GeForce GTX Titan X vs Radeon R7 M260X

Intro

Compare 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

The GeForce GTX Titan X should theoretically perform much faster than the Radeon R7 M260X in general. (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 a lot (about 870%) more effective at texture 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 will be quite a bit (about 1355%) more effective at full screen anti-aliasing than the Radeon R7 M260X, and also will be able to handle higher screen resolutions better. (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 max amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
