GeForce GTX 580 3GB vs Radeon HD 3470 512MB

Intro

The GeForce GTX 580 3GB comes with a core clock frequency of 772 MHz and a GDDR5 memory frequency of 1002 MHz. It also uses a 384-bit bus, and uses a 40 nm design. It is made up of 512 SPUs, 64 Texture Address Units, and 48 ROPs.

Compare all of that to the Radeon HD 3470 512MB, which features a clock frequency of 800 MHz and a GDDR3 memory frequency of 950 MHz. It also uses a 128-bit bus, and makes use of a 55 nm design. It is comprised of 40(8x5) SPUs, 4 Texture Address Units, and 4 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
