NVIDIA cited a study from Mercury Research about Q4 2004, claiming that they hold 67% of the DirectX 9.0 performance market and 53% of the overall DirectX 9.0 market. A quarter earlier the company hold respectively 64% and 51% of the high-end and mainstream market.
While the mainstream DirectX 9.0 market indicates relatively slow expansion of NVIDIA, the same cannot be said about the high-end DX9 shipments. Mercury’s current estimates on DX9 and DX9c accelerators differentiate value and performance by transistor count, with devices at and about 100 million transistors being considered high end. Since enthusiasts and media typically consider pricing and performance as two main measurements of a products’ market positioning, Mercury’s estimations may be regarded as not precisely reflecting reality.
