Geforce GTX 680 vs Radeon RX 480 4GB

Intro

The Geforce GTX 680 has a core clock frequency of 1006 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.

Compare those specs to the Radeon RX 480 4GB, which comes with core speeds of 1120 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 2304 SPUs along with 144 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video 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 maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
