ISTR that the RAD750 isn't equivalent in performance to the PowerPC it was based on. It's a fair bit slower and it uses several times as much power. I vaguely remember reading some Lockheed blurb about it, but it's a couple of years ago now so the details are vague.
(searches the web a bit)
It looks like the NASA Office of Logic Design are running a seminar on the RAD750 in November. I'd strongly suggest that if anyone has the numbers you need, the guy who runs the OLD web site, Richard Katz, will probably be able to point you in the right direction.
The RAD750™ - A Radiation Hardened PowerPC™ Processor for High Performance Spaceborne Applications
R. Berger, D. Bayles, R. Borwn, S. Doyle, A. Kazemzadeh, K. Knowles, D. Moser, J. Rodgers, B. Saari, and D. Stanley BAE Systems IEEE Aerospace Conference, 2001 IEEE Proceedings. ,Volume: 5 , 10-17 March 2001, Pages:2263 - 2272 vol.5 http://klabs.org/rk/papers/processors/powerpc/rad750_2001_berger.pdf
BAE SYSTEMS has developed the RAD750™, a fully licensed radiation hardened implementation of the PowerPC 750™ microprocessor, based on the original design database. The processor is implemented in a 2.5 volt, 0.25 micron, six-layer metal CMOS technology. Employing a superscalar RISC architecture, processor performance of 240 million Dhrystone 2.1 instructions per second (MIPS) at 133 MHz is provided, while dissipating less than six watts of power. The RAD750 achieves radiation hardness of 1E-11 upsets/bit-day and is designed for use in high performance spaceborne applications. A new companion ASIC, the Power PCI, provides the bridge between the RAD750, the 33 MHz PCI backplane bus, and system memory. The Power PCI is implemented in a 3.3 volt, 0.5 micron, five-layer metal CMOS technology, and achieves radiation hardness of <1E-10 upsets/bit-day. This paper describes the implementation of both designs.
