GeForce GT 130 vs Radeon HD 4550 512MB

Intro

The GeForce GT 130 features a GPU core clock speed of 500 MHz, and the 768 MB of DDR2 memory 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 Radeon HD 4550 512MB, which has a core clock frequency of 600 MHz and a GDDR3 memory frequency of 800 MHz. It also features a 64-bit memory bus, and makes use of a 55 nm design. It is made up of 80(16x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
