GeForce GTX 780 Ti vs GeForce GTX 970M

Intro

The GeForce GTX 780 Ti makes use of a 28 nm design. nVidia has set the core speed at 875 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this particular model. It features 2880 SPUs as well as 240 Texture Address Units and 48 Rasterization Operator Units.

Compare those specs to the GeForce GTX 970M, which has GPU clock speed of 924 MHz, and 3072 MB of GDDR5 RAM running at 1000 MHz through a 192-bit bus. It also features 1280 Stream Processors, 80 TAUs, and 48 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
