GeForce GTX 1080 vs Geforce GTX 770

Intro

The GeForce GTX 1080 makes use of a 16 nm design. nVidia has set the core frequency at 1607 MHz. The GDDR5X RAM is set to run at a frequency of 1251 MHz on this specific card. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Compare all that to the Geforce GTX 770, which uses a 28 nm design. nVidia has clocked the core speed at 1046 MHz. The GDDR5 RAM is set to run at a speed of 1753 MHz on this particular model. It features 1536 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
