GeForce GT 240 GDDR5 1GB 54400 MB/sec
Difference: 9600 (18%)

Texel Rate

The GeForce GT 240 GDDR5 1GB is a bit (approximately 14%) better at anisotropic filtering than the Radeon HD 5670. (explain)

GeForce GT 240 GDDR5 1GB 17600 Mtexels/sec
Radeon HD 5670 15500 Mtexels/sec
Difference: 2100 (14%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5670 is a better choice, and very much so. (explain)

Radeon HD 5670 6200 Mpixels/sec
GeForce GT 240 GDDR5 1GB 4400 Mpixels/sec
Difference: 1800 (41%)

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.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). 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.
