. I can't stop laughing at how amateur of a fake this is.
Its not even remotely possible, between this and the lack of hotclocking. 1.75gb is also not possible, and the GK114 (GTX 690) is also supposed to be either a 384 bit or 512 bit memory bus.
While the chart is truly most likely a fake (I'll give ya that), you still have no idea what you're talking about though.
Obviously, 1,75GB in this chart is refered to 1792 MB just like 1,5GB is refered to 1536MB.
1792MB along with a 448 Bit bus would be perfectly possible even with a clean bus width (1792 / 448 = 4).
Even if the chart would be fake, a GTX 690 as it stands there would be perfectly possible too as opposed to what you are saying.
The GTX 295 when it was released was a mixture between a GTX 260 and 280
It had 240 Shaders on each GPU (GTX 280) but
only featured a 896MB VRAM along with 448Bit bus interface (GTX 260). (Note: the GTX 280 had 1024MB and 512 Bit)
Eventually, half a year later they released the mixed GPU as GTX 275.
So yes, 2x1024SP (GTX 680) with 1792MB and 448 Bit (GTX 670) would be perfectly possible IF the chart was true, it would be based on two hypothetical GTX 675s.
Turns out you're the amateur after all :>Edited by toX0rz - 2/3/12 at 12:33am
