GeForce GTX 580 vs Radeon RX 590

Intro

Compare those specs to the Radeon RX 590, which makes use of a 12 nm design. AMD has set the core speed at 1469 MHz. The GDDR5 RAM runs at a frequency of 2000 MHz on this model. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

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

The Radeon RX 590 should theoretically perform a lot faster than the GeForce GTX 580 in general. (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 texture filtering than the GeForce GTX 580. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 590 is a better choice, by a large margin. (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: Bandwidth is the largest amount of data (counted in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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