Nvidia Corp., a leading supplier of graphics technologies and core-logic sets, announced on Thursday its new GeForce Go 7700 visual processing unit, which is the world’s first graphics chip produced using 80nm process technology, the thinnest fabrication process used for manufacturing of graphics processing units (GPUs).
The GeForce Go 7700 features 12 pixel processors and operates at 450MHz, 128-bit memory controller, up to 512MB of memory at 1000MHz clock-speed. Given that Nvidia’s web-site has one page for the GeForce Go 7600 and Go 7700 models, it is highly likely that there is no difference between the GeForce Go 7600 and GeForce Go 7700 apart from manufacturing process – 80nm for the Go 7700 and 90nm for the Go 7600 – and some performance differences.
According to Nvidia’s web-site, the Go 7700 is faster compared to the Go 7600, but is not as fast as the Go 7600 GT model. There are no approximate thermal design power differences or power consumption differences noted by Nvidia, even though thinner fabrication process usually means a bit lower energy consumption. Additionally, thinner manufacturing processes allow developers to manufacture the chips in a more cost-efficient way, which may benefit end-users in terms of lower pricing.

Nvidia Unveils World’s First 80nm Chip
Should be "Nvidia Unveils World’s First 80nm GPU Chip" to lesson any confusion :p.
much liek you can't compåare Intel and AMD by size and power used and such, only moreso.
I believe it means GPU, not CPU. There are currently no 80nm GPU's on the market.

it was a joke
BTW, X-bit Labs made a mistake by calling the GeForce Go 7700 the same thing as the GeForce Go 7600. The Go 7600 is actually an 8 pixel pipeline part (pretty much a GeForce 6600 GT), while the Go 7700 is a 12 pixel pipeline chip (pretty much a GeForce 7600 GS). It is a completely new mobile GPU, not just a simple die shrink.
And in case you were wondering, the GeForce Go 7900 GTX has all 24 pixel pipelines, as well as slightly increased clockspeeds over the GeForce Go 7900 GS, making it the top-dog in notebook GPUs.
Those are X-bit Labs words, not NVIDIA's. Since they also say it is just a die shrink of the GeForce Go 7600, which again is not true, I can't completely trust what they say. But I am 99% sure it has a 128-bit memory interface either way.
