GeForce 930M vs Radeon HD 5830

Intro

Compare that to the Radeon HD 5830, which features core speeds of 800 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 1120(224x5) SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 5830 should be 789% faster than the GeForce 930M in general, because of its greater bandwidth. (explain)

Radeon HD 5830		128000 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 113600 (789%)

Texel Rate

The Radeon HD 5830 is quite a bit (approximately 101%) more effective at anisotropic filtering than the GeForce 930M. (explain)

Radeon HD 5830		44800 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 22528 (101%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 5830 is a better choice, by far. (explain)

Radeon HD 5830		12800 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 5376 (72%)

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 information (measured in megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
