Nvidia Titan X vs Radeon RX 580

Intro

Compare all of that to the Radeon RX 580, which uses a 14 nm design. AMD has clocked the core speed at 1257 MHz. The GDDR5 RAM works at a frequency of 2000 MHz on this card. It features 2304 SPUs as well as 144 TAUs and 32 Rasterization Operator Units.

Power Consumption (Max TDP)

Radeon RX 580		185 Watts
Nvidia Titan X		250 Watts
	Difference: 65 Watts (35%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X should be much faster than the Radeon RX 580 in general. (explain)

Nvidia Titan X		491520 MB/sec
Radeon RX 580		262144 MB/sec
	Difference: 229376 (88%)

Texel Rate

The Nvidia Titan X should be much (about 75%) faster with regards to anisotropic filtering than the Radeon RX 580. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon RX 580		181008 Mtexels/sec
	Difference: 136400 (75%)

Pixel Rate

The Nvidia Titan X will be quite a bit (approximately 238%) better at AA than the Radeon RX 580, and capable of handling higher screen 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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. It 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 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
