GeForce GTX 470 vs GeForce GTX 880M

Intro

The GeForce GTX 470 has a GPU core speed of 607 MHz, and the 1280 MB of GDDR5 RAM is set to run at 837 MHz through a 320-bit bus. It also is made up of 448 Stream Processors, 56 Texture Address Units, and 40 Raster Operation Units.

Compare those specs to the GeForce GTX 880M, which comes with a clock frequency of 954 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is made up of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
