GeForce GTX 560 Ti vs Radeon R9 M395X

Intro

Compare those specifications to the Radeon R9 M395X, which has a core clock speed of 723 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Radeon R9 M395X		125 Watts
GeForce GTX 560 Ti		170 Watts
	Difference: 45 Watts (36%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 M395X is 25% faster than the GeForce GTX 560 Ti in general, due to its greater bandwidth. (explain)

Radeon R9 M395X		160000 MB/sec
GeForce GTX 560 Ti		128256 MB/sec
	Difference: 31744 (25%)

Texel Rate

The Radeon R9 M395X will be much (approximately 76%) more effective at anisotropic filtering than the GeForce GTX 560 Ti. (explain)

Radeon R9 M395X		92544 Mtexels/sec
GeForce GTX 560 Ti		52608 Mtexels/sec
	Difference: 39936 (76%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 560 Ti is the winner, though not by far. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
Radeon R9 M395X		23136 Mpixels/sec
	Difference: 3168 (14%)

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 maximum amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 are applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could 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 colour ROPs by the the core 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
