GeForce GTX 1070 vs GeForce GTX 970

Intro

The GeForce GTX 1070 features a GPU core speed of 1506 MHz, and the 8192 MB of GDDR5 memory runs at 2000 MHz through a 256-bit bus. It also is comprised of 1920 SPUs, 120 Texture Address Units, and 64 ROPs.

Compare that to the GeForce GTX 970, which comes with a core clock speed of 1050 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1664 SPUs, 104 Texture Address Units, and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
