GeForce GT 130 vs Radeon HD 4550 256MB

Intro

The GeForce GT 130 comes with 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 is comprised of 48 Stream Processors, 24 TAUs, and 16 ROPs.

Compare those specifications to the Radeon HD 4550 256MB, which has a clock frequency of 600 MHz and a DDR3 memory frequency of 800 MHz. It also features a 64-bit memory bus, and uses a 55 nm design. It features 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
