GeForce GTX 560 vs Radeon RX 460 2GB

Intro

Compare those specs to the Radeon RX 460 2GB, which has GPU core speed of 1090 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Radeon RX 460 2GB		75 Watts
GeForce GTX 560		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 will be 14% faster than the Radeon RX 460 2GB in general, due to its greater bandwidth. (explain)

GeForce GTX 560		128128 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 16128 (14%)

Texel Rate

The Radeon RX 460 2GB will be a lot (more or less 35%) more effective at texture filtering than the GeForce GTX 560. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GTX 560		45360 Mtexels/sec
	Difference: 15680 (35%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 560 is a better choice, by far. (explain)

GeForce GTX 560		25920 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 8480 (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 largest amount of information (counted in MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, 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 number is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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