Nvidia confirms the GTX 580

[Sn0wm@n]

Nope, not a dual chip card, but a single chip developed from GF104 mArch, expanded 50% upward in execution units count to be exactly, taking advantage of GF104 gaming focused mArch design (much slower DP throughput, but much faster SP throughput with double Special Functioning Units & TMUs per SIMD array that what were important for gaming purpose).

A dual chip card using full fledged GF104/114 has lost meaning since AMD is determined to built Cayman based dual GPU card (Antilles). It doesn't serve you any good if your dual chip, flagship card is totally uncompetitive against its peer/direct competitor. The king of the hill slot belongs to AMD in this 40 nm round with Antilles, and i think nVidia knows it. GTX 580 still has a (long) shot against Cayman XT, but dual GF104/114 (GTX 595 ?) card will fall flat on its rear if nVidia ever dare to put it against Antilles. UNLESS, nVidia knew that GTX 580 is slower than Cayman XT, while GTX 595 could match or beat AMD's best single chip in some cases. Then GTX 595 can serve its purpose as fanboi epeen edition card.

ahhh it makes sense .. so a full on single GF104 modified die could do it ... but how long would an architecture rework of that kind could take is the difference between doing it on 40nm or waiting for 28nm and having something combative ....

When I said they need a shrink for a achieve a "real" new generation, you where making all kind of funny comments with , etc .. How comes you have turned 180' now?

It's will be big a challenge to deliver the performance/power that we expect from new generation without a shrink , both for AMD and nVidia.

As said before, the flexibility of the "old" architecture will deside the outcome between GTX 580 and Cayman.

huh ... i havent turned 180 .... i only asked if the specs spurindonesia wrote were merely possible if they rework the chip ... like rework the architecture and cut some things down to make it possible for a modified dual 460 to even pull those 576 shaders or so he said about ...


no mention of me saying its ok to rebrand ... .but now i understood that he meant a fully reworked single GF104 .. as in expended enough to call it a new gen ... but 580 doesnt diserve the new gen name if its only a 480 with the full 512 shaders ....


its a simple respin only ... and that doesnt diserve a new gen name ... an evolution of the architecture would ... and that reworked GF104 that spurindonesia hinted at would get my vote as a new gen puppy if it does this ... wich i doubt they would .. but anything is possible in that business
