The Highlights
4 Way (8 cores) 20120 SAPs
8 way (16 cores) 40070 SAPs
2 Way (4 Cores) 10180 SAPs
In comparison
Intel Itanium 4 Way (8 core) 8680 SAPs
AMD 4 Way opteron (8 core) 10120 SAPs
Intel 2 Way Xeon core 2 arch (8 core) 9000 SAPs
My thoughts. Per core the IBM beats anything out there.
Per Socket Quad core Barcelona could match it (SAP scales very well with CPU cores)
Itanium really is in a bad state.
Core 2 arch needs to scale to 4+ sockets
Within this benchmark Opteron is faster per core than core 2, IMC is the main reason here. Good hopes for barcelona
While impressive, something to keep in mind is just how large the Power6 processor is. It's 341mm^2 with 790 million transistors on 65nm for only two cores. Core 2 Duo is only 291 million transistors for two cores, or 582 million for four cores (which gets close to P6's numbers).
The Power6 transistor count excludes the 32MB of off-die L3 as well.
While I'm not saying Power6 is bad, on a per-transistor basis, it's on par with current generation x86 processors like AMD's and Intel's. The only dog in the group is the itanium, but that comes to no surprise to anyone.
I am very interested to get the 1st FPU benchmarks... and I am interested to know how does it fare with non integer pointer incrementation. Usually Power arch really sucks at doing casting from float to int.

Wow, it's twice as fast as a 4P Opteron. Even Itanium couldn't knock off the 4P Opteron. I would say that Barcelona will get close at it's highest clock. It may even surpass it because of L3 and HT3.
It'll be interesting. Next week is Computex and at least BioStar is reporting they will demo Agena in AM2+. AMD should actually reveal clocks and benches.
At least that's the last I heard. They can't afford not to.
