Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750 1GB		86 Watts
Geforce GTX 770		230 Watts
	Difference: 144 Watts (167%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 770 should be 251% faster than the Radeon HD 6750 1GB overall, because of its greater bandwidth. (explain)

Geforce GTX 770		224384 MB/sec
Radeon HD 6750 1GB		64000 MB/sec
	Difference: 160384 (251%)

Texel Rate

The Geforce GTX 770 will be a lot (more or less 413%) better at anisotropic filtering than the Radeon HD 6750 1GB. (explain)

Geforce GTX 770		133888 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 107788 (413%)

Pixel Rate

The Geforce GTX 770 is much (approximately 189%) more effective at full screen anti-aliasing than the Radeon HD 6750 1GB, and also able to handle higher screen resolutions without losing too much performance. (explain)

Geforce GTX 770		33472 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 21872 (189%)

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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
