Nvidia Titan X vs Radeon RX 470

Intro

Compare those specifications to the Radeon RX 470, which features GPU core speed of 926 MHz, and 8192 MB of GDDR5 memory running at 1650 MHz through a 256-bit bus. It also features 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470		120 Watts
Nvidia Titan X		250 Watts
	Difference: 130 Watts (108%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X should be quite a bit faster than the Radeon RX 470 overall. (explain)

Nvidia Titan X		491520 MB/sec
Radeon RX 470		211200 MB/sec
	Difference: 280320 (133%)

Texel Rate

The Nvidia Titan X will be much (approximately 168%) more effective at texture filtering than the Radeon RX 470. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon RX 470		118528 Mtexels/sec
	Difference: 198880 (168%)

Pixel Rate

If using a high resolution is important to you, then the Nvidia Titan X is the winner, by far. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon RX 470		29632 Mpixels/sec
	Difference: 106400 (359%)

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 (in units of megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
