Bulldozer Questions from an Intel User.

post #1 of 162
Thread Starter 
I know not much is known about this chipset yet at all, that having been said, I have a few questions:

1) The 8 core statistic on the higher end Zambezi FX chips...is this 8 REAL cores, or is it like Intel's Hyperthreading?

2) Is it possible to put multiple FX chips on a single board, or does AMD do things the same as Intel where consumer level stuff will not intercommunicate and you need the professional level chips (Xeon/Opteron) to run on multi proc boards?

I have zero loyalty to Intel whatsoever...in fact I'd likely be more inclined to go with AMD to spite them, ESPECIALLY on their more high end chips just to cast my dollar vote towards increasing the competition.

Just wanted to clear up those couple main questions I had if anyone knows anything yet about this.

1) - It's 8 actual, physical Cores.

2) No. You need the server variant.

Okay thanks guys, very helpful.

Still not sure what to make of the 8 cores thing though in terms of whether or not it will actually be better at rendering CG images than a Sandy Bridge proc.

Does anyone have any info about AMD's next server processor release? Right now I'm waiting on the Sandy Bridge Xeon e5 chips to make a dual proc workstation...wondering if maybe AMD will bring out something soonish as well.

Lol, hes probably taking a 99.9999% educational guess though. I'm sure that info would have leaked by now if we could use more then one chip on consumer boards.

I'm pretty sure JF-AMD has said that already, and most likely you wont be able to because you never can.

1) It's 8 real cores. HOWEVER what they consider a single "core" is an Integer core. Rather than 1 Integer core and 1 Floating point core (like in most conventional designs) it's 2 Integer cores for every 1 Floating point. It's weird to understand but just accept it. It's a new architecture and they are gambling a lot but I think it might pay off. I'm reserving judgment until solid benches come out.

2) I don't know of any consumer level 2P boards. You'd have to wait until Q3/11 for the Opteron BD chips to come out (they will be on C32 and G34 sockets).

Personally I'm going to wait and see what happens with BD. If it's good then I'll upgrade but if not I have the 955 to placate me until Intels next design or Enhanced/NextGen BD comes out.

No, it's not. It's one interger with one floating point, but the two floating points in a module can work as one.

No its not, its like 80% of a real core, per core. The FP part of the chip is shared, as well as the some levels of cache, and a few other things.

Each core has its own 128 bit FP unit, however they can combine to create one 256 bit FPU unit. So the 8 core (4 modules) chip will have 8 128 bit FP units, that can combine as needed to have 4 256 bit FP units.
