GeForce GT 130 vs GeForce GTX 480

Intro

The GeForce GT 130 features a clock speed of 500 MHz and a DDR2 memory frequency of 250 MHz. It also makes use of a 192-bit memory bus, and makes use of a 55 nm design. It is made up of 48 SPUs, 24 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the GeForce GTX 480, which features a clock frequency of 700 MHz and a GDDR5 memory frequency of 924 MHz. It also uses a 384-bit bus, and uses a 40 nm design. It features 480 SPUs, 60 TAUs, and 48 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
