We know you've been waiting for this, haven't you?  Of course you have.  Since the launch of the Matrox G450, we don't know of any hard core PC Hardware Enthusiast that hasn't been waiting for Matrox to step back up to the plate, with a new high end 3D Gaming Graphics card.  It was then that Matrox Graphics made a conscious decision to step back from the ridiculously competitive 3D Graphics scene and watch as giants fell.  Perhaps their next generation 3D Gaming chip was not ready for prime time or perhaps they just didn't want to duke it out in the down and dirty retail space.  Either way, Matrox was content, at that point in time, with various OEM design wins for their mainstream "Dual Head" capable "Business Class" chip, where only casual gamers need apply.  There was no AA support for the G450 at the time and frame rates versus NVIDIA's current powerhouse, were none too exciting for the avid gamer.  Regardless, Matrox survived a severe industry down turn and weathered the storm, sustaining on their Business and Professional Graphics offerings.

On the other hand, at the time of the G400 and G400MAX, Matrox was fairly successful at evangelizing hardware assist for Environment Mapped Bump Mapping, an effect that is now a check list item for most all modern 3D Graphics cards.  It was this kind of innovation in image quality that Matrox garnered a strong following of loyal end users and enthusiasts.  There was always one simple constant with Matrox product back then, top notch 2D and 3D image quality.  Matrox always produced a sharp, stable display with vivid accurate color, no matter what the application. 

Well then, certainly it seems not much has changed for Matrox in their mission statement for this long awaited product launch.  However this time, the all new Matrox Parhelia 512 is targeted toward the high end 3D Graphics Enthusiast or Professional and as always, delivered in Matrox "High Fidelity". 

Let's take a look!

Processing power and the memory bandwidth to support it:

As you can see, this isn't your Dad's old G200, now is it kiddies?  Talk about having a wrap sheet a mile long!  There is more to know about this new graphics power plant from Matrox, than anyone ever imagined, when rumors started circulating a few weeks ago.  We'll try and break things down for you piece by piece, in the following pages.  However, remember two very important aspects of this new technology from Matrox.  First, this is the world's first 512 Bit Graphics Processor.  Second, this is also the worlds first implementation of a 256 bit DDR Memory Bus on a Graphics Processor.  Drop in some high speed 650MHz DDR DRAM and you are looking at a staggering 20GB/sec of memory bandwidth.

There are also a few more very unique attributes of the Parhelia 512, namely its integrated 10 Bit 400MHz RAMDACs and the fact that the GPU is AGP 8X compatible.  AGP 8X is obviously the next generation AGP graphics interface, with 2.1GB/sec of bandwidth, more than double that of AGP 4X.  However, the Parhelia 512 only supports up to AGP4X levels in terms of throughput.  It will however, still function in an AGP8X slot, when those are available from motherboard vendors.  What are more impressive perhaps, are the very high quality Color Palette DACs running at 400MHz, with full 10 bit resolution.  Again, these are hardware firsts for graphics technology.  Finally, we'll put the size of this chip into perspective for you. A Pentium 4 Northwood CPU has about 57 million transistors in its die.  The Matrox Parhelia has 80 million transistors.  So, you see now what we mean by "Big and Bad".  Now we'll show you how "Pretty" Matrox is trying to get with the Parhelia 512.
