GeForce GTX 460 2GB vs GeForce GTX 660 Ti
Intro
The GeForce GTX 460 2GB has core speeds of 675 MHz on the GPU, and 900 MHz on the 2048 MB of GDDR5 RAM. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.Compare that to the GeForce GTX 660 Ti, which makes use of a 28 nm design. nVidia has clocked the core frequency at 915 MHz. The GDDR5 RAM runs at a frequency of 1500 MHz on this card. It features 1344 SPUs as well as 112 TAUs and 24 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics 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 that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
