GeForce GTX 275 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which features a GPU core clock speed of 1175 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is comprised of 1024 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
GeForce GTX 275		219 Watts
	Difference: 139 Watts (174%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 275 should be 11% quicker than the Radeon RX 560 in general, due to its greater data rate. (explain)

GeForce GTX 275		127008 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 12320 (11%)

Texel Rate

The Radeon RX 560 will be quite a bit (about 48%) better at anisotropic filtering than the GeForce GTX 275. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 275		50640 Mtexels/sec
	Difference: 24560 (48%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 560 is the winner, but only just. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 1076 (6%)

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 (in units of megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, 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 maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
