GeForce GTX 650 vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which makes use of a 14 nm design. AMD has set the core speed at 1175 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this particular model. 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

Theoretically speaking, the Radeon RX 560 will be 43% faster than the GeForce GTX 650 overall, because of its greater data rate. (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 (approximately 122%) more effective at texture filtering than the GeForce GTX 650. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 560 is a better choice, but it probably won't make a huge difference. (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 max amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
