Nvidia Titan X vs Radeon RX 580

Intro

Compare all of that to the Radeon RX 580, which has GPU clock speed of 1257 MHz, and 8192 MB of GDDR5 RAM set to run at 2000 MHz through a 256-bit bus. It also is comprised of 2304 SPUs, 144 TAUs, and 32 Raster Operation Units.

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Nvidia Titan X should be quite a bit faster than the Radeon RX 580 overall. (explain)

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

Texel Rate

The Nvidia Titan X is a lot (approximately 75%) more effective at AF 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 should be quite a bit (approximately 238%) more effective at FSAA 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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
