GeForce GTX 1070 vs Radeon RX 590

Intro

Compare all of that to the Radeon RX 590, which has core clock speeds of 1469 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs as well as 144 Texture Address Units and 32 Rasterization Operator Units.

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 memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Radeon RX 590 is a little bit (about 17%) better at AF 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 will be a lot (approximately 105%) better at AA than the Radeon RX 590, and should be capable of handling higher screen resolutions better. (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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 are applied per second. This figure 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
