In general, MIPS and PowerPC processors are favored over Intel parts
because
of power vs performance metrics. Intel parts deliver lots of performance
but
put a heavy burden on the designers trying to get the heat out.

Intel went out of the Mil-Spec processor business and Motorola kept making
them. The Mil-Spec components specifications were abandoned in place in
2000 and Intel had no incintive to continue to support a fantasy world.

The main issues in using commercial parts in military applications are 1.
Quality level, 2. Operating temperature range and 3. Packaging.

AKA the Rome data, as based on the RPL Model. RL has a pretty nice software
reliabilty model as well, but of course the F-22 was to early for COTS. I
am optimistic about the F-35, with it's injection of the RPL model.
