GeForce GTX 260 216SP 55 nm vs GeForce GTX 870M

Intro

The GeForce GTX 260 216SP 55 nm has a clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also makes use of a 448-bit bus, and uses a 55 nm design. It is comprised of 216 SPUs, 72 Texture Address Units, and 28 Raster Operation Units.

Compare all that to the GeForce GTX 870M, which features a GPU core clock speed of 941 MHz, and 3072 MB of GDDR5 memory running at 1000 MHz through a 192-bit bus. It also is made up of 1344 Stream Processors, 112 Texture Address Units, and 24 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends 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 maximum fill rate.
