GeForce GTX 1050 3GB vs GeForce GTX 580

Intro

Compare all of that to the GeForce GTX 580, which has a core clock speed of 772 MHz and a GDDR5 memory speed of 1002 MHz. It also uses a 384-bit bus, and uses a 40 nm design. It is comprised of 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050 3GB		75 Watts
GeForce GTX 580		244 Watts
	Difference: 169 Watts (225%)

Memory Bandwidth

In theory, the GeForce GTX 580 will be 124% quicker than the GeForce GTX 1050 3GB overall, because of its higher data rate. (explain)

GeForce GTX 580		192384 MB/sec
GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 106368 (124%)

Texel Rate

The GeForce GTX 1050 3GB will be much (about 35%) better at AF than the GeForce GTX 580. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 17408 (35%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 580 is superior to the GeForce GTX 1050 3GB, though only just barely. (explain)

GeForce GTX 580		37056 Mpixels/sec
GeForce GTX 1050 3GB		33408 Mpixels/sec
	Difference: 3648 (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 maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
