Radeon R9 M370X		72000 MB/sec
	Difference: 264000 (367%)

Texel Rate

The GeForce GTX Titan Black should be a lot (about 567%) more effective at texture filtering than the Radeon R9 M370X. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 181360 (567%)

Pixel Rate

The GeForce GTX Titan Black is quite a bit (more or less 233%) more effective at anti-aliasing than the Radeon R9 M370X, and also will be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 29872 (233%)

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 (counted in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
