The results explicitly say "AMD Athlon 200GE with Radeon Vega Graphics". Don't forget the AM1 platform had Athlons *with* an IGP, so it looks like this is continuing that low power/entry level desktop branding, rather than the de-IGPed Athlons on FM* sockets.
My best bet is that this is their way to avoid "tainting" the Ryzen brand with a very low performance desktop part - whilst they've dropped to 2C/4T on mobile and retained the Ryzen branding, the mobile parts are generally all lower specced than the desktop equivalents. Plus with the existing numbering they didn't really have many places to go with a 2C/4T desktop part (Ryzen 3 2100G?). If they've decided to reuse the Athlon brand for entry level desktop APUs I'm cool with that
As to the naming, 200 rather than 2000 might be a misread or a conscious decision to differentiate the numbering from the Ryzen line up (while retaining the '2nd gen' tie-in), the G suffix has so far denoted desktop APU (i.e. "graphics"), and AMD usually use E to mean Energy Efficient - so perhaps a 35W or 45W TDP?
EDIT: if you follow the Sandra link to the Lenovo machine listed there are results for an A6-9500 too, which matches the Lenovo ThinkCentre M715s - so OEM desktop processor looks about right. Whether we'll ever see it at retail or not who knows, but given the list prices for the Ryzen 3 2200G it should be pretty cheap. Also wonder if we'll see it host more Vega CUs than the laptop 2C chip ... the desktop versions so far have had more CUs than their closest laptop equivalents,. A 2C/4T/6CU desktop chip at ~ £60 would be a bit of a winner
imo....
