[edit] History
In December of 2003, XGI announced the Volari Duo, a graphics card with two GPUs. This was seen as part of a potentially successful attempt to become competitive with ATI Technologies and Nvidia Corporation, which are the two largest GPU manufacturers in the world.
A few months after the announced release of XGI graphics cards were found by enthusiasts and hardware reviewers to be less than competitive with ATi and Nvidia cards. Some of the many performance and visualization problems were blamed on underdeveloped drivers. Even so XGI cards received good reviews in the low priced/low performance video card market: XGI Volari V3 cards were judged by some reviewers to be competitive and even superior to equally priced video cards that were on the market, such as a Nvidia GeForce MX 4000 card. Many reviewers though were pessimistic of the possibility that XGI would competitive in the 3D graphic card market.
On March 6, 2006, ATI Technologies announced the acquisition of Shanghai-based MacroSynergy, a fabless chip designer and XGI Technology alliance company, as well as related personnel working out of XGI Technology's Santa Clara, California location.
On 2006-10-17, RealVision Inc. announced forming technology alliance with XGI Technology Inc. [1] On 2006-10-23, RealVision Inc. announced VREngine/XMD-Advanced series video cards[2], which uses the previously cancelled Volari 8300 (named Volari XG47), for use in medical imaging. Mass production would begin on 2007Q1.
