Of most interest is the graphics numbering for the lowest SKU A6-6300, 8370D.
That's interesting because what we believe to be the highest Kabini SKU, the A6-5200 (I'm going to assume this will be renamed as the A6-6200), has graphics numbered as 8400 -

Let's assume the 6300 has the same 128 SP's as the 5300, and if that leak is correct they are at 760 MHz. This should give us a reasonable indication of Kabini's stats, however the single channel memory troubles me a bit as I'd have thought that would hurt performance a lot.
Best guess says 25W, 4 cpu cores at unknown speeds and 128 SP's at 800 MHz though. AMD would not give it the 8400 name unless it was faster in graphics than the Richland 6300.
For those of you who aren't really keeping up with these bottom end APU's, I reckon the performance should be fairly close to the A6-3500

It looks like a huge perf/watt increase anyway, as these A6's are rated 65W (from what I've seen of them, 50W appears to be a bit closer to the average). Still, looking at a doubling of Perf/Watt in all likelyhood.
The A6-6400K will probably be about the same (in gaming) as the Llano 3870K btw.
