I know very little about electronics design, so I always find it amazing that they keep managing to double PCIe throughput over and over. Its also probably the longest lived expansion bus at the moment.

It's less surprising if you realize that PCIe is behind Ethernet (per lane).

Which Ethernet standard? Light online searching leads me to believe it tops out at 800Gb/s. (and not in a format I would normally call Ethernet)

		Look at throughput on a single lane from the MAC to the PHY. 802.3dj is maybe finishing up soon and has 200gbps lanes. Which is more or less about what pci-e 8.x is supposed to be. The table in the article sums both directions of a lane, which leads to confusion. People want faster ethernet in fewer lanes, so no doubt a 400gbps per lane standard will be starting up soon for pci-e to leverage as pci-e 9. > not in a format I would normally call Ethernet Why, because it doesn't use ether, or vampire taps? Ethernet works over many media, and that's been pretty consistent throughout its life. It started from or at least was inspired by AlohaNet a wireless system, then you had thick and thin coax, then twisted pair and fiber, now twinax and board level interfaces are common, too.

		Ethernet has 100 Gbps per lane today and soon will have 200 Gbps while PCIe has 32 GBps today and soon will have 64 Gbps per lane.

I’m sure you can get some VMEbus boards.
