As to why all this bulk is necessary, let’s look at the specifications for a couple of industry firsts. The Parhelia is the first ever 512 bit GPU, and this, combined with the (also) brand new 256 bit DDR memory bus will combine to give this new Graphics processor excellent bandwidth. Built on an eight-layer PCB to accommodate the complexity of the required routes, Matrox is claiming 20GB/s, almost double the memory bandwidth of the current Geforce 4 Titanium.
This number is still up in the air as no specific GPU clock and memory timing information have been released yet. With the core running somewhere around 270-300 MHZ and the memory at 300-325MHZ DDR it would be right around 20BG/s; so consider these numbers as good ballpark figures. The Parhelia will have the capability of addressing up to 256MB of DDR RAM which is pretty astounding as well.
