Geforce FX is 4 Pipelines and 2 TMUs
Exclusive Not 8x 1 as previously suggested
By Fuad Abazovic: Friday 21 February 2003, 19:07
IN A MARATHON INVESTIGATION that The Inquirer launched a couple of days ago, we have some solid stuff to present to you. From the time when Nvidia first questioned the validity of 3DMark03 and its single texturing as a method of rendering that is rarely used in games we knew that somthing was rotten in Denmark, sorry, Santa Clara.
An Nvidia technical marketing manager confirmed to us that Geforce FX has 4 Pipelines and 2 Texture Memory Units that can results with 8 textures per clock but only in multitexturing.
However, Nvidia did say that there were some cases where its chip can turn out 8 pixels per clock. Here is a quote:
"GeForce FX 5800 and 5800 Ultra run at 8 pixels per clock for all of the following:
a) z-rendering
b) stencil operations
c) texture operations
d) shader operations"
and
"Only color+Z rendering is done at 4 pixels per clock"
We talked with many developers and they said me that all games these days use Color + Z rendering. So all this Nvidia talk about the possibility of rendering 8 pixels in special cases becomes irrelevant.
The bottom line is that when it comes to Color + Z rendering, the GeForce FX is only half as powerful as the older Radeon 9700.
After further investigation, we learned that many games including Unreal Tournament 2003 use both single and multitexturing. In any cases where you don't need multitexturing and can make your scene with single texturing you want to do that as every bit of bandwidth you can save really counts. You don't want to lose your bandwidth just to make one graphics company happy.
We can assure you that this is just the start. We have more to present to you in the next few days. µ
