GeForce GT 130 vs GeForce GTX 580 3GB

Intro

The GeForce GT 130 makes use of a 55 nm design. nVidia has clocked the core speed at 500 MHz. The DDR2 RAM is set to run at a speed of 250 MHz on this model. It features 48 SPUs as well as 24 Texture Address Units and 16 ROPs.

Compare that to the GeForce GTX 580 3GB, which uses a 40 nm design. nVidia has set the core frequency at 772 MHz. The GDDR5 RAM is set to run at a speed of 1002 MHz on this model. It features 512 SPUs as well as 64 Texture Address Units and 48 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
