GeForce GT 430 1GB vs Radeon R9 M380

Intro

Compare that to the Radeon R9 M380, which features clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M380 should be 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 much (about 257%) better 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

If running with lots of anti-aliasing is important to you, then the Radeon R9 M380 is superior to the GeForce GT 430 1GB, by a large margin. (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 maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 get to the max fill rate.
