ATi Radeon 9000 Pro - reference review |
With the Radeon 9000 announcement you need to
keep in mind that actually two new products within that 9000 range have been
born. The Radeon 9000 and the 9000 Pro. As you can guess the Pro is the faster
one and also the one we are testing.
Besides everything you need in these videocards
ATI focuses a lot on the following features:
- Quad-pipe architecture: Four parallel
rendering pipelines power the applications with high speed. Four texturing
pipelines pumping textures into triangles
animated by a hardware Vertex Shader and achieves per pixel programmable
effects through a hardware Pixel Shader.
- Hardware Vertex Shader (v1.1) to handle
on-board the massive geometric complexity of new games.
- Programmable pixel (v1.4) and vertex shaders:
Which in one word ATI's calls SmartShader technology. Basically it takes
advantage of the advanced features in Microsoft DirectX 8.1 and means even the
newest and most advanced 3D games will be fully supported. No DirectX9
hardware features Like pixel and Vertex 2.0 shaders though. That's where the
Radeon 9700 comes in.
- Pixel Shader to add per pixel shadows as
that help create life-like textures and to create the most realistic finest
water and lighting effects on the smallest of objects, such as fur, hair, or
blades of grass
- Multiple display architecture supported by
Hydravision ATI's desktop management software enabling productive and
effective use of multiple displays.
- New Fullstream technology leverages pixel
shaders to accelerate video and improve the quality and scalability of
streaming video. Something I'm quite excited about.
- Solid video playback hardware, which
decodes MPEG2 for DVD, de-interlaces video for display on a TV and enhances
online video playback. The 3D Prophet 9000 series means faster games, and
finer realistic texturing effects, thanks to its large texturing engine and
its? the hardware acceleration of Microsoft DirectX 8 API hardware
acceleration.
If you are thinking that the Radeon 9000 is a
cheap runoff of the Radeon 8500 then you are wrong. This is a new silicon
designed in a way it will keep production costs low. Fewer transistors and
a cut down that
handles 1 texel per cycle. As result this means higher production yields and thus cost reduction. The word
castrated
pixel pipelines just popped into my mind ;)
Just like the Radeon 8500 the
Radeon 9000 has four pixel pipelines. However, as just stated, they can
only calculate 1 texel per cycle compared to two on the Radeon 8500. To
compromise this the end pixel increases
from three to six. Rather confusing but basically the outcome of this means that
the Radeon 9000 in theory is slower than a Radeon 8500 in games with
multi-texturing and the benchmarks will back that theory up.
The main difference between the normal and the
Pro version basically boils down to performance. To get you an idea where the
product is compared to the competition take a look at this table:

ATI is shipping a Radeon 9000 Pro graphics
card, featuring 64MB of DDR memory and dual-display support including DVI-I, VGA
and TV-out with a suggested retail price of 149 USD while Creative Asia will
sell them for 129 USD. I expect within a month that the 64Mb model will sell for
about 100 USD.
