I've been looking, still can't seem to locate them. I'm pretty sure they were on ti.com, though, if you want to poke around.

Basically, yes, I believe it's just an overclocked OMAP3430 (Speed-sorted batches of OMAP3430s that can handle 800MHz without cooking themselves mostly likely). Problem is, the core voltage was jacked way up (I want to say 1.2v vs 1.6v).

With ARM, a faster core means a shorter time to idle, means lower overall power consumption (Race to Idle), but I think the increased power requirements would offset this. Would there be a difference, though, at 1% CPU with both devices in the same op-mode? I don't know, but in practical active usage, I believe the OMAP3430 will come out on top.

By "HD" do we mean video? In the case of the RX-51, decoding is going to be handled DSP-side (430MHz C64x+). I dunno about the Archos, but the Beagle has been doing 720p with NEON-only optimizations (ARM-side) since forever.

Bigger than the SoC power consumption-wise, though, are the screen (5" is a lot more backlight to drive) and hard drive.

For Nokia, I think it's likely a combination of availability (the OMAP3440 is a much more recent beast than the OMAP3430), cost, and battery life.
