There is a 'titanic' shift in semiconductor designs that Microsoft is interested. Mainly, surface cmos circuits or buried cmos circuits. The speed is night and day in favour of surface circuits produced by ion deposition with much less linewidth and layer thickness, avoiding wet chemicals. The buried circuits fill up holes, and use wet chemicals to do chemical mechanical copper polish(highK gates). Which can not be more precise in structure tolerances. So, the cpus are limited to 3.8 ghz. Surface cmos circuits are being developed upto 75 ghz target.

Further more, the data processing of multicores can be 8 bit(ascii data streams) instead of batched branch prediction data processing of 32 bit multicores. 4 word batched processing(21 stages) is slow.

For the next few years, we are going to see ultra low core voltages(microvolts or nanovolts) to make computers without too much heat or using too much electrical power.

So be it. But then, Java may want to sell to Microsoft instead of IBM?
