Nvidia Titan X vs Radeon R7 260X

Intro

Compare all that to the Radeon R7 260X, which comes with 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 ROPs.

Radeon R7 260X		104000 MB/sec
	Difference: 387520 (373%)

Texel Rate

The Nvidia Titan X should be much (more or less 415%) better at texture filtering than the Radeon R7 260X. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R7 260X		61600 Mtexels/sec
	Difference: 255808 (415%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Nvidia Titan X is a better choice, by a large margin. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R7 260X		17600 Mpixels/sec
	Difference: 118432 (673%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
