Or tri SLI 3 titan blacks for the price of the Z

DOnt know what nvidia smoking when they made this price but its major ripoff

 

Someone was probably like, "Hey. I know how we can make more money!"

In fairness, when you ask "How much VRAM does the Titan Z have?", then the correct answer is 12GB. There are in fact 12GB of GDDR5 on that PCB.

Obviously we're all quite aware of usable vs. present, but if Nvidia called it 6GB, some would wonder if it was 3GB per card.

Dual GPU card. 2x6gb. In market terms 12Gb.

Because it depends on the application.

This card is optimized for compute applications, in compute apps you can address each frame buffer independently.

Whoooa really? Now that's interesting.

 

But even then: For other dual-gpu cards Nvidia has had in the past, they don't advertise double the amount of Vram it can normally use, right? AMD doesn't do this I don't think. But they're doing it for the Titan Z.

All dual GPU cards in the past have been advertised with the physical amount of memory on the board. Example: GTX 690 (2gb+2gb) was advertised as a 4GB card.

3D applications can address 2GB on 690 (because all texture data must be stored on local framebuffer each) and compute applications can address each frame buffer independently.
