GeForce GTX 980 Ti vs GeForce GTX Titan Black

Intro

Compare that to the GeForce GTX Titan Black, which makes use of a 28 nm design. nVidia has set the core frequency at 889 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this particular card. It features 2880 SPUs along with 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 theoretically they should have identical performance. (explain)

Texel Rate

The GeForce GTX Titan Black should be a lot (about 21%) more effective 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 is a lot (more or less 125%) better at full screen anti-aliasing than the GeForce GTX Titan Black, and also should be able to handle higher resolutions while still performing well. (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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a 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 - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
