GeForce GTX 460 2GB vs GeForce GTX 750

Intro

The GeForce GTX 460 2GB comes with a GPU core clock speed of 675 MHz, and the 2048 MB of GDDR5 memory runs at 900 MHz through a 256-bit bus. It also is comprised of 336 SPUs, 56 TAUs, and 32 ROPs.

Compare all of that to the GeForce GTX 750, which features GPU clock speed of 1020 MHz, and 1024 MB of GDDR5 memory running at 1250 MHz through a 128-bit bus. It also is comprised of 512 SPUs, 32 TAUs, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. It is calculated 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 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 bandwidth is, the lower the potential to reach the maximum fill rate.
