Geforce GTX 780 vs Radeon RX 480 4GB

Intro

The Geforce GTX 780 makes use of a 28 nm design. nVidia has set the core frequency at 863 MHz. The GDDR5 memory is set to run at a speed of 1502 MHz on this model. It features 2304 SPUs as well as 192 Texture Address Units and 48 ROPs.

Compare those specifications to the Radeon RX 480 4GB, which features core clock speeds of 1120 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
