HPC? That is crazy talk. I expect this Macroscalar processor to be used in an iPad, not a Cray. I don't care about the dinosaurs roaming the IT dept.

Apple trademark may hint at processing improvement for next-gen A6 processor

I am on record that ARM is just a stopgap processor until Apple can come up with something actually designed for high performance AT LOW POWER. ARM is a failed high complexity desktop CPU that just happened to get redesigned for low power as those were the only customers ARM could find.
The next Atom will have no problems competing with ARM on performance per watt, despite carrying the dead weight of a huge instruction decoder.
Intel has the talent, OoO experience, and cubic dollars for Perf/Watt against ARM. (I do expect Intel to fail on Perf/Dollars, ultimately staying irrelevant in ARM's markets.)

Macroscalar is kinda pointless on a CPU with a ~100 instruction OoO window running hand optimized code. For an embedded CPU things are more interesting, and outside my knowledge base. ;(
