GeForce GTX Titan vs Radeon RX 590

Intro

Compare all of that to the Radeon RX 590, which has GPU clock speed of 1469 MHz, and 8192 MB of GDDR5 RAM set to run at 2000 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 Texture Address Units, and 32 ROPs.

Radeon RX 590		262144 MB/sec
	Difference: 26240 (10%)

Texel Rate

The Radeon RX 590 is a small bit (about 13%) more effective at anisotropic filtering than the GeForce GTX Titan. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX Titan		187488 Mtexels/sec
	Difference: 24048 (13%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 590 is a better choice, though only just barely. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce GTX Titan		40176 Mpixels/sec
	Difference: 6832 (17%)

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 (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high 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 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 ability to reach the max fill rate.
