At the PCI-SIG DevCon in June 2017 two announcements were made with regards to PCI Express specifications. The first is that the specification for PCIe 4.0 is now at version 0.9. The second and even more interesting announcement was of the new PCI Express 5.0 specification at the initial 0.3 version. With the PCI Express 5.0 announcement, the industry gets another doubling of speed from 16.0GT/s to 32GT/s per lane providing a bandwidth for a x16 (16 lanes) at about 128GB/s. The chart below provides a comparison for the different generations of PCIe rates and bandwidth.
Unless you are Rob Ford of course, if you live in North America, you probably spent your Sunday morning much like I did – going around to every clock in the house and setting it an hour forward. If not, or if you ARE Rob Ford, then I’m sorry I didn’t post this blog entry on Saturday…
Wow, I feel all official and everything now that my name is up in genuine electrons here! First I am compelled to correct Scott… I do have an appreciation for red wine. Without it there would be no red wine vinegar – which goes great on fries (chips for my EU friends)!
Virtualization technology essentially componentizes a computer system into the following:
The PCI-SIG Compliance workshop #84 is taking place December 4-7 in Milpitas, California. At the workshop, you can test your PCIe 3.0 device as part of the “official FYI testing” to see if your product passes compliance. However, “FYI” testing is “For Your Information” and not “official testing”, so even if your product passes compliance you won’t be able to list it on the PCIe 3.0 Integrator’s list because this is only FYI testing. Based on the ramp for Gen1 and Gen2, I’d expect “official testing” for Gen 3 to begin by mid next year.
