Geforce GTX 770 vs Radeon RX 480

Intro

The Geforce GTX 770 features a GPU core clock speed of 1046 MHz, and the 2048 MB of GDDR5 memory runs at 1753 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 128 TAUs, and 32 Raster Operation Units.

Compare those specifications to the Radeon RX 480, which uses a 14 nm design. AMD has clocked the core frequency at 1120 MHz. The GDDR5 memory is set to run at a speed of 2000 MHz on this card. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
