GeForce GT 130 vs Radeon HD 4550 256MB

Intro

The GeForce GT 130 comes with a core clock frequency of 500 MHz and a DDR2 memory frequency of 250 MHz. It also features a 192-bit bus, and makes use of a 55 nm design. It features 48 SPUs, 24 TAUs, and 16 ROPs.

Compare those specs to the Radeon HD 4550 256MB, which comes with GPU clock speed of 600 MHz, and 256 MB of DDR3 memory set to run at 800 MHz through a 64-bit bus. It also is comprised of 80(16x5) Stream Processors, 8 TAUs, and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
