GeForce GTX 275 vs Radeon RX 560

Intro

Compare that to the Radeon RX 560, which features a core clock frequency of 1175 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit memory bus, and makes use of a 14 nm design. It is made up of 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

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 is 11% quicker than the Radeon RX 560 in general, due to its greater bandwidth. (explain)

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

Texel Rate

The Radeon RX 560 is much (more or less 48%) more effective at texture 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 running with high levels of AA is important to you, then the Radeon RX 560 is superior to the GeForce GTX 275, but it probably won't make a huge difference. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many 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.
