GeForce GTX 880M vs Radeon R7 260X

Intro

The GeForce GTX 880M makes use of a 28 nm design. nVidia has set the core frequency at 954 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this particular model. It features 1536 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Compare all of that to the Radeon R7 260X, which uses a 28 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 RAM is set to run at a frequency of 1625 MHz on this specific card. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher 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 most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
