I started to post this earlier. Lisa Su said that Ryzen hit 52% IPC improvement over excavator. The goal was 40%, which would have brought AMD to nearly on par in single threaded workloads. I haven't done any calculations or chased any down but I believe 52% put them a little above Intel in IPC. AMD has usually been strong in multicore and even with the change to a hyperthread type system (as opposed to the CMT modules approach) they should remain strong. They've really improved the front end and word is that at least one board (MSI?) should support 3200mhz DDR4 in dual channel. If so, that is going to help the APU side as well (as will rumored HBM onboard if that proves true). The sweet spot for me is the 1400x. IIRC 2/28 is the end of the embargo on reviews.
