The shining point of GeForce3 at
present tnaw_xtennis 2001.03.02
With the feature of full DirectX 8.0 compliant, GeForce3 will be undoubtedly a great video card for tomorrow. The core/memory speeds of GeForce3 (200MHz/230MHz) are no any faster than those of GeForce2 Ultra (250MHz/230MHz), still GeForce3 that ties to its innovation antialiasing and memory architecture brings end user nowadays a praiseworthy performance boost over GeForc2 Ultra.
The antialiasing performance is the most shining point of GeForce3. Benefit by both of the Quincunx AA mode and the high profitability memory bandwidth interface
(Table 1.), GeForce3 run today games with Quincunx antialiasing enabled almost twice as fast as the GeForce2 Ultra with 4xFSAA(Supersampling) under the same situation
(Table 2.). It is interesting to note that the new memory bandwidth interface to be extremely in favor of antialiasing fulfillment of GeForce3. The known benchmarking results
(Table 2.) show that there is about +10% performance boost of GeForce3 over GeForce2 Ultra under the normal conditions, while we get a performance boost as high as over +50% with antialiasing enabled.
Crossbar Memory Controller ( Memory controller that is optimized for accessing data with
a fine granularity access pattern, ensuring that less fractions of the memory bandwidth is wasted when
accessing small datasets. )
1 : 1
4 : 1
Lossless Z Compression ( 4:1 lossless data compresses and decompresses by video chip hardware
in real time, thus the memory bandwidth consumed by Z-buffer traffic is reduced
by a factor of four. )
4 : 1
Z-Occlusion Culling ( A hidden surface removal (HSR) rendering mechanism
that reduces memory bandwidth requirements by avoiding having to access pixels
that would not be visible. )
it can demonstrate as much as four times the
performance of traditional rendering mechanism, while in practice the typical benefit of
it averages a 50%-100% improvement.
