GeForce GTX Titan vs Radeon RX 590

Intro

Compare all that to the Radeon RX 590, which features GPU clock speed of 1469 MHz, and 8192 MB of GDDR5 memory running at 2000 MHz through a 256-bit bus. It also is comprised of 2304 SPUs, 144 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590		175 Watts
GeForce GTX Titan		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

The GeForce GTX Titan should theoretically be a small bit faster than the Radeon RX 590 in general. (explain)

GeForce GTX Titan		288384 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 26240 (10%)

Texel Rate

The Radeon RX 590 is a bit (approximately 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 using high levels of AA is important to you, then the Radeon RX 590 is the winner, but not by far. (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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the 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 can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core 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 rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
