also responded in 2007 with two upcoming platforms, one in CeBIT codenamed V8, targeting workstation market and one in 2007 Beijing Intel Developer Forum (IDF), codenamed Skulltrail for enthusiasts, both with similar dual-processor configuration but with V8 lacking multi-graphics support. Reception Reviews of the platform have been largely unfavourable. Reviewers have noted that the platform requires significantly more power than a Core 2 Extreme QX6700 processor system, with performance being generally inferior. In some cases, performance was seen to be even lower than the dual-core FX-62, which has been blamed on higher memory latency introduced by the platform's use of Non-Uniform Memory Access. Availability The platform was launched in November 2006. Three new processors, the FX-70, FX-72 and FX-74 are released simultaneously with clock speeds of 2.6 GHz, 2.8 GHz and 3.0 GHz respectively. FX-76, clocked at speed of 3.2 GHz, was scheduled to be released in 2007, but was cancelled for the newer 65 nm microarchitecture Phenom FX processors replacing the 90 nm fabrication process line of Athlon 64 FX series processor. Chipsets Nvidia Nvidia has introduced a chipset for the platform, called "nForce 680a", provides 4 PCI-Express slots of x16-x8-x16-x8 configuration, and support up to 12 SATA 3.0 Gbit/s hard disks. ASUSteK will produce the first motherboard that will support two Socket F (dubbed as socket L1FX by Nvidia) processors each with its own dedicated memory banks, dubbed as "ASUS L1N64-SLI WS" (instead of the L1N64-SLI Deluxe that Nvidia announced), based on Nvidia nForce 680a chipset. Reports suggested that ASUStek is the sole motherboard manufacturer for the chipset and left other motherboard manufacturers out, some of which stated that they will produce motherboards based on Intel chipsets instead. There are also reports showing that the L1N64-SLI WS motherboard supports a pair of 2200 series CPU in the Opteron family without modifications to the motherboard, and the chipset was recognized as "nForce 570 SLI" chipset revision A1 instead of "nForce 680a" chipset. ATI Technologies/AMD In October 2006, sites leaked ATI chipset updates that ATI will also introduce a chipset connecting two AMD processors and four PCI-Express graphic cards, dubbed as "790FX chipset" (codenamed RD790), which provides PCI Express slots of x8-x8-x8-x8 configuration, and was available during the first half of 2007. In September and October 2007 news sites reported that AMD had dropped Quad Phenom from their road maps. Source also revealed that a revamped "580X" chipset, which is
