GeForce GTX Titan X vs Radeon R7 M260X

Intro

Compare all that to the Radeon R7 M260X, which uses a 28 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this particular model. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX Titan X should in theory be quite a bit superior to the Radeon R7 M260X overall. (explain)

GeForce GTX Titan X		336000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 272000 (425%)

Texel Rate

The GeForce GTX Titan X should be much (more or less 870%) more effective at anisotropic filtering than the Radeon R7 M260X. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 172200 (870%)

Pixel Rate

The GeForce GTX Titan X is much (more or less 1355%) better at full screen anti-aliasing than the Radeon R7 M260X, and should be able to handle higher resolutions more effectively. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 89400 (1355%)

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

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount 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 a second.

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