GeForce GTX 560 Ti vs Radeon HD 7870 XT

Intro

The GeForce GTX 560 Ti uses a 40 nm design. nVidia has set the core frequency at 822 MHz. The GDDR5 memory runs at a speed of 1002 MHz on this specific card. It features 384 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Compare all that to the Radeon HD 7870 XT, which has GPU clock speed of 925 MHz, and 2048 MB of GDDR5 memory running at 1500 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 96 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. 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 quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
