GeForce GTX 870M vs Radeon R7 260X

Intro

The GeForce GTX 870M comes with a GPU core speed of 941 MHz, and the 3072 MB of GDDR5 memory is set to run at 1000 MHz through a 192-bit bus. It also is made up of 1344 Stream Processors, 112 TAUs, and 24 Raster Operation Units.

Compare those specifications to the Radeon R7 260X, which features core clock speeds of 1100 MHz on the GPU, and 1625 MHz on the 2048 MB of GDDR5 RAM. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 applied 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 higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
