Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M380 should perform quite a bit faster than the GeForce GT 430 1GB overall. (explain)

Radeon R9 M380		96000 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 67200 (233%)

Texel Rate

The Radeon R9 M380 should be a lot (about 257%) faster with regards to texture filtering than the GeForce GT 430 1GB. (explain)

Radeon R9 M380		40000 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 28800 (257%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M380 is superior to the GeForce GT 430 1GB, and very much so. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 13200 (471%)

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 max amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
