	Difference: 27 Watts (16%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 760 should be 50% quicker than the GeForce 9800 GX2 overall, due to its greater data rate. (explain)

Geforce GTX 760		192256 MB/sec
GeForce 9800 GX2		128000 MB/sec
	Difference: 64256 (50%)

Texel Rate

The Geforce GTX 760 is much (approximately 23%) better at anisotropic filtering than the GeForce 9800 GX2. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce 9800 GX2		76800 Mtexels/sec
	Difference: 17280 (23%)

Pixel Rate

If using a high resolution is important to you, then the Geforce GTX 760 is the winner, by a large margin. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce 9800 GX2		19200 Mpixels/sec
	Difference: 12160 (63%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
