GeForce GTX 580 vs GeForce GTX 660 Ti

Intro

The GeForce GTX 580 makes use of a 40 nm design. nVidia has clocked the core speed at 772 MHz. The GDDR5 RAM is set to run at a speed of 1002 MHz on this card. It features 512 SPUs as well as 64 TAUs and 48 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 660 Ti, which features GPU clock speed of 915 MHz, and 2048 MB of GDDR5 RAM running at 1500 MHz through a 192-bit bus. It also features 1344 SPUs, 112 Texture Address Units, and 24 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

Just a little correction.
The power difference or 94 watts is 38.5 % of the 580
[...] it must be instantly better. I5 is for gaming I7 is for hard core multi tasking I believe. Stats: GeForce GTX 580 vs GeForce GTX 660 Ti – Performance Comparison Benchmarks @ Hardware Compare [...]
