Radeon R9 M375X		72000 MB/sec
	Difference: 216384 (301%)

Texel Rate

The GeForce GTX Titan is a lot (approximately 362%) faster with regards to AF than the Radeon R9 M375X. (explain)

GeForce GTX Titan		187488 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 146888 (362%)

Pixel Rate

The GeForce GTX Titan is quite a bit (about 147%) faster with regards to full screen anti-aliasing than the Radeon R9 M375X, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX Titan		40176 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 23936 (147%)

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 largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
