GeForce GTX 980 Ti vs GeForce GTX Titan Black

Intro

Compare all that to the GeForce GTX Titan Black, which makes use of a 28 nm design. nVidia has clocked the core speed at 889 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this card. It features 2880 SPUs as well as 240 Texture Address Units and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have the exact same memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The GeForce GTX Titan Black should be much (more or less 21%) better at AF than the GeForce GTX 980 Ti. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 37360 (21%)

Pixel Rate

The GeForce GTX 980 Ti will be much (about 125%) better at anti-aliasing than the GeForce GTX Titan Black, and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 980 Ti		96000 Mpixels/sec
GeForce GTX Titan Black		42672 Mpixels/sec
	Difference: 53328 (125%)

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 (measured in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core clock 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 amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
