GeForce 9800 GT 1GB vs GeForce GTX 580 3GB
Intro
The GeForce 9800 GT 1GB has a core clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit bus, and makes use of a 65/55 nm design. It features 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the GeForce GTX 580 3GB, which makes use of a 40 nm design. nVidia has clocked the core speed at 772 MHz. The GDDR5 memory is set to run at a speed of 1002 MHz on this particular card. It features 512 SPUs as well as 64 TAUs and 48 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
