Sapphire Toxic Radeon HD 7970 with 6GB Memory Showcased

The fact that Sapphire has been working on a Radeon HD 7970 graphics card with an obscene 6 GB of memory has been known since the end of 2011. The said card, the Sapphire Toxic HD 7970 6GB, has already taken shape, and was spotted running at CeBIT. Such as it is, AMD utilizes 2 Gbit GDDR5 memory chips in numbers of 12 to achieve 3 GB of memory across a 384-bit wide memory interface, on its HD 7970. Higher density GDDR5 chips are not available, at least not in bulk. So the only way Sapphire is doing 6 GB is by piggy-backing two 2 Gbit chips across 32-bit wide paths, each. As a result, these cards have memory chips on both sides of the PCB, obverse and reverse, and require a metal back-plate to keep the chips on the reverse side cool. The only reason we see consumers needing 6 GB of video memory today, is multi-monitor gaming. Even there, the impact of the increase to 6 GB memory (from 3 GB) is debatable.

Considering how close I got to running out of vram on my 580 3GB I could see this being useful not too far off.

Really? Which games? Settings? Resolution?
I like to know too. Which games/programs?
Thanks.

Also 6GB is both pushing technology forward but also a marketing plot.
