GeForce GT 240 GDDR5 vs GeForce GTX 550 Ti

Intro

Compare all of that to the GeForce GTX 550 Ti, which comes with core speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 RAM. It features 192 SPUs as well as 32 Texture Address Units and 24 Rasterization Operator Units.

GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 44096 (81%)

Texel Rate

The GeForce GTX 550 Ti is quite a bit (approximately 64%) more effective at texture filtering than the GeForce GT 240 GDDR5. (explain)

GeForce GTX 550 Ti		28800 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 11200 (64%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 550 Ti is a better choice, by a large margin. (explain)

GeForce GTX 550 Ti		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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
