GeForce GTX 650 Ti 2GB 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 frequency at 889 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this model. It features 2880 SPUs as well as 240 TAUs and 48 Rasterization Operator Units.

GeForce GTX 650 Ti 2GB		110 Watts
GeForce GTX Titan Black		250 Watts
	Difference: 140 Watts (127%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan Black will be 289% faster than the GeForce GTX 650 Ti 2GB in general, because of its greater bandwidth. (explain)

GeForce GTX Titan Black		336000 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 249600 (289%)

Texel Rate

The GeForce GTX Titan Black should be quite a bit (approximately 259%) more effective at anisotropic filtering than the GeForce GTX 650 Ti 2GB. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
	Difference: 153968 (259%)

Pixel Rate

The GeForce GTX Titan Black is a lot (more or less 187%) faster with regards to FSAA than the GeForce GTX 650 Ti 2GB, and also will be able to handle higher screen resolutions better. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 27824 (187%)

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 maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
