@erik, The number is given in “Gigabytes per second”, usually you refer to an ‘x16’ slot as one with 16 lanes receiving and 16 lanes transmitting, so this means 128 GBps in and 128 GBps out simultaneously

It’s fantastic that there’s still someone sticking to a sensible and understandable spec naming scheme.

I’m looking at you – USB, HDMI and WiFi.

@creker, there’s quite a bit of stuff on that link not behind a paywall, so technically “more info” is correct.

“If you want to learn more, check out the specification page here”
Funny. I want to learn more but I can’t. PCIe specification is available only for PCI-SIG members or you can buy it for 4500$ which is insane. Many other major specifications like CXL and nvme are available to anyone for free, like it should be.

To satisfy the Gen6 bus speeds you will need DDR5-5000 in 8 channels, so this will be expensive and for Xeon servers for a while
