Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 760		170 Watts
Radeon HD 6950 2GB		200 Watts
	Difference: 30 Watts (18%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 760 should be 20% faster than the Radeon HD 6950 2GB overall, because of its higher data rate. (explain)

Geforce GTX 760		192256 MB/sec
Radeon HD 6950 2GB		160000 MB/sec
	Difference: 32256 (20%)

Texel Rate

The Geforce GTX 760 is quite a bit (about 34%) faster with regards to texture filtering than the Radeon HD 6950 2GB. (explain)

Geforce GTX 760		94080 Mtexels/sec
Radeon HD 6950 2GB		70400 Mtexels/sec
	Difference: 23680 (34%)

Pixel Rate

The Geforce GTX 760 is much (more or less 23%) more effective at anti-aliasing than the Radeon HD 6950 2GB, and will be capable of handling higher screen resolutions without slowing down too much. (explain)

Geforce GTX 760		31360 Mpixels/sec
Radeon HD 6950 2GB		25600 Mpixels/sec
	Difference: 5760 (23%)

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 moved over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 memory bandwidth is, the lower the ability to reach the max fill rate.
