GeForce GT 230 vs GeForce GTX 660 Ti

Intro

Compare that to the GeForce GTX 660 Ti, which features a GPU core clock speed of 915 MHz, and 2048 MB of GDDR5 RAM set to run at 1500 MHz through a 192-bit bus. It also is made up of 1344 Stream Processors, 112 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 230		65 Watts
GeForce GTX 660 Ti		150 Watts
	Difference: 85 Watts (131%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 660 Ti should in theory be quite a bit superior to the GeForce GT 230 overall. (explain)

GeForce GTX 660 Ti		144000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 105600 (275%)

Texel Rate

The GeForce GTX 660 Ti should be quite a bit (more or less 1065%) better at texture filtering than the GeForce GT 230. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 93680 (1065%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 660 Ti is a better choice, and very much so. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 17560 (399%)

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 (counted in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
