GeForce GTX 1050 vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which makes use of a 14 nm design. AMD has clocked the core speed at 1175 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this model. It features 1024 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050		75 Watts
Radeon RX 560		80 Watts
	Difference: 5 Watts (7%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The Radeon RX 560 should be quite a bit (more or less 39%) more effective at AF than the GeForce GTX 1050. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 1050		54160 Mtexels/sec
	Difference: 21040 (39%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1050 is the winner, by a large margin. (explain)

GeForce GTX 1050		43328 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 24528 (130%)

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 information (measured in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video 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 most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few 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.
