GeForce GTX 780 Ti vs Radeon R7 M260

Intro

The GeForce GTX 780 Ti comes with a core clock frequency of 875 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 384-bit memory bus, and uses a 28 nm design. It is comprised of 2880 SPUs, 240 TAUs, and 48 ROPs.

Compare that to the Radeon R7 M260, which features a clock frequency of 715 MHz and a DDR3 memory frequency of 1000 MHz. It also features a 64-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
