Nvidia Titan X vs Radeon RX 580

Intro

Compare those specs to the Radeon RX 580, which comes with a clock speed of 1257 MHz and a GDDR5 memory frequency of 2000 MHz. It also features a 256-bit bus, and makes use of a 14 nm design. It is made up of 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

	Difference: 136400 (75%)

Pixel Rate

The Nvidia Titan X will be much (approximately 238%) faster with regards to AA than the Radeon RX 580, and also able to handle higher resolutions while still performing well. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon RX 580		40224 Mpixels/sec
	Difference: 95808 (238%)

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 information (measured in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, 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 graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
