What's the meaning of crossfire technologies
At that web site there is some line that speak about the cross fire
technologies and it say something about 12 processor pixel shaderand a peak fill rate of 2.36gb/s. Does it mean that i should multypli the 12 by the 2.36Gb/s and by that getting 28 Gb/s of pixel fill rate. That would be great for that card vs all the other sold at the double of it's price? http://www.msicomputer.com/product/p...256E&class=vga |

No. You are confusing ATI's "crossfire" approach to using multiple GPUs with the number of pixel shaders in a single GPU. The 1600XT has twelve pixel shaders and a peak fill rate of 2.36GB/s. It can be used in conjunction with another 1600XT in a "crossfire" configuration on a crossfire motherboard. Crossfire allows each card's gpu to render alternate frames (and supports other ways of two cards sharing the load - scissoring and tiling) thereby speeding up the frame rate. However, even two cards are not going to be able to exceed their combined max fill rate and with the overheads involved in processing in a two-card set up their combined fill rate is likely to be substantially less than the theoretical max of 4.72GB/s -- Tony -- Tony |
