GeForce GT 240 GDDR5 vs GeForce GTX 480

Intro

Compare those specs to the GeForce GTX 480, which features a GPU core clock speed of 700 MHz, and 1536 MB of GDDR5 memory running at 924 MHz through a 384-bit bus. It also is comprised of 480 SPUs, 60 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 240 GDDR5		70 Watts
GeForce GTX 480		250 Watts
	Difference: 180 Watts (257%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 480 should perform quite a bit faster than the GeForce GT 240 GDDR5 overall. (explain)

GeForce GTX 480		177408 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 123008 (226%)

Texel Rate

The GeForce GTX 480 is quite a bit (approximately 139%) more effective at AF than the GeForce GT 240 GDDR5. (explain)

GeForce GTX 480		42000 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 24400 (139%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 480 is the winner, and very much so. (explain)

GeForce GTX 480		33600 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 29200 (664%)

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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 can be applied per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
