Launch date 7/7/2019, Vega 11 graphics, 4 cores (8 threads).
Yeah. There have been increasingly plausible rumours that the 4xxxG range is coming soon, but right now AMD seem to be focused on the much larger laptop market (which also benefits a lot more from the really good power efficiency of their current chips).
I bought a 2400G last year, which I've been pretty happy with - but I'm very much looking forward to dropping a 4xxxG into the same socket later this year!
Zen 2 based APUs are coming out really soon. Up to 8c/16t, 65W.
