GeForce GTX 560 Ti vs Radeon R9 M385X

Intro

Compare that to the Radeon R9 M385X, which comes with a GPU core clock speed of 1100 MHz, and 4096 MB of GDDR5 memory running at 1500 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 Ti should be a lot faster than the Radeon R9 M385X overall. (explain)

GeForce GTX 560 Ti		128256 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 32256 (34%)

Texel Rate

The Radeon R9 M385X is a small bit (more or less 17%) better at anisotropic filtering than the GeForce GTX 560 Ti. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GTX 560 Ti		52608 Mtexels/sec
	Difference: 8992 (17%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 560 Ti is the winner, and very much so. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 8704 (49%)

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 (in units of megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
