GeForce GTX 560 Ti 448 vs Radeon HD 5850

Intro

The GeForce GTX 560 Ti 448 features a GPU core speed of 732 MHz, and the 1280 MB of GDDR5 RAM runs at 900 MHz through a 320-bit bus. It also is made up of 448 Stream Processors, 56 Texture Address Units, and 40 ROPs.

Compare those specifications to the Radeon HD 5850, which makes use of a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this model. It features 1440(288x5) SPUs along with 72 Texture Address Units and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If 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, 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 number is worked out 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 graphics 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 the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 maximum fill rate.
