GeForce GTX 880M vs Radeon R7 260X

Intro

The GeForce GTX 880M has a GPU core clock speed of 954 MHz, and the 4096 MB of GDDR5 RAM is set to run at 1000 MHz through a 256-bit bus. It also features 1536 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.

Compare all that 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 memory. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. 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 get to the max fill rate.
