GeForce GTX 590 vs Radeon RX 460 2GB

Intro

Compare all of that to the Radeon RX 460 2GB, which comes with core clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Radeon RX 460 2GB		75 Watts
GeForce GTX 590		365 Watts
	Difference: 290 Watts (387%)

Memory Bandwidth

The GeForce GTX 590 should in theory perform quite a bit faster than the Radeon RX 460 2GB in general. (explain)

GeForce GTX 590		328320 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 216320 (193%)

Texel Rate

The GeForce GTX 590 is quite a bit (approximately 27%) better at texture filtering than the Radeon RX 460 2GB. (explain)

GeForce GTX 590		77696 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 16656 (27%)

Pixel Rate

The GeForce GTX 590 should be a lot (more or less 234%) more effective at anti-aliasing than the Radeon RX 460 2GB, and will be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 590		58272 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 40832 (234%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
