Although presentations that are internal to companies never make it to the public scene, some of those presentations are interesting, to say the least. Computer hardware manufacturers spread around an area as saturated as Taiwan, China, Malaysia, etc., get so involved into aggressive competition that in more occassions than one they get carried away. Internal presentations are the ones manufacturers such as ASUSTek, MSI and Gigabyte share with their potential customers in channel vendors, OEMs, and the likes. One such presentation by MSI, a particular slide of which, has become an example of how far competition has taken the manufacturers.
MSI, in one of its internal presentations regarding its G45M Digital motherboards, accuses Gigabyte of misleading its consumers by selling motherboards with "crippled VGA slots". Quite simply put, the VGA slot, in this case, PCI-Express x16 slots most commonly used to install graphics cards are "crippled" by Gigabyte, by reducing its number of PCI-Express lanes. The affected Gigabyte motherboards, according to MSI are EG45M-DS2H, EG43M-SH2H, and EG41MF-S2H. So while the slots are mechanically PCI-Express x16, they are electrically PCI-Express x4 (with a bandwidth reduction of 75%). MSI backs its claims with Gigabyte's own data published on its website.
Now comes the question of "Why?". The Intel G4x northbridge is capable of providing 16 lanes to a mechanical x16 PCI-Express slot, but it would also mean wiring the northbridge to the slot. With the way in which PCI-Express is built, the number of available lanes can be manipulated by simply not connecting the lanes to the device. In this case, not wiring all the lanes to the slot, when the northbridge is very much capable of providing the lanes. Furthermore, Gigabyte put up a "VGA compatibility list". Backed with credible evidence, MSI looks to capitalise on Gigabyte's design flaws in its own marketing campaign.
