Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 5830 will be 700% quicker than the Radeon R5 M230 in general, because of its greater data rate. (explain)

Radeon HD 5830		128000 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 112000 (700%)

Texel Rate

The Radeon HD 5830 is much (approximately 187%) more effective at texture filtering than the Radeon R5 M230. (explain)

Radeon HD 5830		44800 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 29200 (187%)

Pixel Rate

The Radeon HD 5830 will be much (about 310%) faster with regards to FSAA than the Radeon R5 M230, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon HD 5830		12800 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 9680 (310%)

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 max amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
