Canopus has released another of its famous product. Will the PURE3D II beat all the rest of its competitors like the Total3D 128V? Anyway, this Voodoo 2 based card is one of my personal favorite. The card is quite well design using high quality PCB board.With 24 Silicon Magic 256k memory of 100MHz 25ns EDO DRAM code as F9808 SM81C256K16CJ-25 on both sides. Until now you might have noticed that the layout of the Voodoo2 based cards are about the same. But this $498 baby is no average performer, it is slightly faster than the Magic3D Plus. The package comes with the standard user manual, Installation CD and a game demos CD.


Installation of the card was easy. The PCB sits nicely in between my network card and my Total3D 128V. The plug and play installation of card and the software is a piece of cake. For all the experienced DIY people, you would surely like this card. Take a look at the card below :

The Good

Running it on my K6 300 Mhz processor makes it jumped about 80% over my Total 3D 128V card.The enhancement of picture quality and faster frame rates are very evident and noticeable when running this 12MB board.Canopus has also lived up to its name by using the very high quality 25 pieces of Silicon Magic 100MHz 25ns EDO DRAM

The Voodoo 2 card is currently the most powerful card in the consumer 3D arena.Heating problem is not too much of a problem since the fan is provided. But it's always advisable to leave a slot gap between others PCI periperhals. Quake II Mission Pack : The Reckoning is also the added bonus in the package. (But Quake II is required for this mission pack add-on).

Its ability to overclock to 100 Mhz is another plus points over its competitors. (Click on "Advance") This is made possible again by the fan cooler on board.  There is another interesting point to this board. There is a LED that lit up (green) when it is active. In this case, you know exactly whether your effects are "Voodoo2ed" or not. The green light could be observed through the composite video connector. After installation, there is also an additional Canopus Quick control dialog and a launch bar. For your information, The Fan Cool cost you S$ 35 @ Interactive Media, Sim Lim Square. (Wow! Expensive Fan!)

The Bad

There isn't any serious problems with this card. The fact that voodoo2 cards are highly dependent of CPU processors still holds with this card. The relatively heavier price tag is a good hindering factor to get this Voodoo2 card. The awkward position of the SLI connector is probably the only fault I can find on this PCB. This position will require the user to use a longer SLI cable (luckily provided) and thus contributing to the cramp in the casing.

The last bad point about this card is the fact that when you inserted this card into one of the PCI slots, you will not be able to inserted another card into the direct neighbour of it. (However, you can choose to squeeze it in.....but it is not recommended.)

SLI Test

We are fortunate to receive two cards from our sponsors. Thus, we are able to do a SLI test with the Total3D 128V. The results were rather disappointing but somehow anticipated.(High CPU Dependency). Anyway, here are the results

Quake 2 Timedemo2 / fps 36.9 36.7

It can be observed that the advantages of SLI is not fully harvested from even a K6 300 Mhz overclocked system. There is only a 0.5 fps increase from another Voodoo2 card. (Certainly not worth for two in my case.) The slight negligible decrease from the 640 x 480 framerates from the 1024 x 768 framerates show that the Voodoo2 Chips are actually waiting for the CPU. One can draw a conclusion here about SLI on my system : Due to the antense CPU dependency, the adding of another Voodoo2 card will not be efficient if you have a relatively weaker system. The recommendation here is that if you do not have at least a Intel Pentium II 300 or equivalent system, please invest in something else.

Overall,if you are looking for one of the best quality Voodoo2, this will be your best candidate.The overall 3D WinMark score are no more than 5% difference from others reference card based Voodoo2. If you have a Pentium II 300 and above and if you are going for a voodoo2 card, I would really recommend that you get this Canopus card. You won't regret you did.
