GeForce GTX 580 3GB vs GeForce GTX 660 Ti

Intro

The GeForce GTX 580 3GB uses a 40 nm design. nVidia has clocked the core speed at 772 MHz. The GDDR5 RAM is set to run at a frequency of 1002 MHz on this particular card. It features 512 SPUs along with 64 Texture Address Units and 48 ROPs.

Compare all that to the GeForce GTX 660 Ti, which comes with a clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 192-bit memory bus, and uses a 28 nm design. It features 1344 SPUs, 112 Texture Address Units, and 24 ROPs.

GeForce GTX 660 Ti 144000 MB/sec
Difference: 48384 (34%)

Texel Rate

The GeForce GTX 660 Ti will be quite a bit (approximately 107%) more effective at texture filtering than the GeForce GTX 580 3GB. (explain)

GeForce GTX 660 Ti 102480 Mtexels/sec
GeForce GTX 580 3GB 49408 Mtexels/sec
Difference: 53072 (107%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 580 3GB is a better choice, and very much so. (explain)

GeForce GTX 580 3GB 37056 Mpixels/sec
GeForce GTX 660 Ti 21960 Mpixels/sec
Difference: 15096 (69%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one 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 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 maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
