GeForce GTX 580 vs Radeon RX 590

Intro

Compare those specifications to the Radeon RX 590, which comes with a GPU core clock speed of 1469 MHz, and 8192 MB of GDDR5 RAM running at 2000 MHz through a 256-bit bus. It also is made up of 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590		175 Watts
GeForce GTX 580		244 Watts
	Difference: 69 Watts (39%)

Memory Bandwidth

In theory, the Radeon RX 590 is 36% faster than the GeForce GTX 580 in general, because of its higher bandwidth. (explain)

Radeon RX 590		262144 MB/sec
GeForce GTX 580		192384 MB/sec
	Difference: 69760 (36%)

Texel Rate

The Radeon RX 590 is quite a bit (more or less 328%) more effective at AF than the GeForce GTX 580. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 162128 (328%)

Pixel Rate

The Radeon RX 590 should be a lot (about 27%) more effective at full screen anti-aliasing than the GeForce GTX 580, and also should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce GTX 580		37056 Mpixels/sec
	Difference: 9952 (27%)

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 data (in units of MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the 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 maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
