How about 448 GB/s memory bandwith?

The newly introduced 1Gb GDDR5 is built on the company’s leading edge 54 nanometer process technology. It operates at the fastest speed of 7Gbps which is 40% improved compared to 5Gbps GDDR5 and processes up to 28 Gigabytes of data per second with a 32-bit I/O. In addition to its improved speed, it is also designed to minimize power consumption at 1.35V power supply. This fast speed of graphics memory product is ideal in high end applications such as game PC, game console and graphic cards.

Wouldn't it be ironic if it turns out all the new GPU designs arriving in the next 18 months use tiled rendering, massively reducing the need for bandwidth?

Where would be the problem? High-end could move back to 128-bit, while reducing PCB complexity and power usage.

Not a problem, just a bit of sweet irony. It might be another generation before the IHVs adapt bus widths downwards to take advantage.

One area this would be really tasty is with a CPU+GPU single-die processor. Years away, though...

I'm sure developers could find a way to use it if it was available.
