Geforce GTX 670 vs Radeon RX 480 4GB

Intro

The Geforce GTX 670 comes with a core clock frequency of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1344 SPUs, 112 Texture Address Units, and 32 ROPs.

Compare those specs to the Radeon RX 480 4GB, which comes with 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 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total number 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
