GeForce GTX 750 vs Radeon RX 480 4GB

Intro

The GeForce GTX 750 has a GPU clock speed of 1020 MHz, and the 1024 MB of GDDR5 memory runs at 1250 MHz through a 128-bit bus. It also is made up of 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Compare those specifications to the Radeon RX 480 4GB, which features GPU core speed of 1120 MHz, and 4096 MB of GDDR5 memory running at 1750 MHz through a 256-bit bus. It also features 2304 SPUs, 144 TAUs, and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. 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 rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
