GeForce GTX 1050 vs GeForce GTX 580 3GB

Intro

Compare all that to the GeForce GTX 580 3GB, which uses a 40 nm design. nVidia has clocked the core frequency at 772 MHz. The GDDR5 RAM works at a frequency of 1002 MHz on this particular card. It features 512 SPUs along with 64 TAUs and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Performance-wise, the GeForce GTX 580 3GB should in theory be much superior to the GeForce GTX 1050 overall. (explain)

GeForce GTX 580 3GB		192384 MB/sec
GeForce GTX 1050		114688 MB/sec
	Difference: 77696 (68%)

Texel Rate

The GeForce GTX 1050 will be a bit (approximately 10%) faster with regards to AF than the GeForce GTX 580 3GB. (explain)

GeForce GTX 1050		54160 Mtexels/sec
GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 4752 (10%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 1050 is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 1050		43328 Mpixels/sec
GeForce GTX 580 3GB		37056 Mpixels/sec
	Difference: 6272 (17%)

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 largest amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
