GeForce GTX 870M vs GeForce GTX 960

Intro

The GeForce GTX 870M makes use of a 28 nm design. nVidia has clocked the core frequency at 941 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific model. It features 1344 SPUs as well as 112 Texture Address Units and 24 Rasterization Operator Units.

Compare all of that to the GeForce GTX 960, which makes use of a 28 nm design. nVidia has set the core frequency at 1127 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this model. It features 1024 SPUs along with 64 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one 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 worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
