GeForce GTS 250 512MB vs Radeon HD 5670
Intro
The GeForce GTS 250 512MB has a clock speed of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also uses a 256-bit memory bus, and makes use of a 65/55 nm design. It features 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare that to the Radeon HD 5670, which comes with GPU core speed of 775 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is comprised of 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
