GeForce GTX 460 vs GeForce GTX 870M

Intro

The GeForce GTX 460 uses a 40 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR5 memory runs at a speed of 900 MHz on this specific card. It features 336 SPUs as well as 56 Texture Address Units and 24 Rasterization Operator Units.

Compare those specs to the GeForce GTX 870M, which features a GPU core clock speed of 941 MHz, and 3072 MB of GDDR5 RAM set to run at 1000 MHz through a 192-bit bus. It also features 1344 SPUs, 112 TAUs, and 24 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
