Fill rate is a commonly used quantifier for computer graphics cards. It is measured in one of two quantities, either pixel
s/sec or texel
s/sec. According to Tom's Hardware
, a texel is equal to 480 pixels, and is a term invented
to sell Voodoo graphics cards
Fill rate becomes useful because graphics cards vary greatly in their rendering power, the most important difference being the number of rendering pipelines. A card with two rendering pipelines clocked at 200 MHz will have a fill rate almost exactly identical to a card with four rendering pipelines clocked at 100 MHz.
Most cards available today have fill rates in the 100s of Mtexels. The Geforce2 GTS claims a maximum fill rate of 1.6 GTexels, though the actual throughput is much lower, due to slow DRAM.
