A pity it's got to be that low -- Atom Z2460 has a TDP of 4w... it's an SoC Atom from what I understand -- meaning no chipset, just add RAM, VReg, and a few interface bits.
yep. intel's been told... but they keep taking the advantage of the geometry shrinks to increase speed, *not* reduce power.
so they're deliberately pissing in their own back yard, basically.
But there's no way to keep the required external components less than a watt, I'm sure.
32 bit 800mhz DDR3 (1.5v) RAM uses only around.... 300mA (0.3A), so it's doable.
Worth noting, even VIA can't keep up with that. Closest is an Eden ULV 1.0GHz Esther core... it gets 3.5w TDP but that's before the chipset and everything else...
yyep... and the eden is only in 45nm and isn't a very good design... *and* x86 has a performance/watt penalty inherent in its design, due to the CISC instruction set.... long story, i've written about this before.
Oh well :(
Just a thought -- I forget -- are EOMA68 cards permitted to protrude from the slot any, the way PCMCIA/Cardbus cards almost always did?
of course.
If so, it *may* be possible to wire up a small ventilation system -- fan with a bit of ducting is what I'm picturing, there's no room for a real heatsink in there, after all. But every little bit helps... ;)
graphite paper also helps.
