GeForce GTX 1050 3GB vs Radeon RX 580

Intro

Compare all of that to the Radeon RX 580, which has a clock speed of 1257 MHz and a GDDR5 memory frequency of 2000 MHz. It also uses a 256-bit memory bus, and uses a 14 nm design. It is comprised of 2304 SPUs, 144 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050 3GB		75 Watts
Radeon RX 580		185 Watts
	Difference: 110 Watts (147%)

Memory Bandwidth

In theory, the Radeon RX 580 should be 205% quicker than the GeForce GTX 1050 3GB overall, because of its higher data rate. (explain)

Radeon RX 580		262144 MB/sec
GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 176128 (205%)

Texel Rate

The Radeon RX 580 will be quite a bit (approximately 171%) faster with regards to AF than the GeForce GTX 1050 3GB. (explain)

Radeon RX 580		181008 Mtexels/sec
GeForce GTX 1050 3GB		66816 Mtexels/sec
	Difference: 114192 (171%)

Pixel Rate

The Radeon RX 580 should be just a bit (about 20%) better at anti-aliasing than the GeForce GTX 1050 3GB, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 580		40224 Mpixels/sec
GeForce GTX 1050 3GB		33408 Mpixels/sec
	Difference: 6816 (20%)

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 max amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
