Is anybody looking at the recently available AM1 platform?
Isn't Bay Trail even better?
Not really though it depends what you're looking for. Bay Trail has lower TDP and indeed their peak power consumption is lower (should definitely be easier to cool passively). At idle it seems to be more of a wash (the difference depending on the mobo used seems to be quite a bit larger in any case). In terms of cpu performance, Bay Trail is slower per clock but makes this about up with faster clocked parts (the fastest AM1 chip clocks at 2.05Ghz but the faster Bay Trail parts turbo up to ~2.5Ghz), so cpu performance is very similar in the end (of course, this depends on the exact chip). Unless you run some very specific code (bay trail doesn't support avx, and the "normal" desktop and mobile pentium/celeron parts have afaik all AES disabled) where AM1 chips have the advantage.
Graphics OTOH is a definite win for AM1 chips - I'd say roughly twice as fast comparing the fastest chips, even the slowest am1 chip (sempron 2650) might be able to beat the fastest bay trail-d part.
I'm not entirely sure how prices will turn out this is all a bit new so not many comparison points (obviously, the price of the board matters).
