Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GTX 460 (OEM) should theoretically perform quite a bit faster than the GeForce GTX 460 in general. (explain)

GeForce GTX 460 (OEM)		108800 MB/sec
GeForce GTX 460		86400 MB/sec
	Difference: 22400 (26%)

Texel Rate

The GeForce GTX 460 is a small bit (approximately 4%) faster with regards to AF than the GeForce GTX 460 (OEM). (explain)

GeForce GTX 460		37800 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 1400 (4%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 460 (OEM) is superior to the GeForce GTX 460, and very much so. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
GeForce GTX 460		16200 Mpixels/sec
	Difference: 4600 (28%)

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 largest amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 number of texture map elements (texels) that can be applied per second. This number 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 video 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 maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
