After making the Voodoo4 M4800, which works quite well, I asked myself a question. What would be better than a laptop equipped with one VSA-100? Well, a laptop equipped with two VSA-100, of course.
17" MXM 3.0/3.1 laptops usually support MXM type B, which is 3.5cm longer than the MXM type A usually found in 15" MXM 3.0/3.1 laptops. Surely the extra space will allow for an SLI setup.
Well, here it is:
It has all the features that the V4 M4800 has (selectable framebuffer size, VCORE control, temperature monitoring, backlight control etc), and has a higher performance PCIe to PCI bridge. The PCI clock can be adjusted from software (from a control panel similar to the V4 M4800 one), and there is a performance gain when running a dual VSA-100 card at 90MHz compared to 66MHz. It also has a 4x PCIe interface, so the extra bandwidth needed is not an issue.
Since the MXM standard was not designed with dual GPUs in mind, this card will require a custom heatspreader and heatpipes, possibly even a custom fin stack for whatever laptop it is installed in. This makes the card very impractical.
I should have the PCBs in a week or two.
