GeForce GTX 1080 vs Geforce GTX 780

Intro

The GeForce GTX 1080 has a clock frequency of 1607 MHz and a GDDR5X memory speed of 1251 MHz. It also makes use of a 256-bit memory bus, and uses a 16 nm design. It is made up of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Compare all of that to the Geforce GTX 780, which uses a 28 nm design. nVidia has clocked the core frequency at 863 MHz. The GDDR5 memory works at a speed of 1502 MHz on this card. It features 2304 SPUs as well as 192 Texture Address Units and 48 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock 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 - the lower the bandwidth is, the lower the potential to get to the max fill rate.
