Introduction
You
would have to be completely blind (or hiding under
a very large rock) to have missed the rapid
increase in specification and performance of the
3D graphics cards on the commercial market in the
last few years. Graphics cards today are capable
of rendering graphics in real-time that would have
taken hours to render as a movie only 5 years ago.
Being
part of the graphics/multimedia community, we
programmers are pretty much solely responsible for
continuing to push the envelope to see what these
stunning piece of hardware can do. Likewise, the
engineers behind these graphics cards are
continually raising the possibilities. People
weren't joking when they said that graphics cards
advance at moore's law cubed!
If
you are serious about games development then
you're going to need a fairly fat wallet to stay
on the cutting edge of development, which, lets
face it - not many people can fork out $350 every
6 months for a new 'toy'. So, when it comes to
choosing a new graphics card for your system, you
really do want to think seriously about it - is
this card going to be useful in 6 months time? is
this card going to revolutionize the way I write
my programs? how much is it going to benefit my
current programs?
Because
us programmers are so reliant on our hardware when
it comes to creating eye-popping visual candy, you
really need a review that goes one-step beyond a
long list of games statistics and benchmark
values. This is why I wrote this review, to answer
the questions (from developers) that aren't
usually answered by standard run-of-the-mill
reviews.
The
Current State Of Play
As
I already mentioned, the consumer graphics card
market moves at a pace that makes the rest of the
computer industry look slow. Therefore, if you're
reading this more than 2 or 3 months after I wrote
this (May 2002) then it is quite possible that
there will be a whole new breed of graphics cards
available that will make the Radeon reviewed here
look pathetic.
For
the last year or so, the consumer market has been
dominated by 2 main companies - ATI
and NVidia,
both of which have been constantly battling both
on the price front as well as who's got the
latest-and-greatest technology. The constant
price-war all across the spectrum is only a good
thing for us consumers - cheaper, more powerful
cards. However, the constantly improving
technology means that even if we only paid
bargain-prices for our hardware, it'll be far from
the best within a matter of months.
At
the time of writing it looks like the graphics
card market is starting to heat up again - with Matrox
recently revealing the 'Parhelia-512' and Creative
announcing it's bringing 3DLabs technology down to
the consumer level. Details of both these cards
are currently a little unclear, but if you search
around you can probably find any details you might
want.
The
Three Phases of 3D
In
previous years you could refer to different cards
by 'generation' - each of the major players would
usually release it's top-line card in response to
one of the other companies, thus often all
appearing quite close together, and because they
were all fairly similar you could batch them
together as 1st, 2nd, 3rd,
4th etc.. generation cards.
This
doesn't work very well anymore - mostly due to the
regular releases of major new chipsets, and the
relentless tweaks and slightly improved minor
versions. I've found one way of dividing all the
cards from the last 5 years into three categories:
1.
Basic 3D cards
These were the very first generations - nothing
more than triangle-drawing monsters. Examples
range from the ancient 3DFX Voodoo 1's and 2's,
the TNT series from NVidia and the Rage series
from ATI.
2.
The GPU, stage 1
This is probably where things really started
rocketing skywards. With the release of the NVidia
GeForce 256 a considerable amount of the rendering
pipeline was offloaded onto the graphics card in
the form of hardware transform and lighting
("T&L"). ATI and NVidia were the
only main players left at this point - 3DFX did
release the Voodoo 4's and 5's, but they
disappeared quietly and then so did the whole
company! These graphics cards were mainly
Direct3D7 parts.
3.
The GPU, Stage 2
This is the stage where we currently are, fully
DirectX 8.0 or 8.1 compatible graphics cards.
These cards tend to be defined by their ability to
use hardware shader's (more on these later). At
the time of writing, it's still pretty much a
battle between ATI and NVidia - with the Radeon
8500 series cards being ATI's flagship and the
GeForce 3 and 4's being NVidia's.
Chipset
Overview
So,
for this review we have one of the (currently)
most powerful pieces of graphics hardware to ever
grace the personal computer. What exactly are its
specifications then?
The
Radeon 8500 chip
- 250mhz core speed for the 'LE' models and
275mhz core speed for normal models
- A fully compatible D3D8.1 component
- 128mb or 64mb of video memory running at
250mhz (500mhz DDR) on the 'LE' chips, and 275mhz
(550mhz DDR) on normal models.
- TruFormtm, ATI's high-order
surface / on-chip tessellation engine.
- SmartShadertm technology -
high-performance pixel shaders with a large
feature set
- HyperZ IItm - the 2nd
version of their memory bandwidth optimizer /
Z-Buffer optimization
- SmoothVisiontm, ATI's
implementation of Full Screen Anti-Aliasing
I'm
sure they could fit a few more trademarked (tm)
features in there somewhere, but I suppose 4 will
have to do for now!
All
in all, it's a pretty loaded chipset, the
generally faster chip and the inclusion of 128mb
of video memory on board is frightening on its
own. Just think, only 2 years ago 128mb was a
fairly average amount of memory for an ENTIRE
computer, let alone just the video sub-system.
I
shall cover each of the major areas above in more
detail later in the review.
Available
Variations
As
with all major releases of 3D cards, there are
always several versions available - going from the
stupidly expensive down to the relatively cheap.
ATI's Radeon 8500 series is no different. Up until
fairly recently ATI has been the sole manufacturer
and distributor of cards based on it's chipsets,
but they've recently started supplying chips to
other 3rd party manufacturers. The following list
is a basic run-down of the main available
variations - bare in mind that different companies
may offer different additional items (software
bundles etc...), I'm focusing on the actual video
cards for now:
ALL IN WONDER RADEON 8500DV
RADEON 8500 128MB
RADEON 8500 64MB
RADEON 8500LE
I've not listed
prices for each version simply because they will
change very rapidly - but at time of writing
you'll be looking at paying $150 and above
depending.
The two plain
8500 models (listed 2nd and 3rd above) are the
faster variants, the 8500LE (reviewed here) is the
first to have the full 128mb of memory, and the
8500DV is the version with all the input and
output connectors.
