GeForce GTX 1050 vs Radeon RX 560

Intro

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

Texel Rate

The Radeon RX 560 is a lot (more or less 39%) more effective at texture filtering 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 resolution is important to you, then the GeForce GTX 1050 is superior to the Radeon RX 560, 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 largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
