Geforce GTX 780 vs Radeon RX 480 4GB

Intro

The Geforce GTX 780 features a clock speed of 863 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 384-bit bus, and uses a 28 nm design. It is comprised of 2304 SPUs, 192 TAUs, and 48 Raster Operation Units.

Compare those specs to the Radeon RX 480 4GB, which comes with GPU core speed of 1120 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 256-bit bus. It also features 2304 Stream Processors, 144 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
