VisionTek GeForce3 Video Card Review By: Joe

The Benchmarks -
|
|
|
Lets start with Windows 98 SE Marks -
|
|
|
In the Legend at the bottom of the graphs its formatted as such:
"GF3 12.00 230 500" Means = GeForce 3 Video card, V12.00 Dets, 230Mhz Core 500Mhz RamDDR
Anything that reads "GF3 Enhanced" means it was using GL Marks GF3 Enhanced Benchmark.
All 3DMark 2001 benchmarks were run with the Default 1024x768x32 benchmarks with the Nature Demo's disabled. For 3DMark 2000 testing they were run at the
default 1024x768x16 bench.

Under Windows 98 SE, you can see it scales rather nicely. With the GF2 Ultra at stock speed being the bottom benchmark for all the other
tests. At 4201 that's no shabby score.
I am very interested in any advantages or disadvantages the different driver versions made in the performance. From Win98 SE you can see there
is little if any difference in speed between them on the GF3 or the Ultra.

The OverClocking speed difference is interesting as we can see clearly the efficiency of the GF3's core compared to the more brute force setup of the GF2
Ultra. The Delta of difference between a Non OC'd and a OC'd GF2 Core was around 430 with the core OC'd by 50Mhz, and the Ram OC'd by 62Mhz.
The GF3 on the other hand had a 530 difference with the Core OC'd 30Mhz and the ram OC'd 40Mhz. Those are some nice numbers. Since I needed
something that was stable across the board I picked the highest reliable speed for all the tests which turned out to be 300/520 for the Ultra, and 230/500 for the GF3.
I am able to take both these cards well past those points but stability becomes a concern.

This was a test that many people will see as invalid as it doesn't use the GF3's core to its peak potential. I see it as very valid as most
people do NOT use games that can use the GF3 core yet anyway.
In here you can see some breaking from the nice scaling we had on the 2001 test. In this one its pretty clear that Dx7 API apps can
turn the tables on the big bad GF3.
At this point raw MHZ seem to mean more then the technology in the core. But still Clocked almost 70Mhz slower at the core, and 20Mhz slower at the ram it still comes within 60Marks of the GF2 Ultra.

This is quite a change from he 2001 Benchmarks as now the GF3 v12.00 is the SLOWEST card in the race.. by a BIG margin, almost 100 Marks. its also amazing
to see the difference between v11.01 and v12.00 drivers is over 200 marks to the GF3. But to the GF2 Ultra is the opposite effect! its a 100 mark gain to go to v12.00 Drivers.

The GLMark was a great test to run as many games and apps use Open GL more then D3D currently. This also is an area the GF3 just KILLED the
competition. And also exposed some nice speed differences.
In the tests you can see the GF3 using V11.01 at stock speed is second at the top. But using the v12.00 driver it fourth from the bottom. In this test you can see that the v12 drivers suck all the way around on OpenGL performance for the GF2 and GF3. You can see I did OC the GF3 a bit more as it seemed to remain stable at 520Mhz for the Ram in this test.
The GF3 Enhanced tests using the Pixel shaders and such, did take a bit of a performance impact on that was not bad, but at the same time made the
benchmark look just amazing.

The performance at 79.7FPS is just amazing, that's over a 50% in come cases a 100% speed improvement over the GF2 Ultra!
|
|
|
|
Now Onto the W2K Benchmarks-
|
|
|
|
The W2K Benchmarks were the first I ran and forgot about the Pixel Shader Nature Demo issue when comparing the cards. So I ran an extra one to show
the drop in 3DMark scores with the Pixel Shader Tests Disabled.
Once again in W2K you can see the nice scaling between the cards with the drivers playing almost no roll in performance differences.
What was really amazing is that in W2K 3DMark was giving higher scores then Windows 98 SE!!! THATS A SHOCK. As its always been known that
W2K's HAL layer was a major slowdown for many 3D apps. Seems Nv's drivers are overcoming those issues.

The reason the Ultra was at 515 mem speed for one test is I just could not get it to complete the bench at 520.
It was a very weird thing as I just ran it through some benchmarks before at 535 and it worked but then at 520 it would nt. 6115 in Windows 2000, All I have to say is DAMN.
|
|
|
|
I was just in amazement in the performance difference in this test.
You can see clearly that the v12.00 Dets still suck, but wait.. now a GF3 with a v12.00 scored the highest on the entire benchmark!!! All I have to say is this is one wacky driver under W2K, in one test is bites and in another it rules. But then again we are talking a difference of 20 - 30 Marks.

I didn't use GLMark much in the W2K test as I was more interested in seeing the Win98 Tests but I did run them all at 11.01 as it seemed to be the
fastest driver for Open GL that Nv has out. You can see there is a totally difference of 4Fps in this chart, a MUCH different story from the Win 98 test where we saw the differences of 30 - 40Fps.

More Performance Benchmarks-

This is a nice representation of what kind
of performance degradation you can expect from using AA in games. You will be able to see the difference in the next part of this review of what the different AA levels look like.
The main thing is how close the Quincunx AA is to the 2x AA.
Quincunx is a new method for doing AA that gives 4x AA at 2x Performance hit. You can see its a bit more of a hit, but really not much.

I wanted to see how fast I can run this card. So I ran some strictly GF3 speed tests.
I got the card running stable at 240/535. From the marks I got of 7028 and 6234 I have beat by over 400 the highest marks recorded on MadOnions site for those tests as of 4/17/01.
Its clear that at the 640x480 res the CPU is the limiting factor as the card is being very under worked. At 1280x1024 I was just amazed that
it still performed so well!! I ran the base speed Vs the OC speed for the 640x480 and the 1280x1024.
