TrustedReviews has put up a review on the nVidia GeForce
Go 6800. ATI has dominated high-end notebook graphics chipsets lately, a position that has proved to be very lucrative due to the increased interest in
mobile gaming. In fact it's been hard to find a notebook vendor that supplies a gaming notebook based on any technology other than ATI for some time, but that's
about to change.
 nVidia GeForce Go 6800 - Mobile Graphics Chipset
After pulling back a significant amount of mind share in the desktop
high-end graphics market, nVidia is now attacking ATI's stranglehold on the mobile graphics sector by launching
the GeForce Go
6800.
As the name would suggest, the GeForce Go 6800 is based on the
same technology as the desktop GeForce 6800 chipset. Just like the desktop
GeForce 6800 card, the GeForce Go 6800 chipset sports 12 pixel pipelines and
five vertex pipelines. There will be two flavours of Go 6800 – the basic version
will have a core clock speed of 300MHz, with 256MB of DDR memory running at
300MHz (600MHz effective). The high-end Go 6800 will sport a core frequency of
450MHz while the 256MB of GDDR3 memory will run at 600MHz (1.2GHz effective).
That said, the early samples will run a slightly lower core clock at 275MHz and
memory at 500MHz.
Just like its desktop cousin, the GeForce Go 6800 has
full support for Shader Model 3.0, so you'll be able to fire up Far Cry with the
1.3 patch and enjoy all that extra detail, while maintaining a solid frame rate.
Shader Model 3.0 inclusion, also means that the GeForce Go 6800 supports instancing – allowing massively detailed scenes to be created, while keeping the
polygon count down and consequently the frame rate up.
Surprisingly,
nVidia hasn't resorted to Low-K technology for the manufacturing process of the GeForce Go 6800. Using a Low-K dielectric process improves insulation between circuits in order to prevent cross-talk – this extra insulation means that less
power is needed and consequently less heat is produced.
