Geforce GTX 680 vs Radeon RX 480 4GB

Intro

The Geforce GTX 680 makes use of a 28 nm design. nVidia has set the core frequency at 1006 MHz. The GDDR5 memory is set to run at a speed of 1502 MHz on this card. It features 1536 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Compare that to the Radeon RX 480 4GB, which has a core clock frequency of 1120 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 256-bit bus, and makes use of a 14 nm design. It features 2304 SPUs, 144 TAUs, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen 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 graphics 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 number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
