Despite refreshing its Intel chipsets relatively often, Nvidia seems to have left out the AMD market these past few months. The graphics company's latest mid-range nForce chipset for AMD chips is the nForce 570 SLI, which came out in 2006 and doesn't support some of the features of new quad-core Phenom processors, such as HyperTransport 3.0.
However, judging by a report by OC Workbench, that's all about to change. The site has gotten hold of pictures and specifications for an ASRock motherboard based on a yet-unannounced nForce 750a SLI chipset. As its name suggests, the chipset looks to be the AMD version of the nForce 750i SLI, and OC Workbench says it has full support for Socket AM2+ processors with HyperTransport 3.0. Naturally, the chipset also supports SLI dual-GPU configurations with one PCI Express x16 slot sporting a full 16 lanes of connectivity and the other featuring only eight lanes.
Looking at the ASRock motherboard, which bears a K10N750SLI-WiFi model name, we can spot seven 300MB/s Serial ATA ports (including one external port), three PCI slots, one PCIe x1 slot, a pair of physical x16 slots, and both FireWire and Gigabit Ethernet connectivity. True to its model name, the mobo also has integrated Wi-Fi support with an external antenna.
