Initial estimates were 40% over BD/excavator. I’ve never seen a Jaguar comparison, but this is the most conservative I could make it (on top of the conservative clock gains). https://www.anandtech.com/show/1114...or-under-330-preorder-today-on-sale-march-2nd I also realistically expect a 3-4x factor, workload dependent. Edit. Here’s a good source: https://www.anandtech.com/show/1059...art-2-extracting-instructionlevel-parallelism Let’s say that’s 50% IPC over Jaguar. Add another 5% for Zen+, then another 15% for Zen 2. 1.8x sound fair? Edit: well well well...

It also includes dynamic per-module clocking based on bandwidth needs.
