The new chip will reportedly draw more power than Intel’s current chips — which is hardly surprising, since it will have an extra processor core. The 1.83GHz Intel Atom N470 chip, for instance, has a total power draw of 6.5W, while the new dual core chip will have a TDP of 8.5W. That covers both the processor and graphics core, since they’re built into the same chip. Earlier Intel Atom processors had much lower power consumption figures — but that was because the graphics and memory controllers were part of the larger chipset.
Fudzilla doesn’t have any info on the launch date for these new chips — and since the web site isn’t citing its sources, I’d take the info with a grain of salt for now. But it all seems quite plausible.
