On a more serious note - I cant help feel that its unfair to include matrox in these charts because the commercial market isnt exactly their main focus. Matrox is more of an industrial market thing.
The above figures also include
math co-processors (Tesla, FirePro S series, and whatever miniscule number of Xeon Phi's are sold),
medical imaging (mainly Quadro), non-embedded digital signage, and a host of other industrial applications. Matrox's product line is no different from any
AMD or Nvidia
visualization product. The only point to note is that Matrox's sales figures are so low that there would be a considerable margin of rounding to achieve a one decimal place final percentage.
