The GeForce 8 Series, a computer graphics processing unit, is the eighth generation of NVIDIA's GeForce line. The third major GPU architecture developed at NVIDIA, the GeForce 8 represents the company's first unified shader architecture. It competed primarily against ATI's Radeon HD 2000-series cards.There has been, at times, controversy over the naming of GeForce 8 series chips, including due to previous-generation chips being repackaged with minor changes (or possibly none at all) with the new names implying they are derived from the newly-introduced GPU chip design featured by the flagship products.
