GeForce GT 240 GDDR5 vs GeForce GTX 460 SE

Intro

Compare all of that to the GeForce GTX 460 SE, which makes use of a 40 nm design. nVidia has set the core speed at 650 MHz. The GDDR5 memory is set to run at a frequency of 850 MHz on this specific model. It features 288 SPUs along with 48 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 240 GDDR5		70 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 80 Watts (114%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE is 100% faster than the GeForce GT 240 GDDR5 in general, because of its higher bandwidth. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 54400 (100%)

Texel Rate

The GeForce GTX 460 SE is much (more or less 77%) better at texture filtering than the GeForce GT 240 GDDR5. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 13600 (77%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is a better choice, by far. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 16400 (373%)

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 (measured in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics 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 that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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 max fill rate.
