Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 780 Ti should be a lot faster than the Radeon R9 M380 overall. (explain)

GeForce GTX 780 Ti		336000 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 240000 (250%)

Texel Rate

The GeForce GTX 780 Ti should be much (about 425%) more effective at AF than the Radeon R9 M380. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 170000 (425%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 780 Ti is superior to the Radeon R9 M380, by a large margin. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 26000 (163%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock 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 fill rate is also dependant on lots of 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.
