They already supported this line rate though, for years? What am i missing? (IE It's still only pcie gen3, and this announcement doesn't change that)

- smallmancontrov 3y agoSpartan 6 had transceivers. Spartan 7 dropped them. Boo. Spartan UltraScale+ brings them back. Hooray! (Though to morphie's point we should probably hold the champagne until we see pricing.) Also, it looks like PCIe Gen 4. The bitrate is enough and the page says Gen4x8. Is there something I'm missing?
- morphle 3y agoYes, we are missing vital information. Similar issues as Artix Ultrascale+ where the small print says " PCIe Gen4 is available in AU10P and AU15P in the FFVB676 package. AU10P and AU15P in other packages support Gen3x8.". Same die for all these FPGAs but not same speeds at given prices. Most of the die will be disabled, 'binned'. So Spartan 7 Ultrascale+ can theoretically support 8 lanes of PCIe Gen 4.0, but if they actually do at the price you pay is unclear and also if the PCIe 4 IP is free or very expensive and only available in the expensive toolchain under NDA?
