今日好多站都引述咗AnandTech篇報導, 3GS牌面上用最新&... 恕刪
The meaning of fillrate, I searched from web.
usually refers to the number of pixels a video card
can render and write to video memory in a second
. In this case, fillrates are given in megapixels
per second or in gigapixels
per second (in the case of newer cards), and they are obtained by multiplying the number of raster operations (ROPs) by the clock frequency of the graphics processor unit (GPU
) of a video card
. However, there is no agreement on how to calculate and report fillrates. Other possible methods are: to multiply the number of texture units by the clock frequency, or to multiply the number of pixel pipelines by the clock frequency. 
The result of this multiplications correspond to a theoretical number. The actual fillrate depends on many other factors. In the past, the fillrate has been used as an indicator of performance by video card manufacturers such as ATI
, however, the importance of the fillrate as a measurement of performance has declined as the bottleneck in graphics applications has shifted. For example, today, the number of pixel shader
units has gained attention.
請問..係咪即係iphone 3GS 會係圖像或影像上會慢一點?
