Elite Bastards posted a review on the Foxconn GeForce 8600 GTS video card

The most notable change here is in the number of 'Stream Processors' (what you would previously have termed 'Shader Units') available within the architecture - Compared to 128 Stream Processors in NVIDIA's flagship GeForce 8800 GTX part, G84 features just 32 processors, giving it (in its simplest terms, and of course things never are that simple with GPUs) a quarter of the fragment, vertex or geometry shading capabilities of its big brother. However, to offset this slashing in the number of Stream Processors, NVIDIA have made changes to the texturing capabilities of G84 - While each texturing unit in G80 can calculate just four texture addresses and eight filtering operations per clock, an equivalent unit in G84 can calculate twice as many addresses, leaving it capable of processing eight texture addresses and eight filtering operations per clock.
