Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 260 Core 216 should theoretically perform just a bit faster than the Radeon R9 M380 in general. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 15888 (17%)

Texel Rate

The GeForce GTX 260 Core 216 is a bit (approximately 4%) faster with regards to anisotropic filtering than the Radeon R9 M380. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 1472 (4%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 260 Core 216 is the winner, not by a very large margin though. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 128 (1%)

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 (measured in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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