קצת מידע על הכרטיס המדובר
להלן ההבדלים בכרטיסי המסך של ה GeForce FX 5900
GeForce FX 5900
Only a few months after the introduction of the previous
top model, the 0.13μ GeForce FX 5800
( NV30),NVIDIA replaced the heavily criticized card
(loud cooling solution, great heat dissipation, too low
memory bandwidth) with the FX 5900 (NV35). In
addition to re-designing the reference cooling solution
so it is much quieter,NVIDIA also decided to
drop the very hot DDR II memory on this card,
instead widening the memory bus to 256 bits. 3D
features saw only minor improvements or tweaks
(Color Compression and floating-point performance,
UltraShadow feature). Of note is the fact that the FX
5900 Ultra chip is clocked 50MHz slower than the
FX 5800 Ultra. In exchange, the memory bandwidth
grew from 16.7 GB/s to a very impressive 27.2
GB/ s.The number of transistors also increased slightly,
from about 125 million to 130 million.
Obviously, the FX 5900 Ultra is the fastest card of
the family. Since the Ultra ve rsion is only available in
a 256 MB configuration, it is also the most expensive
of the bunch. 128 MB and a lower price might have
made more sense in making the card more attractive.
The non-Ultra version runs at slightly lower clock
speeds,while the GeForce FX 5900 XT seems to
offer the best price to performance ratio. Although
running at lower frequencies than the two faster
models, it offers the full feature set.
Versions:
GeForceFX 5900 XT - 128 MB - 256-bit -
400/700 MHz
GeForceFX 5900 - 128 MB - 256 Bit - 400/850
MHz
GeForceFX 5900 Ultra - 256 MB - 256-bit -
450/850 MHz
