6800 GT core is built on TSMC's 0.13 micron manufacturing process, and contains
a massive 222 million transistors. The 6800GT core has 16 fully functional rendering
pipelines, and is backed with 256MB of DDR III memory running on a 256bit bus.
The core is clocked at 350MHz, and the memory runs at 1GHz.
nVidia still employ the same flip chip packaging, but this
time around there's no copper heatspreader overtop of the silicon.
Instead, there is a small shim around
the outside of the package to prevent damage to the core, or miniature electrical components which dot the package
III memory is not known to generate as much heat as DDR-2 RAM, the thermal package Albatron are using on the 6800GT does have its own dedicated section
for the memory. Under this heatsinks we find Samsung K4J5532QF-GC20 DDRIII
DRAM modules, which are clocked at a nice round 1 GHz. For more information on

IQ, now we're talking image
In the last couple of years there's been a lot of talk about
videocards and image quality, and whose solution is best. After all, what good
are fast framerates when everything is a pixilated blur? This was one obvious area
where nVIDIA needed to improve, so let's see if they've done their jobs right this time
around. For comparisons sake, we're going to illustrate the graphical quality of the
Albatron GeForce 6800GT versus the ATi based X800XT PE.

The wing of
the second plane seems just a bit sharper on the X800XT PE videocard than
on the 6800GT. Anisotropic Filtering is almost identical on both platforms, and
you'll notice that nVidia can handle 16x AF. With both AA and AF enabled, both cards produce
excellent image quality, and I don't suspect any differences will really be noticeable during
