GeForce GTX 980 Ti vs GeForce GTX Titan Black

Intro

Compare all of that to the GeForce GTX Titan Black, which makes use of a 28 nm design. nVidia has set the core speed at 889 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this card. It features 2880 SPUs along with 240 Texture Address Units and 48 ROPs.

Memory Bandwidth

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

Texel Rate

The GeForce GTX Titan Black should be a lot (approximately 21%) better at texture filtering 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 (approximately 125%) more effective at AA than the GeForce GTX Titan Black, and will be able to handle higher resolutions without losing too much performance. (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 maximum amount of data (counted in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the 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 are processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
