GeForce GTX 1080 vs Radeon R9 390X 8G

Intro

The GeForce GTX 1080 makes use of a 16 nm design. nVidia has clocked the core speed at 1607 MHz. The GDDR5X memory is set to run at a frequency of 1251 MHz on this specific card. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Compare those specs to the Radeon R9 390X 8G, which comes with a GPU core clock speed of 1050 MHz, and 8192 MB of GDDR5 RAM set to run at 1500 MHz through a 512-bit bus. It also is comprised of 2816 SPUs, 176 Texture Address Units, and 64 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
