Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470 4GB		120 Watts
GeForce GTX 590		365 Watts
	Difference: 245 Watts (204%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 590 will be 55% quicker than the Radeon RX 470 4GB overall, because of its higher bandwidth. (explain)

GeForce GTX 590		328320 MB/sec
Radeon RX 470 4GB		211200 MB/sec
	Difference: 117120 (55%)

Texel Rate

The Radeon RX 470 4GB should be a lot (more or less 53%) better at texture filtering than the GeForce GTX 590. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce GTX 590		77696 Mtexels/sec
	Difference: 40832 (53%)

Pixel Rate

The GeForce GTX 590 should be much (about 97%) more effective at AA than the Radeon RX 470 4GB, and will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 590		58272 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 28640 (97%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
