GeForce GTX 580 3GB vs Geforce GTX 770

Intro

The GeForce GTX 580 3GB has a GPU clock speed of 772 MHz, and the 3072 MB of GDDR5 RAM is set to run at 1002 MHz through a 384-bit bus. It also features 512 SPUs, 64 TAUs, and 48 Raster Operation Units.

Compare those specifications to the Geforce GTX 770, which features GPU clock speed of 1046 MHz, and 2048 MB of GDDR5 memory set to run at 1753 MHz through a 256-bit bus. It also features 1536 Stream Processors, 128 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 potential to get to the maximum fill rate.
