Finally something decent
I've given AMD a repeated knocking as being useless in practically all markets except the low end consumer integrated CPU and graphics market.
The G series processors are another area where they score, see the APU2C4 at PC Engines : http://www.pcengines.ch/apu2b2.htm. The prior APU1d4 was a bit shit, featuring a slow AMD processor (G T40e), that although faster than their previous Alix boards (AMD Geode), actually worked out slower due to a lack of integrated cryptography accelerator.
The APU2c4 contains a GX-412TC, 64 bit CPU with up to 6W and built in AES-NI. In short, it's actually usable for embedded apps, and appears to be cheaper than finding a small footprint Atom based Intel system (which are not fanless). I'm impatiently waiting for it to be in stock..
