Once rumoured to see the light of the day in the first quarter of the year to coincisde with the launch of Microsoft Windows Vista, chipsets with built-in DirectX 10-supporting Mirage 4 graphics core from Silicon Integrated Systems Corp. are now slated to be unveiled only in the Q3 2007 or even later. The first core-logic from SiS to support DirectX 10 and high definition video acceleration – the SiS 673 – is projected to be commercially available in the third quarter and support various processors from Intel Corp. with up to 1066MHz processor system bus (PSB). The chip will also feature dual-channel DDR2 (up to PC2-6400, 800MHz) and DDR3 memory (up to PC3-8500, 1066MHz), according to a news-story by HKEPC web-site. In addition, there will be SiS 673 FX targeting high-end of the market with support for 1333MHz PSB and dual-channel DDR2 (up to PC2-8500, 1066MHz) and DDR3 (up to PC3-10600, 1333MHz) memory, but it is unclear when the chipset is set to be available.
The unofficial information also claims that SiS plans to release SiS 772 core-logic for processors by Advanced Micro Devices, which will also feature Mirage 4 graphics with DirectX 10 capabilities and acceleration of MPEG2, H.264, VC-1 and WMV9 video codecs. The core-logic will support HyperTransport 3 with 5.20 gigatransfers per second speed.
