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.
