GeForce GTX 260 216SP 55 nm vs Radeon HD 4890 2GB
Intro
The GeForce GTX 260 216SP 55 nm makes use of a 55 nm design. nVidia has set the core speed at 576 MHz. The GDDR3 RAM is set to run at a speed of 999 MHz on this particular model. It features 216 SPUs as well as 72 Texture Address Units and 28 Rasterization Operator Units.Compare those specifications to the Radeon HD 4890 2GB, which makes use of a 55 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM works at a speed of 975 MHz on this specific model. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
