GeForce GTX Titan X 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 memory set to run at 2000 MHz through a 256-bit bus. It also features 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce GTX Titan X should be a lot faster than the Radeon RX 590 overall. (explain)

GeForce GTX Titan X		336000 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 73856 (28%)

Texel Rate

The Radeon RX 590 will be a small bit (more or less 10%) more effective at AF than the GeForce GTX Titan X. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX Titan X		192000 Mtexels/sec
	Difference: 19536 (10%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX Titan X is superior to the Radeon RX 590, and very much so. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 48992 (104%)

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 max amount of data (counted in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
