GeForce GTX 1080 vs GeForce GTX 970M

Intro

The GeForce GTX 1080 has a GPU core speed of 1607 MHz, and the 8192 MB of GDDR5X RAM runs at 1251 MHz through a 256-bit bus. It also features 2560 Stream Processors, 160 Texture Address Units, and 64 ROPs.

Compare all of that to the GeForce GTX 970M, which has core speeds of 924 MHz on the GPU, and 1000 MHz on the 3072 MB of GDDR5 RAM. It features 1280 SPUs along with 80 TAUs and 48 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per 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 higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
