GeForce GTS 250 1GB vs Radeon HD 4850 512MB
Intro
The GeForce GTS 250 1GB has a clock speed of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also makes use of a 256-bit bus, and uses a 65/55 nm design. It features 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare those specs to the Radeon HD 4850 512MB, which makes use of a 55 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR3 memory is set to run at a frequency of 993 MHz on this particular card. It features 800(160x5) SPUs along with 40 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen 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 texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
