Frankly speaking, this card, the first one from the Voodoo family, has greatly upset us. For us the Voodoo namehas always meant something extremely cooland now it's not only the best one but even not a fifty-fifty card!

Table of contents:

• Conclusions
  

Inthe beginning of this year a new graphics cards family from 3dfx Interactive was announced. You haven'tmisheard: it was graphics cards that they meant and not chipsets, as we could suppose. 3dfx became theonly manufacturer of graphics cards based on its own chips after having merged with STB Systems.

The new chipsets were called Voodoo3 and got divided into 3 types: Voodoo3 2000, Voodoo3 3000and Voodoo3 3500 with the corresponding core and memory frequencies equal to 143, 166 and 183MHz. Rememberthe time when Riva TNT and Banshee were driving everyone crazy, and Voodoo2 was still pretty popular. Thenpeople, who were so much used to frequencies varying somewhere between 90 and 110MHz, could hardly imaginethat one day the frequency would reach 183MHz. But nevertheless life continued its usual course andall we could do was just to have patience and wait for this wonder to come to Russia.

However, it was then that we started doubting the true practical value of this masterpiece. Of course,the speed was supposed to be rather high, especially in the latest models, but all the rest seemed toremain on almost the same level. For example, Voodoo3 image quality was expected to be very similar tothat of Banshee despite 3dfx's attempts to promote the 22-bit rendering, which was supposed to give aperfect 16-bit image.

And finally we also managed to get Voodoo3 2000 for a couple of benchmarks, so if you have anyquestions, please, address them to us and we'll try to satisfy your curiosity. But before we start we'dlike to offer you a complete set of Voodoo3 2000 specs:

It can be easily noticed that the main features distinguishing Voodoo3 from Banshee are higher coreand memory frequencies, 300MHz RAMDAC and multitexturing. Closing our eyes to the forthcoming benchmarkswe are tempted to call it Banshee2. Why so? Well, it's very simple. About a year ago Voodoo2 chipsetaroused public excitement and enthusiasm in the market of gaming 3D-accelerators, which was a greatleap forward compared to Voodoo1 (Voodoo Graphics). That's why for most people the next number in thename of this device means revolutionary performance improvement, while in fact Voodoo3 is none other thanan overclocked Voodoo2 with Banshee2D. Of course, 3dfx was aware of this psychological phenomenon. Andin order to attract public attention this company called its new product Voodoo3 on purpose, whichactually was a very successful marketing move since 3dfx is no longer the only leader in 3D gaminggraphics market.

Nevertheless, people very rarely happen to remain absolutely indifferent to such novelties as Voodoo32000 for instance, especially taking into account its relatively low price. And as for us, we werelucky to get it for benchmarking.

So, let's pass over to the main point. 3dfx Voodoo3 2000 graphics card is an AGP board (PCI versionwill be also available) with 16MB 7ns-SDRAM.

The first thing that catches your eye is an extremely familiar board design, which looks very muchlike STB Velocity 4400. This observation makes us suspect that STB decided to save itself time andtrouble by leaving the same outlook for its new product. Besides the chipset itself and 8 memory modulesthe board is also equipped with a BIOS chip and its accompanying logic. There are also free spaces forchips and TV-out connectors (as to the announcements they will be only on 3000 and 3500 models). But whatmakes it almost impossible to distinguish between Voodoo3 2000 and STB Velocity 4400 is a black pinradiator, set onto the chipset.

Unfortunately, we can't say anything about the whole package set since we've got just an OEM-sample.

The testing system included the following components:

• Chaintech 6BTM mainboard;
• Intel Pentium II 450 & Intel Pentium III 450 CPU;
• 128Mb PC-100 SDRAM;
• Nokia 447Xav (17") monitor;
• Windows 98.

Besides we provided the graphics card with an additional cooler, which sent the air stream directly tothe graphics board radiator.

Well, enough for that. You have probably got the general idea of this device, so we can start lookingat Voodoo3 2000 at work. First of all, a few words about installation. The drivers are supplied on theenclosed CD-disk. They are all packed into one single EXE-file that is why at first a Standard VGA adaptershould be installed. After unpacking and installing the drivers, in the display properties panel appearedseveral additional pages with graphics card controls. The contents of these additional pages is similarto the well known settings of Voodoo2 or Banshee that's why we won't dwell here (there is Vsync closingoption, triple buffer and dithering). Besides, there is also a mark, which serves to balance the ratiobetween quality and quantity and which may take extreme values (on/off), and avoid smoothing the picture(as most other graphics cards do).

According to the achieved results the value of this parameter influences neither image quality, norgraphics card working rate.

A certain pageprovides us with some graphics card statistics: e.g. its type, drivers revision, memory, etc.

Here you can actually see that we used the drivers version dated back to 20 March, 1999, and aminiGL-driver (OpenGL wrapper) - 1.47.

Undoubtedly, many of you paid attention to primarily chipset and memory frequencies displayed on thescreenshot: 174MHz (frankly speaking, it implies 175MHz). And many of you are definitely puzzled becauseall this seems absolutely impossible, especially when you know that the chipset is initially designed for143MHz. And the explanation is very simple: it is a special Voodoo3 overclocking program that is toblame - Voodoo3 Overclock Property Page (by Gary Peterson). It is installed separately and creates anotherpage in monitor settings list.

Herewe get the whole set of cool options. We may not only smoothly change Voodoo3 chip performance and memoryfrequency from 120MHz to 200MHz, but also disable Vsync (monitor refresh rate synchronization with RAMDAC).After changing the frequency, the PC should be restarted. By simply trying all the suitable combinationswe managed to find the maximal frequency - 175MHz, when the card shows a rather stable performance. Iteven exceeds the nominal frequency of Voodoo3 3000 (166MHz), which is very pleasing for all overclockingfans.

The next point. Any benchmark - even if all the values are beautifully arranged in colorful charts -is half the battle. These numbers may be of any use only to a specialist, and the common user alwaysneeds a comparative analysis with some other products, which have already been tested and studied insideout. And the present case isn't an exception. Stating that Voodoo3 is slower or faster is not enough.To make it more illustrative and hence more persuasive it should be given in comparison with the othercards. That is why we decided to take the already known benchmark results of the popular graphics cardsbased on the following chipsets: Nvidia Riva TNT (Creative Graphics Blaster Riva TNT), ATI Rage128 (ATIRage Fury), and Voodoo2 SLI (Quantum3D Obsidian2 X-24). The performance of all these graphics cardsapproximates to that of the most novelties and their price is close to that of Voodoo3 (with the onlyexception of Voodoo2 SLI, which is still quite expensive).

The first issue we'd like to consider deals with Voodoo3 2000 performance rate and quality in2D-graphics. To check it we ran a popular WinBench99 and obtained the following results:

To our great disappointment we have to admit that the only noticeable improvement was a slightRAMDAC increase. As for the rest - nothing had changed there despite 3dfx's promise to improve2D-graphics, which hasn't yet been put into practice. The results can be compared to those of Banshee,Voodoo3 2000 predecessor.

However, we cannot deny that 2D-graphics quality has risen. May not so great as we wished, but with1280x1024 resolution my eyes were quite comfortable, everything was clear-cut and distinct, and thespeed visually seemed really cool. At a greater resolution 1600x1200 the picture got a bit vaguercontours, however, we should bear in mind that some monitors (mine, for example) do not nominally supportthe resolution over 1280x1024, and all the objects on the screen were too small.

In this respect a conclusion inevitably comes to mind: there are some purely visual improvements inquality but they are relatively insignificant, and Voodoo3 speed values were somewhere on Banshee level,which is actually enough for a gaming graphics card.

We are swiftly moving forward and now we finally approach the sacred 3D-kingdom. :) Let's start withquantitative values characterizing the board's performance speed. To look at it we utilized a couple oftools:

• 3Dmark99 MAX from FutureMark (DirectX)
• Quake2 from id Software (OpenGL)
• Incoming from Rage Software (DirectX)

We considered Voodoo3 2000 working at two different frequency settings - at its nominal frequency143MHz and at the overclocked frequency 175MHz.

The results obtained are given below:

We would like to point out that all the values presented above were obtained with 16-bit color depthsince it is the only color depth Voodoo3 supports in 3D.

Then comes the Voodoo3 2000 performance scalability diagram:

Let's discuss these results in detail. The first thing, which is worth mentioning, is the dataobtained with Pentium III CPU in 3DMark 99 MAX. The video chipset was overclocked to 175MHz and the dataachieved at this frequency are listed in the table below:

The speed proved to fantastically increase as soon as it came to SSE support. Unfortunately, now wecan enjoy it only in benchmarks like 3DMark99 MAX and various demo-utilities because the market cannot yetboast any SSE supporting games.

Then. The first and the most important conclusion sounds very discouraging: we have come a cropper!Yes, that's the bare truth! Graphics accelerators become so cool and fast that the CPUs are simply unableto keep pace with them. Have a look at the charts for 640x480 and 800x600! Super-high frequency Voodoo3showed practically the same result as the graphics cards of the previous generation did. And only at1024x768 the difference will become significant. What does this all mean? And it actually means that nomatter what you will acquire a Voodoo2 SLI, a Riva TNT or a Voodoo3, you will also need a big monitor, sothat you could enjoy all the beauty and coolness of 3D-picture at higher resolutions. A super-acceleratorcombined with a low resolution (640x480, for instance) will be just a waste of money and absolutely nosatisfaction. In other words, while most cool processors, which provide a significantly higher graphicscard performance, are still too expensive, purchasing a new accelerator will make sense only if you havea 17" monitor (or even bigger).

However, it should be noted that OpenGL shows a bit different picture. Voodoo3 2000 speed gainappears significant at 640x480 as well, which is clearly displayed in Quake2.

And in addition the scalability diagram above beautifully demonstrates the limitation imposed by CPUfrequency on Voodoo3 speed increasing.

Nevertheless, we simply can't disregard the Voodoo3 2000 extremely high speed especially with theprocessor overclocked up to 175MHz.

To conclude with we'd like to share the following idea. If 3D-image quality is supposed to be on thesame level for all the chipsets, then buying a Voodoo3 2000 (not to mention the graphics cards withcooler performance) will sound reasonable only with at least 400MHz processor frequency.

Uh! Well, it looks as if we are through with the performance rate, and now it's high time we tackledthe quality. We can competently announce that the quality is exactly the same as that by Bansheeincluding all drawbacks, especially in terms of alpha-blending. Below you can see the outcome of three3DMark 99 MAX tests showing different ways of alpha-blending (Riva TNT is also given for a bettercomparison):

1. Adaptive alpha-blending

2. Multiplicative alpha-blending

   Reference image

   
   
3. Combined alpha-blending
   

   3dfx Voodoo3 2000	nVidia Riva TNT
   Reference image

These figures clearly show that banding is typical of Voodoo3 in every test and is totally absent byRivaTNT.

Then we have to mention a great performance impairing as it comes to larger textures since Voodoo3doesn't have any corresponding support:

Besides, the image quality in one of 3DMark 99 MAX gaming episodes seems worth your attention:

Reference image

The screenshots of Voodoo3 performance nicely show that the latticed floor has a washed out grainoutlook. Actually the blurring has become a permanent characteristics of 3dfx graphics cards because theyhave definitely gone too far trying to get rid of image discreteness (pixellization).

And finally, take a look at a couple of screenshots of Voodoo3 OpenGL performance (Riva TNT data isalso given for a better comparison). This is a game called Kingpin:

3dfx Voodoo3 2000		nVidia Riva TNT

It's really hard to find any grave differences but as for us, a warmer and livelier Riva TNT picturecheers the cockles of our heart.

So, the benchmarks prove that those who prefer Voodo2 or Banshee will be satisfied with Voodoo3 aswell. However, there is one great drawback. You have probably noticed that we omitted the performance ofVoodoo3 in Glide-games. Actually for a very commonplace reason: the terrific Unreal (the initial purelyGlide-version as well as 2.20 version), the brilliant motor races Need For Speed III simply can't getstarted in Glide. 3dfx couldn't probably think of anything better but change Glide specification rightbefore the launching of Voodoo3. As a result the drivers contain a new API-version, which turns out notquite compatible with the older one. And this in its turn means that we can do nothing but wait and waitfor the new Glide-games patches to come out. Epic Megagames promises to improve the situation only witha new patch 2.24, Electronic Arts is still keeping silence. The situation strikes as very similar toBanshee case, doesn't it? To be fair we should say that NFSIII and Unreal 2.20 can be run in Direct3Dand perform beautifully (it refers especially to Unreal, which achieved 51fps at 1024x768). However,Unreal D3D version is rich in inaccurate scene details imaging that's why a new patch will be stronglyrecommended (though the following remark doesn't make much sense if you haven't seen Unreal Glide).

Before drawing the final conclusions we would like to say that despite 0.25 micron technology thegraphics card gets very warm while working (especially while overclocking), that is why we advise youto acquire appropriate coolers, aka chip coolers, which are already available in retail.

Conclusions

Taking into account Voodoo3 2000 relatively low price (it's cheaper than ATI Rage Fury, for example)we would recommend the following graphics card for powerful CPUs owners. It will be very up to dateand will serve you faithfully before the market is overwhelmed by new games with 32-bit Z-buffer support,with the evident difference between 32-bit and 16-bit color, and with textures exceeding 256x256 andmaking use of AGP potential. Long before we got Voodoo3 for benchmarks it was already clear that thisgraphics card as all the 3dfx previous chipsets can't be fully with AGP. This fact was proved by 3DMark 99MAX for larger textures, which simply exhausted Voodoo3.

If you are put into a dilemma and can't decide between Voodoo2 SLI and Voodoo3 2000 we would tell youwith all certainty: take Voodoo3 2000! It is almost twice as cheap as Voodoo2 SLI however the performanceis on the same level (and even higher if overclocked). For those who already have a Voodoo2 and whowant to buy a second one to make a SLI we would advise to sell it together with 2D-card as soon aspossible and to get a Voodoo3 2000. As a result you will get a considerably good 2D and an excellent3D-graphics.

And as for Riva TNT-, or Rage128-based graphics cards owners it's hard to find any suitablerecommendation. They'd better not bargain one trouble for another and wait for Riva TNT2 or Matrox G400to come out. Considering that it is about to appear pretty soon.
