GeForce GTX 1070 vs GeForce GTX 1080

Intro

The GeForce GTX 1070 has core speeds of 1506 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 1920 SPUs along with 120 TAUs and 64 Rasterization Operator Units.

Compare those specs to the GeForce GTX 1080, which makes use of a 16 nm design. nVidia has set the core frequency at 1607 MHz. The GDDR5X memory is set to run at a speed of 1251 MHz on this model. It features 2560 SPUs along with 160 TAUs and 64 ROPs.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a 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 - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
