GeForce GTX 460 1GB vs GeForce GTX 880M

Intro

The GeForce GTX 460 1GB makes use of a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 memory is set to run at a speed of 900 MHz on this specific card. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.

Compare all that to the GeForce GTX 880M, which makes use of a 28 nm design. nVidia has set the core speed at 954 MHz. The GDDR5 memory works at a speed of 1000 MHz on this card. It features 1536 SPUs as well as 128 TAUs and 32 ROPs.

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

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
