Radeon RX 470 4GB		211200 MB/sec
	Difference: 124800 (59%)

Texel Rate

The GeForce GTX Titan Black should be a lot (approximately 80%) better at anisotropic filtering than the Radeon RX 470 4GB. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 94832 (80%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX Titan Black is a better choice, by a large margin. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 13040 (44%)

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 largest amount of information (measured in MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
