	Difference: 121600 (224%)

Texel Rate

The Radeon HD 6970 is quite a bit (more or less 380%) faster with regards to texture filtering than the GeForce GT 240 GDDR5. (explain)

Radeon HD 6970		84480 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 66880 (380%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 6970 is a better choice, by far. (explain)

Radeon HD 6970		28160 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 23760 (540%)

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 data (in units of megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the 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 maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
