Nvidia Titan X vs Radeon RX 470

Intro

Compare those specifications to the Radeon RX 470, which has a clock frequency of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also makes use of a 256-bit bus, and uses a 14 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Radeon RX 470		211200 MB/sec
	Difference: 280320 (133%)

Texel Rate

The Nvidia Titan X will be much (about 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

The Nvidia Titan X will be quite a bit (more or less 359%) faster with regards to full screen anti-aliasing than the Radeon RX 470, and also able to handle higher resolutions without slowing down too much. (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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
