One of the major advantages of an impeller based design is that it is mostly self cleaning. The centrifugal forces on any particle (ie dust/dander/etc) that enters the vortex and the impeller area...

the air bearing is dynamic and self calibrating (at such a small gap its the only way to do it, esp when a small bump could destroy it other wise). As the impeller spins up, the friction forces...

No, no it cannot. Don't let Nvidia's marketing fool you. Counting FP16 as the same as FP32 and FP64 is complete marketing BS.

I'll bet you a fairly sizable amount of money that Intel is going to ship parts with upwards of 150w TDPs on 14nm!

Come on lets not be absurd. The number of people that really use 2 CPUs is fairly small. The number that can use 4 is smaller still. The number that can use 8 is practically non-existent.

You've managed to equate Vin with actual Core Vdd. The only think that voltage listing tells you about core voltage is basically absolutely completely nothing. In fact, using that as your point of...

No it is not at all clear. The F/V curve is of absolute relevance! So is Idsat vs Voltage.



And I think you need at least basic semiconductor theory which you are completely lacking.

The thermal limits are entirely relevant and no one knows what voltage is needed to operate at 2.6Ghz outside of Intel. And those voltages are likely to vary from chip to chip AND core to core! Its...

Apples meet oranges, oranges meet apples. Your comparison is basically irrelevant as the Core M is thermally limited. And FYI, the Core M operates in a larger voltage range than .988-1V.

All depends on what you are doing with that MCM and what the components are. For most mobile SoCs? No. It doesn't make much sense. Most are in the range of 100-150mm2. If the fab can't get...

that's not what it actually says, but good try. What it says is that Intel is currently asking 3rd parties 25% more than Samsung. It doesn't say anything about actual cost.

Total fab cost per year is going to be in the 10-14bn range at most. And that's with significantly more capacity at the leading edge than TSMC has. Generally about 2-3x.
