GeForce GTX 1070 vs Radeon RX 590

Intro

Compare those specs to the Radeon RX 590, which has a clock frequency of 1469 MHz and a GDDR5 memory speed of 2000 MHz. It also makes use of a 256-bit bus, and uses a 12 nm design. It 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 the exact same bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon RX 590 should be a bit (about 17%) more effective 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

If using lots of anti-aliasing is important to you, then the GeForce GTX 1070 is a better choice, by a large margin. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
