Is this for real? Can anybody confirm this info (CELL info)

Even if CELL PUs are 970 based there's nothing in that comment we didn't expect. We already know A|SPUs are SIMD stream processors along the lines of PS2 vector units.We already know they can 'talk' each other and with the central core..so..what's the big deal?

Whether this is legit or not Cells cores will almost certainly use a VMX like instruction set, same could be said about EE's VUs, but calling it VMX on steroids is slightly misleading ... VMX still depends on the thread of execution supplied by a huge superscalar core, the vector unit can only ever make up a small part of said core. Giving the vector units their own threads of execution lets you put more power in less area than you could by just using multiple superscalar cores with VMX, that is a pretty big difference.

Ok so let me get this straight, the Xbox2 CPU will have 3 Double core Powerwhatever cores, which are the same cores as the Cell ones.

So, if i'm not getting things horribly wrong, unless the BE has a lot more cores than the XCPU, at whatever cost they will be, the 2 will be quite identical...? :?

No. Cell's power seems to lie in its APUs, not the PUs (the 970s).

All those flop estimations you've seen are based off the APUs alone and don't count the PU.

Oh ok, so i did miss something.

Actually a lot of people can't grasp this idea..I don't know why.
