GeForce GTX 650 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which comes with core clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 1024 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650		64 Watts
Radeon RX 560		80 Watts
	Difference: 16 Watts (25%)

Memory Bandwidth

In theory, the Radeon RX 560 is 43% quicker than the GeForce GTX 650 in general, because of its greater bandwidth. (explain)

Radeon RX 560		114688 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 34688 (43%)

Texel Rate

The Radeon RX 560 will be a lot (about 122%) more effective at AF than the GeForce GTX 650. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 41344 (122%)

Pixel Rate

The Radeon RX 560 will be just a bit (about 11%) more effective at full screen anti-aliasing than the GeForce GTX 650, and also should be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 1872 (11%)

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

Texel Rate: Texel rate is the maximum amount 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 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 most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
