Geforce GTX 780 vs Radeon HD 5870

Intro

The Geforce GTX 780 has a GPU core clock speed of 863 MHz, and the 3072 MB of GDDR5 memory runs at 1502 MHz through a 384-bit bus. It also is comprised of 2304 SPUs, 192 TAUs, and 48 Raster Operation Units.

Compare all of that to the Radeon HD 5870, which has GPU core speed of 850 MHz, and 1024 MB of GDDR5 RAM set to run at 1200 MHz through a 256-bit bus. It also is comprised of 1600(320x5) SPUs, 80 TAUs, and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 processed in one 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 video 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 most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
