GeForce GT 130 vs Radeon HD 4550 256MB

Intro

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

Compare all of that to the Radeon HD 4550 256MB, which comes with 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 is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Texel Rate

The GeForce GT 130 is a lot (about 150%) more effective at texture filtering than the Radeon HD 4550 256MB. (explain)

GeForce GT 130 12000 Mtexels/sec
Radeon HD 4550 256MB 4800 Mtexels/sec
Difference: 7200 (150%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GT 130 is the winner, and very much so. (explain)

GeForce GT 130 8000 Mpixels/sec
Radeon HD 4550 256MB 2400 Mpixels/sec
Difference: 5600 (233%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at 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 the video card can possibly record to its 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 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
