GeForce GT 230 vs GeForce GTX 780 Ti

Intro

Compare that to the GeForce GTX 780 Ti, which features GPU core speed of 875 MHz, and 3072 MB of GDDR5 memory running at 1750 MHz through a 384-bit bus. It also is made up of 2880 SPUs, 240 Texture Address Units, and 48 ROPs.

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

Texel Rate

The GeForce GTX 780 Ti will be quite a bit (more or less 2286%) faster with regards to texture filtering than the GeForce GT 230. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 201200 (2286%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 780 Ti is the winner, by far. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 37600 (855%)

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 data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
