GeForce GTX 1070 Ti vs Radeon RX 590

Intro

Compare that to the Radeon RX 590, which features a GPU core clock speed of 1469 MHz, and 8192 MB of GDDR5 memory running at 2000 MHz through a 256-bit bus. It also features 2304 Stream Processors, 144 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590		175 Watts
GeForce GTX 1070 Ti		180 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

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

Texel Rate

The GeForce GTX 1070 Ti is a small bit (approximately 15%) faster with regards to anisotropic filtering than the Radeon RX 590. (explain)

GeForce GTX 1070 Ti		244264 Mtexels/sec
Radeon RX 590		211536 Mtexels/sec
	Difference: 32728 (15%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1070 Ti is the winner, and very much so. (explain)

GeForce GTX 1070 Ti		102848 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 55840 (119%)

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 largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high 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 amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
