nForce4
The vanilla version of the board will have no special features and will have the HyperTransport link limited to 800MHz on Socket 754 motherboads.
nForce4 Ultra
The Ultra version will contain all of the features of the vanilla version with the addition of:
- Hardware processing for the ActiveArmor to reduce CPU load
- No 800 MHz limit on HyperTransport
- 3Gb/s transfer speeds for SATA drives (SATA-II)
nForce4 SLI
The SLI version has all the features of the Ultra version in addition to SLI (Scalable Link Interface). This interface allows 2 video cards to be connected together to produce a single output. This nearly double framerates by splitting work between the two GPUs.
