Our friends over at
HKEPC posted some interesting information on the NVIDIA Quad SLI technology
through an interview with NVIDIA desktop chipset manager, George Myers.
Apparently, the SLI technology on the Gigabyte 3D1 and ASUS Extreme DUAL cards
is different from the Quad SLI technology. Each of the Dual 7800GTX 512 card is
specially made and has an additional chip onboard to control the data transfer
to both the GPUs for calculation. Quad SLI can be used on nForce 4 SLI x16 AMD
as well as Intel Edition. The reason why Quad SLI uses 1-3 2-4 MIO connection
method is to reduce the Northbridge and Southbridge HTT bandwidth usage as the
calculated data can be transferred from the Dual 7800GTX 512MB card on the
Northbridge through the MIO to the Dual 7800GTX 512MB card on the Southbridge.
