GeForce GT 230 vs GeForce GTX Titan Black

Intro

Compare all 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 is set to run at a speed of 1750 MHz on this particular model. It features 2880 SPUs as well as 240 Texture Address Units and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 230		65 Watts
GeForce GTX Titan Black		250 Watts
	Difference: 185 Watts (285%)

Memory Bandwidth

In theory, the GeForce GTX Titan Black is 775% quicker than the GeForce GT 230 in general, because of its higher bandwidth. (explain)

GeForce GTX Titan Black		336000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 297600 (775%)

Texel Rate

The GeForce GTX Titan Black should be 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

If using a high screen resolution is important to you, then the GeForce GTX Titan Black is superior to the GeForce GT 230, and very much so. (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 largest amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the 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 most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
