GeForce GTX 560 Ti vs Radeon HD 7870 XT

Intro

The GeForce GTX 560 Ti comes with a GPU core speed of 822 MHz, and the 1024 MB of GDDR5 RAM runs at 1002 MHz through a 256-bit bus. It also features 384 Stream Processors, 64 TAUs, and 32 ROPs.

Compare all of that to the Radeon HD 7870 XT, which uses a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this specific card. It features 1536 SPUs as well as 96 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
