Back at MacWorld Expo in July, we were lucky enough to get a preview of the new
ATI Radeon Mac Edition AGP video card, and we were astounded by the claims of the
card’s estimated performance specs at the show. Although some people were disappointed
that the card was not listed as a build-to-order option for the new G4 MP machines
that Apple was shipping at the time, the consensus was that there was definite interest
in the product come the shipping date. Just outside of the small room where we had
our meeting with the ATI representatives, there was a constant buzz around the demo
machine running Quake 3 Arena and we have been waiting for the past three months
to get our hands on the new Radeon video card. Over the
past week we have been putting it through our rigorous tests, and have come up with
some interesting results.
Upon taking the Radeon out of its box, we noticed that the physical size of the card
was comparable to the size of the current ATI Rage Pro shipping in the current G4
machines. The reason I’m mentioning this is because the Radeon’s main competition,
the Voodoo 5-5500 is over twice as long, not to mention, covered with two large fans
to help dissipate the heat from the chips which may requires an available power connector
to run. With the Radeon, all we had to do was open the side of the case, remove the
existing Rage Pro card, and insert the new card in the slot, and we were ready to
go. The fan that is built onto the card requires no extraneous connectors, and for
the most part creates little to no noticeable noise inside the case. The external
connectors on the Radeon include the standard VGA, DVI-I for digital flat panels,
and TV-Out via an S-Video connector. We’ll go into more detail later about the connectors,
but for now, on to the completion of the installation procedure. After the initial
boot, we installed the ATI software that was not much different than the existing
ATI universal drivers, except made for the Radeon, and OpenGL 1.1.5, which is required
for most of the 3D operations of the card. After a quick reboot, we were up and running
with no extra configuration needed. If there is a need to do so, the ATI Displays
control panel is easy to navigate, and is pretty much self-explanatory. The included
manual is clear and concise, and has step by step directions for a more in-depth
understanding of the Radeon’s inner workings. On a side note, we tested the Radeon
with the OS X Public Beta, and it worked without any noticeable problems, although
under the current beta limitations, we did not have any OpenGL support for the card,
which also means there is no hardware support for rendering engines.
The first application that we tried out on the new Radeon was the Apple DVD Player.
We threw in a copy of The Matrix, loaded up the chapter where they were going into
the building to save Morphius, and let it go. With my PowerBook, at times I noticed
some video stuttering in this part of the movie when I am running in full screen
mode. I figured that if we got through the sequence with no major problems, I would
be happy. The Radeon Video Immersion technology promotes on-chip motion compensation,
run-level decode, de-zigzag and IDCT hardware acceleration of MPEG-2 decoding for
a nearly perfect picture. Needless to say, the Radeon passed with flying colors and
not once did it stutter. A side note is that the Voodoo 5-5500 does NOT offer DVD
decoding, and therefore does not support DVD playback on your desktop. If you decide
to go with the current PCI version of the Voodoo, you can use your existing Rage
Pro for the video playback. If you choose to wait for the AGP version of the Voodoo
5-5500, I believe that there is again no planned DVD support on the card, which removes
functionality of one of the coolest features
of the G4. When ATI ships the PCI version of the Radeon, DVD support will be included,
provided you have a DVD-ROM drive. The bottom line is, the ATI Radeon offers great
3D and 2D ability and the DVD support that current G4 owners expect, where the other
cards fall short. Now if you aren’t watching a DVD, but are still interested in video
editing and QuickTime playback, the Radeon has just the thing for you.
The Radeon uses special hardware techniques such as alpha blending and chroma
interpolation to enhance video quality instead of replacing pixels. For the Radeon’s
hardware to kick in, the QuickTime file that you are viewing must be in either MPEG-1,
Cinepak, or Indeo format. Although ATI states that the Radeon’s hardware works with
the above formats, that does not mean that other movies compressed with codecs such
as Sorenson Video look bad, they just can’t be hardware accelerated. With the DVI-I
connector, you can plug in your digital flat panel display to the Radeon. Back when
we ordered the MP G4, there was no build-to-order option with the Radeon, so we have
to wait until we get our video adapter to hook up the Cinema Display. The last feature
is that with the included Mac2TV Video Out (S-Video) feature, you can output the
display of your desktop to a TV or VCR for uses such as recording presentations,
and playing Quake 3 Arena on a 61 inch TV. On a final note, there is good news if
you are one of those people who did purchase an ATI Rage Orion, or one of the other
ATI cards, ATI says that it will support the Radeon in its Loyalty Upgrade Program.
More than likely, if you are interested in the ATI Radeon card, you are interested
in it because of its 3D and gaming abilities. I’m not saying that the 2D acceleration
is immaterial, but the strengths of this card lie heavily with its 3D rendering and
gaming abilities. If you ask me if it’s worth the $99 build-to-order option, I would
definitely say yes for a few reasons. Firstly, the ATI Rage Pro was a great performance
card for its time. The Rage Pro has been out for close to two years now, and although
it’s a strong contender, the technology is dated. Consumers wondered if the ATI Radeon
would be worth the wait, and honestly, I believe so. For the seasoned gamer, this
card is the answer to your high-resolution prayers.
I believe that the true test of the Radeon’s horsepower comes in the display of
its 3D gaming and rendering abilities. We focused on two games, Quake 3 Arena, and
Unreal Tournament, and one 3D rendering benchmark; CineBench 2000. Although CineBench
did not give us any staggering results, there are few exceptions to the rule, and
most of them lie on the PC/Windows NT side of the coin. Quake 3 Arena was used because
of the almost industry standard "TimeDemo 001"
test for frames per second (FPS), and Unreal Tournament because of the inclusion
of RAVE hardware acceleration into the game itself. But enough of the talking; let’s
get on with the games.
Benchmarks were performed on an MP G4-500 with 512 MB of RA and a minimal install
of Mac OS 9.0.4. I tested Quake 3 Arena v1.17 on one clean partition and Unreal Tournament
v4.25a on another. Both games were allocated a minimum of 100 MB and a maximum of
150 MB of RAM. All of the tests were done with clean config files, where the resolution
and bit depth were manually changed from within the program. All of the config setups
were done under the "Normal" settings, and with Unreal Tournament, all
settings were on "High," with RAVE acceleration as the default. I manually
rebooted the machine after every five or so tests to clear out any bugs or memory
glitches. There are a few personal points that I would like to address before I continue.
First, we at IGM believe that any gameplay under 30 FPS, and any resolution below
640x480 is virtually unplayable, horrible, and useless. There’s not much sense in
playing a game if you can’t enjoy it visually because it’s jerky or choppy. The results
that we came up with for the "IGM Config" and "Loki Config" are
our own special touch to the testing procedure. The Loki Config script is recognized
in the Quake 3 community as the supposedly fastest config script that doesn’t sacrifice
gameplay. The IGM Config is an improvement upon the Loki Config that adds additional
FPS. Both the Loki and IGM Configs were only performed under 640x480, 16 Bit resolutions
as to preserve the nature of the high FPS. We understand that not everyone has the
fastest computer on the market, but once again, these results are meant to be relative
to your current machine.

As you can see above, the Radeon posts some impressive numbers, with the biggest
surprises being at higher resolutions. It seemed that the harder we pushed the Radeon,
the faster and more responsive it became. The Radeon’s Charisma Engine adds to the
mix with its ability to handle more clipping and lighting computations so that your
CPU doesn’t have to. This widens the information pipeline to the Radeon and takes
CPU load off of your computer. Unreal Tournament, we posted the results in addition
to the Quake 3 results knowing that the FPS would register lower due to the fact
that you’re comparing apples to oranges. In Quake, despite
the lower increase of FPS on the lower resolutions, at 86.4-FPS being our average
high, using the Radeon, we could achieve the same FPS with greatly increased viewing
detail at higher resolutions. What this means is that under our current IGM Config,
we saw no lighting effects, no textures, and an overall "blocky" feel to
the world around us. With the Radeon, we were able to turn up the lighting, textures,
geometric and texture details with only a minimum hit to our FPS. As we mentioned
before, any FPS above 60 is a luxury, and if you enjoy playing the game, why not
have it look good too. In addition, the character models looked the best we have
ever seen given the new "skinning" offers better character modeling. The
Pixel Tapestry Engine aids in the rendering of 3D textures and texture maps so that
you won’t lose any framerate, even in high action sequences. Below are some examples
of the way we were used to playing, to the way we’re playing now. Needless to say,
we’re never going back to the old, "blocky" regime.
In conclusion, we have to say that the ATI Radeon Mac Edition AGP video card is the
fastest video card out for the current G4 line. Its unparalleled 3D acceleration
along with its quick 2D performance make it an easy choice on a build-to-order G4.
Any hard core gamer will tell you the advantage of having higher FPS. It’s safe to
say that its the difference between blowing someone up, and being blown up. With
the Radeon, you don’t have to worry about slowing yourself down if you want to run
at higher resolutions. You purchased the newest G4, or you have a blazingly fast
upgrade, and you have more RAM in your computer than you know what to do with, so
why cheap out on the video card. The Radeon is the all-in-one card that offers DVD
and QuickTime enhancements, along with superior 3D acceleration that blows away all
of the competition.
