GeForce GTX 1070 vs Radeon RX 590

Intro

Compare all of that 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 features 2304 SPUs, 144 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1070		150 Watts
Radeon RX 590		175 Watts
	Difference: 25 Watts (17%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The Radeon RX 590 is a little bit (more or less 17%) better at texture filtering than the GeForce GTX 1070. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 1070		180720 Mtexels/sec
	Difference: 30816 (17%)

Pixel Rate

The GeForce GTX 1070 is much (about 105%) faster with regards to AA than the Radeon RX 590, and also will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 1070		96384 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 49376 (105%)

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 maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
