutting down the total cost dramatically.
