GeForce GT 130 vs GeForce GTX 580

Intro

The GeForce GT 130 has a GPU core clock speed of 500 MHz, and the 768 MB of DDR2 RAM is set to run at 250 MHz through a 192-bit bus. It also features 48 Stream Processors, 24 TAUs, and 16 ROPs.

Compare that to the GeForce GTX 580, which has GPU clock speed of 772 MHz, and 1536 MB of GDDR5 memory set to run at 1002 MHz through a 384-bit bus. It also is comprised of 512 Stream Processors, 64 TAUs, and 48 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
