Nah, the OMAP3440 is 800MHz, while the OMAP3430 is 600MHz (I just redid the OMAP wiki page, which has some details). Basically, this thing is going to be a power hog like no other. The consumption jump between the OMAP3430 and the OMAP3440 is . . . non-trivial (I had some numbers at some point, but I can't seem to dredge the up).
