QUESTIONS,
QUESTIONS, QUESTIONS...
1. Is the GeForce3
graphics card significantly faster than the
GeForce2 MX and Radeon?
2. Is the GeForce3 worth the $250 it costs to add
it as a build-to-order option?
3. Is it worth the $499 Apple charges for the kit
to upgrade existing G4 Power Macs with 4X AGP
slots?
4. Will the version 2.1 nVidia drivers make the
GeForce2 MX run faster? (Don't get excited.
Apple hasn't posted the 2.1 drivers... yet. They
come with the GeForce3 kit.)
5. Which 4X AGP system benefits most from the
speed of the GeForce3, the Dual G4/533 or the
G4/733?
I figure all you
bleeding edge G4 owners will be playing Quake 3
Arena in 1280 x 1024 resolution with textures and
geometric detail set to maximum to show off your
new 17" LCD Studio Display or 22" Cinema Display.
So this graph's for you.
The other boards
are gasping for breath while the GeForce3 just
cranks along.
I know many of
you don't care about high quality textures and high
resolution. You want to crank out lotza frames per
second. Here's what I call "minimum decent
quality." As you can see below, the GeForce3's
advantage shrinks in that mode.
This chart is
typical of what I observed with 2D applications. No
dominance by the GeForce3. It was faster than the
others but only slightly.
PERFORMANCE
ANALYSIS
If you run 3D
OpenGL applications like Quake 3 Arena in high
resolution, high texture, high detail mode, the
GeForce3's memory bandwidth and fillrate advantages
will clearly show. Having 64MB of DDR memory
doesn't hurt either. It's a tempting upgrade for
speed freaks like me.
However, if you
are running 3D applications at low resolution or 2D
applications like Final Cut Pro or Photoshop or MS
Office, you will NOT see significant improvements
in speed with the GeForce3.
The 2.1 version
of the nVidia drivers come with the GeForce3
upgrade kit. I thought, "Hmmm. I wonder if they
will speed up the GeForce2 MX." That's why the
charts above include results for the GeForce2 MX
with both versions. As you can see, they won't make
a GeForce3 out of a GeForce2. They are not
available on Apple's Tech Support section yet but I
expect they will be either posted there or included
in the next Mac OS 9.x revision. (I noticed the new
iBook had version 2.0 of the nVidia
drivers.)
A purchase of the
GeForce3 is an investment in the future of
Macintosh. It's packed
with potential
but the current Mac hardware, OS and applications
barely scratch the surface. For example, did you
know it can do High Resolution Anti-Aliasing? That
should be useful for applications like Maya and
LightWave.
As soon as Id
Software releases the "official" OS X version of
Quake 3 Arena, I will post those results with the
GeForce3 and other cards. Ditto for the AltiVec and
Multi-Processor aware version for Mac OS 9.1. Those
releases should add some excitement since Graeme
Devine, the software designer and project manager
of Q3A, has taken the GeForce3 into account when
working on the code.
Although Apple's
site states that it requires a Power Mac with a 4X
AGP slot, some web sites have reported success
using the GeForce3 with 2X AGP slotted Mac. But
don't expect it to perform near as well as on 4X
AGP machines.
If you are buying
a new, high end Power Mac, I think the $250 for the
optional GeForce3 is money well spent. If you are
buying it as an after market addon, it will cost
you twice that much. In that case, you might try
selling your old graphics card to help recover your
upgrade cost.
If you have any
other model of Power Mac with 2X AGP, 33MHz PCI or
66MHz PCI graphics card slot, the ATI
Radeon is
your best option for increased graphics speed. It's
a "BEST BUY" when you consider it costs as little
as $199 from retail sources like Outpost.com.

TEST
HARDWARE
Test machines included Apple's
Dual G4/533 Power Mac and "solo" G4/733 Power Mac.
They were configured with 512M of PC-133 memory and
were running Mac OS 9.1.
Graphics cards
tested included:
nVidia GeForce3
(2.1 drivers)
nVidia GeForce2
MX (1.11
and 2.1 drivers)
ATI
Radeon
Mac Edition AGP (latest drivers included with Mac
OS 9.1 including Radeon 3D Accelerator
6.2.3)
TEST
SOFTWARE
Quake
3 Arena 1.27h BETA
I tested at 1280x1024 "Maximum" (OpenGL, 32 bit
Color Depth, Lighting Map, Maximum Geometric
Detail, Maximum Texture Detail, 32 bit Texture
Quality, Trilinear Texture Filter)
I also posted a run at 800x600 "Normal" (OpenGL, 32
bit Color Depth, Lighting Map, Medium Geometric
Detail, Medium Texture Detail, 32 bit Texture
Quality, Bilinear Texture Filter)
TEST METHOD: When the main screen appears, I press
"~" and enter "timedemo 1" (return). Then enter
"demo demo127" (return). When the demo sequence
finishes and returns to the main screen, I press
"~" once more to get the frames per second readout.

document. Then time how many seconds to scroll from
top to bottom of the file.
