Does anyone have any information about the upcoming POWER6 family?

yes it is a bloody impressive chip
0.8V 65nm and 5GHz

LOL
... and Apple now uses Pentiums Smile

Yep apple suck.

I dont know why you'd move away from a full RISC based machine to CISC?? Do they want market share that badly???

I've deployed a few of the Mac Pro's at work, there not bad.... but they still under perform the PPC versions which are almost 3 years old.

X86 =< PPC

Core2duo is full RISC (as is P3 and P4)

AMD Athlon 64 is RISC too. AMD is RISC from K5 to present day. Am I right ?

Ah no, Intel processors use a hybrid CISC/RISC architecture. Interally they process RISC base instructions but a CISC/RISC decoder is used to convert the frontside operation which only accpets CISC instructions.

This is done for compatibility with the x86 architecture. Something which AMD also does.

sure, but POWER6 is by far not pure RISC either (very few modern RISC CPU's truly are. they have a very large selection of instructions, and often do not have basic features that make RISC RISC (such as fixed instruction length, and pure load/store architecture.)

Why don't 'YOU' consider it RISC?

As I remember newest PowerPC has
a) instruction with fixed length
b) a lot of registers in opposite to classical x86.
...
z) IBM said that PowePC is RISC. I think that they have reasons for it.
So we can consider it as RISC Smile

hehe never said it wasnt RISC, just that it isnt RISC in true from, (though what is today? except for perhaps MIPS)

But it is a truth RISC based procesors, I mean unless you know more about RISC then IBM does...

has something to do with POWER (Performance Optimization With Enhanced RISC)???
