GeForce GTX 580 vs GeForce GTX 650 Ti

Intro

The GeForce GTX 580 has a clock speed of 772 MHz and a GDDR5 memory frequency of 1002 MHz. It also uses a 384-bit memory bus, and uses a 40 nm design. It features 512 SPUs, 64 TAUs, and 48 Raster Operation Units.

Compare those specs to the GeForce GTX 650 Ti, which has core clock speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 memory. It features 768 SPUs along with 64 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. 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 is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
