3D Blaster Annihilator Pro review

Labs Product: 3D
Graphics Processing Unit, aka the GPU, is the biggest feature
of a GeForce board. The GeForce 256 can do a lot of the
calculations normally done by the CPU and do them with the GPU.
may not be many software titles to take advantage of the GPU
at this time, but support is growing. The OpenGL API used in
NVIDIA’s reference drivers already have support for some of
the GPU processing power, so on top of high fill rates you
also get some acceleration due to the GPU being used. The
features that the GeForce 256 GPU tout is what is known as
and Lighting is what the CPU, in the past, took care of. Now,
when software is written to take advantage of T&L through
the GPU, the CPU will no longer be used in these tasks and can
do other things such as working with the AI (artificial
intelligence) for a game.
GeForce DDR cards are clocked at 120MHz for the core and
300MHz (150MHz + DDR) for the memory. This is a lot lower than
the clock speeds that the TNT2 and TNT2 Ultras have. There is
a reason for this though. The GeForce actually uses a smaller
die size than the TNT2s have, but the GPU is a very complex
architecture. The GPU is so complex, that 22 million
transistors are used in the core. With 22 million transistors,
heat can build up very fast and the heat may not be dissipated
fast enough to run at speeds higher than 120MHz. Some sites
have reported that the GeForce can run up to 70 degrees
Celsius. This is very true. In my experience with the Creative
Labs Annihilator Pro, I have measured temps at 65 degrees
Celsius on the back of the card with an external diode probe.
That is very hot indeed.
of the board was a breeze, just as it should be. I took out
the Creative Labs Annihilator and put in the Creative Labs
Annihilator Pro. It booted into windows without me even having
to reinstall the drivers, since it just redetected the card as
a GeForce DDR and continued using the drivers for the GeForce
made by Creative Labs are very similar to that of the
reference drivers made by Nvidia. The main difference you will
see between the reference and the Creative drivers are looks.
I find that the reference drivers to better for me though,
since the reference drivers allow for both clock speed and
memory overclocking. The Creative drivers only allow you to
overclock the memory on the card.
