GeForce GTX Titan X vs Radeon R9 280

Intro

The GeForce GTX Titan X comes with a core clock frequency of 1000 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 384-bit bus, and uses a 28 nm design. It is comprised of 3072 SPUs, 192 Texture Address Units, and 96 Raster Operation Units.

Compare all that to the Radeon R9 280, which makes use of a 28 nm design. AMD has set the core speed at 933 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this specific model. It features 1792 SPUs as well as 112 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
