Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon HD 6790 will be 56% quicker than the GeForce GTX 460 in general, due to its higher data rate. (explain)

Radeon HD 6790		134400 MB/sec
GeForce GTX 460		86400 MB/sec
	Difference: 48000 (56%)

Texel Rate

The GeForce GTX 460 will be a little bit (more or less 13%) faster with regards to texture filtering than the Radeon HD 6790. (explain)

GeForce GTX 460		37800 Mtexels/sec
Radeon HD 6790		33600 Mtexels/sec
	Difference: 4200 (13%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 460 is a better choice, by far. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon HD 6790		13440 Mpixels/sec
	Difference: 2760 (21%)

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 data (measured in megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling 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 its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
