Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.

2 Responses to “GeForce GTX 480 vs GeForce GTX 550 Ti”Hello,
Thank you for this information. I have the GTX 550 ti but i couldn't run battlefield 3 well. And i want to now the following things, the GTX 550 ti has more GHz at Clock and Processor than GTX 480 but that's not the point right? Because GTX 480 is better and faster instead of the 550 ti (i heard and saw on youtube)
So is the GTX 480 will perform better in games like Battlefield 3 than a GTX 550 ti?
Thanks!
@Mitch
Sure,the Gtx 480 is very powerfull.
