GeForce GT 240 GDDR5 vs GeForce GTX 460 2GB

Intro

Compare those specs to the GeForce GTX 460 2GB, which makes use of a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 memory runs at a speed of 900 MHz on this particular card. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.

The GeForce GTX 460 2GB should be quite a bit (approximately 115%) faster with regards to anisotropic filtering than the GeForce GT 240 GDDR5. (explain)

GeForce GTX 460 2GB		37800 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 20200 (115%)

Pixel Rate

The GeForce GTX 460 2GB is quite a bit (more or less 391%) faster with regards to anti-aliasing than the GeForce GT 240 GDDR5, and also should be able to handle higher screen resolutions better. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 17200 (391%)

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 past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, 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 most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs 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 output 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 get to the maximum fill rate.
