Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX Titan Black should in theory be quite a bit faster than the Radeon R9 M270X overall. (explain)

GeForce GTX Titan Black		336000 MB/sec
Radeon R9 M270X		72000 MB/sec
	Difference: 264000 (367%)

Texel Rate

The GeForce GTX Titan Black should be a lot (about 636%) more effective at AF than the Radeon R9 M270X. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 184360 (636%)

Pixel Rate

The GeForce GTX Titan Black should be a lot (approximately 268%) better at FSAA than the Radeon R9 M270X, and will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 31072 (268%)

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 (counted in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of 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 clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 potential to get to the max fill rate.
