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

Intro

The GeForce GTX 260 216SP 55 nm makes use of a 55 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 memory works at a speed of 999 MHz on this model. It features 216 SPUs along with 72 TAUs and 28 Rasterization Operator Units.

Compare all of that to the GeForce GTX 870M, which features a core clock speed of 941 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 192-bit memory bus, and uses a 28 nm design. It is made up of 1344 SPUs, 112 TAUs, and 24 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the interface 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 better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 number 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 calculated by multiplying the number of Render Output Units 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
