GeForce GT 430 1GB vs Radeon R9 M380

Intro

Compare that to the Radeon R9 M380, which comes with GPU core speed of 1000 MHz, and 4096 MB of GDDR5 memory set to run at 1500 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M380 should perform much faster than the GeForce GT 430 1GB in general. (explain)

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

Texel Rate

The Radeon R9 M380 is quite a bit (approximately 257%) more effective at anisotropic 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

The Radeon R9 M380 should be quite a bit (approximately 471%) better at FSAA than the GeForce GT 430 1GB, and able to handle higher screen resolutions without slowing down too much. (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: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result 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 number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. 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 potential to reach the max fill rate.
