Last I'd heard, these were going to be competitive (if slightly better 
in both single-threaded performance and per-watt performance) of the 
Niagara T2+ series chips (i.e. what's in the T5xxx series).

That of course is dependent on me actually seeing one of these in a 
system, which I have not yet done so.  And, of course, their value is in 
how the T3 SPARC processor compares. Which I would expect to see in 
actual systems about the same time, give or take.  Then again, I can't 
say I have any more information about when either the T3 or the A2 will 
actually be available.


The real question for the A2 is how it performs in each of the possible 
categories:  IP/ethernet routing, crypto, general-use Integer, and 
general-use FP, plus any special use (i.e. SSE-style) FP.   I have yet 
to see any numbers on it.
