Happy Birthday ATI! ATI has recently celebrated their 20th birthday as a company. Many companies have come and gone since ATI made their first video chip. In fact out of the 20+ companies that once made video card chipsets only two basically remain, NVIDIA and ATI. Other companies like XGI, VIA and Matrox don't make many chipsets, taking up less than 1% of the total market.
Last year ATI introduced the X800XT PE series to some great success. In fact, during most of the year, ATI had problems supplying as many cards and chips as there was demand for. Their main competition, NVIDIA also had supply-chain issues. Most of the year was taken up by NVIDIA and ATI selling every chip they could make. December of last year, ATI introduced their Spring refresh of the X800XT series, the X850XT PE.
