Inbe times November of final year, NVIDIA revealed their replacement tothe nForce five, the nForce 600 series. The commencing line-up admit3 results confirming Intel's Core 2 CPU, each proposed at a unlikesection of the market and each with a dissimilar cost point. The mostvaluable chipset in the series, the high-end 680i SLI supplied a hostof novel characteristics admitting dual X16 SLI defend with a 3rd X8PCI-E slot.
Following arrives the 650i SLI, which lacks lots of the 680i's fanciercharacteristics similar double x16 SLI defend, but constructs up forit with a importantly lower cost point. Eventually at the down finalis the 650i Ultra, which lacks SLI defend completely.While the 3boards in the series did a beneficial job of crossing the differentsections of the market, there was a substantial cost gap amongst the680i SLI and the 650i SLI chipsets. becoming from a 650i SLI to a680i SLI generally meant a cost rise of approximately $100.
ASUS detect a result to the trouble by bringing in a board that extendedmost of the same characteristics of the 680i SLI at a lower cost,corresponding right into the cost gap.They did this by producingtheir own hybrid chipset in practice with NVIDIA, dubbed the "NVIDIAdouble X16 SLI".To accept birth to the NVIDIA double X16 SLI,ASUS mated a nPower 650i SLI northbridge with a AMD version nForce570 SLI MCP southbridge.
The 650i SLI northbridge supplies defend for 1 of 2 X16 PCI-E slots whilecovering communications with the CPU and storage. The 570 SLI MCPsouthbridge supplies the bandwidth for the 2nd X16 PCI-E slot, aswell as a 3rd full-sized PCI-E slot with an X8 electricalassociation, in increase to dealing the board's memorycharacteristics.
