GeForce GTX Titan X		336000 MB/sec
	Difference: 304000 (90%)

Texel Rate

The Radeon R9 295X2 should be a lot (more or less 87%) more effective at texture filtering than the GeForce GTX Titan X. (explain)

Radeon R9 295X2		358336 Mtexels/sec
GeForce GTX Titan X		192000 Mtexels/sec
	Difference: 166336 (87%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 295X2 is a better choice, and very much so. (explain)

Radeon R9 295X2		130304 Mpixels/sec
GeForce GTX Titan X		96000 Mpixels/sec
	Difference: 34304 (36%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
