Before
I go on explaining what some of the features are, I want to first
establish the fact that the Radeon has the most and the nicest set of
features than any other card of this generation, period. This alone, is
something that gamers should consider before deciding what video card
they want to buy. However, you should also be aware that many of the
features have to be implemented by the game developers in order to be
taken advantage of (i.e. T&L).
Some
features will take more time than others to become standard. For example, while
we are seeing more and more games taking advantage of T&L, we still have not
seen any games that have 3 textures per pixel, and this is a disadvantage to the
Radeon. This is because today's games have a maximum of 2 textures per pixel and
each of GeForce2's 4 rendering pipelines can pass 2 textures per clock. That
is a total of 8 texels per clock. However, the Radeon has 2 rendering pipelines
and each with 3 texture units, yet each pipelines will only pass 2 textures in 2
textured pixel games, meaning that the last texture unit is unused, and it will
continue to go unused until we see games that actually ha

ve that 3 textures per
pixel. Keep in mind, however, when we do start seeing games that do have it,
tables will turn, since each of GeForce2's dual texture units will end up
having to pass the lass texture to the next pipeline, and in this case that
pipeline will only render that texture, and it's second texture unit will go
unused. Again, it's all theory talk since we cannot yet test its performance in
such occasions.
The Charismatic Radeon
The
Radeon core is packed with 30 million transistors, yes not only more
than our high-end CPUs such as the Athlon and PIII, but also 5 million
more than the beast we call GeForce2. Most of it goes to work for what
ATI calls the Charisma Engine, which provides some nice features.
