GeForce GTS 250 1GB vs Radeon HD 4850 512MB
Intro
The GeForce GTS 250 1GB has a GPU core speed of 738 MHz, and the 1024 MB of GDDR3 RAM is set to run at 1100 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.Compare that to the Radeon HD 4850 512MB, which uses a 55 nm design. AMD has set the core frequency at 625 MHz. The GDDR3 memory works at a frequency of 993 MHz on this card. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 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 high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are 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 higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its 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 card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
