GeForce GTX Titan X vs Radeon R7 M265

Intro

The GeForce GTX Titan X makes use of a 28 nm design. nVidia has set the core frequency at 1000 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this particular model. It features 3072 SPUs as well as 192 Texture Address Units and 96 Rasterization Operator Units.

Compare those specifications to the Radeon R7 M265, which comes with GPU core speed of 725 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video 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 the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
