GeForce GT 230 vs GeForce GTX Titan Black

Intro

Compare that to the GeForce GTX Titan Black, which uses a 28 nm design. nVidia has clocked the core frequency at 889 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this card. It features 2880 SPUs along with 240 Texture Address Units and 48 ROPs.

GeForce GT 230		38400 MB/sec
	Difference: 297600 (775%)

Texel Rate

The GeForce GTX Titan Black is much (more or less 2325%) better at anisotropic filtering than the GeForce GT 230. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 204560 (2325%)

Pixel Rate

The GeForce GTX Titan Black should be much (about 870%) more effective at AA than the GeForce GT 230, and will be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 38272 (870%)

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 max amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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