GeForce GTX 1050 3GB vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which comes with GPU core speed of 1175 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

GeForce GTX 1050 3GB		75 Watts
Radeon RX 560		80 Watts
	Difference: 5 Watts (7%)

Memory Bandwidth

As far as performance goes, the Radeon RX 560 should in theory be quite a bit better than the GeForce GTX 1050 3GB overall. (explain)

Radeon RX 560		114688 MB/sec
GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 28672 (33%)

Texel Rate

The Radeon RX 560 should be just a bit (about 13%) better at texture filtering than the GeForce GTX 1050 3GB. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 1050 3GB		66816 Mtexels/sec
	Difference: 8384 (13%)

Pixel Rate

The GeForce GTX 1050 3GB should be quite a bit (more or less 78%) more effective at AA than the Radeon RX 560, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 14608 (78%)

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 information (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, 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 amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs 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 rate also depends on quite a few 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.
