GeForce GTX 560 vs Radeon R9 M395X

Intro

Compare those specs to the Radeon R9 M395X, which has GPU clock speed of 723 MHz, and 4096 MB of GDDR5 memory set to run at 1250 MHz through a 256-bit bus. It also features 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M395X		125 Watts
GeForce GTX 560		150 Watts
	Difference: 25 Watts (20%)

Memory Bandwidth

The Radeon R9 M395X should in theory be much faster than the GeForce GTX 560 in general. (explain)

Radeon R9 M395X		160000 MB/sec
GeForce GTX 560		128128 MB/sec
	Difference: 31872 (25%)

Texel Rate

The Radeon R9 M395X should be quite a bit (more or less 104%) better at anisotropic filtering than the GeForce GTX 560. (explain)

Radeon R9 M395X		92544 Mtexels/sec
GeForce GTX 560		45360 Mtexels/sec
	Difference: 47184 (104%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 560 is superior to the Radeon R9 M395X, but it probably won't make a huge difference. (explain)

GeForce GTX 560		25920 Mpixels/sec
Radeon R9 M395X		23136 Mpixels/sec
	Difference: 2784 (12%)

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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 potential to reach the maximum fill rate.
