GeForce GTX 1050 3GB vs GeForce GTX 470

Intro

Compare all that to the GeForce GTX 470, which comes with GPU core speed of 607 MHz, and 1280 MB of GDDR5 memory set to run at 837 MHz through a 320-bit bus. It also is comprised of 448 Stream Processors, 56 TAUs, and 40 ROPs.

GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 47904 (56%)

Texel Rate

The GeForce GTX 1050 3GB should be a lot (about 97%) better at texture filtering than the GeForce GTX 470. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
GeForce GTX 470		33992 Mtexels/sec
	Difference: 32824 (97%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 1050 3GB is the winner, and very much so. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
GeForce GTX 470		24280 Mpixels/sec
	Difference: 9128 (38%)

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 MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
