All meat no potatoes?
From the article: "PCIe 3.0 ups the bus' based clock to 8GHz from 2.0's 5GHz. A change to the bus' line coding system, from 8/10-bit to 128/130-bit further increases the amount of data that can be pumped down the PCI pipe every second. So while PCIe 2.0 can do 4bn transfers a second, PCIe 3.0 can do 8bn"
What I was really looking for was bandwidth, and according to these guys* for an x16 is 32 GB/s vs. the prior 16 GB/s... which IMO makes the whole PCIe-based SSD stuff even that much more attractive (although lower prices would be nice:)
