Sure it is a good vector processor but so is the G4.
Its vector performance is also aided by its much more impressive FSB. A modern interconnect (compared to the G4's MaxBus) and a decent FPU are probably the 970's strong points.
I probably can, and then some. Take a 1 GHz singe core POWER4 and compare it to a hyperthreaded dual core POWER5 at 2 GHz..
You can probably compare dual core to dual core and still see the 4x performance improvement. On the tasks IBM is measuring their SMT implementation runs 2 threads at full speed, so the POWER5 has 4 threads at double the clock rate plus various optimizations like an on-chip memory controller.

4 threads. Twice the clock. Sundry optimisations. On Chip memory controller. (Is that what the Athlon 64 has?)
If the PowerPC variety 9xx has two thirds of that then it will eat the 970 and Prescott and Athlon 64 for breakfast.
I pray to Gawd that Apple's 3 gig busting 9xx is ready by the fall.

No benchmarks yet, but IBM claims that the POWER5 series may be up to four times as fast as POWER4 systems.

Awesome. Could be. (Imagine the snap on X? )

I think this is an Opteron feature.

It wil eat current processors for breakfast.

I find you comment rather cryptic. Could you elaborate a little more?
