GeForce 930M vs Radeon HD 5830

Intro

Compare all of that to the Radeon HD 5830, which features a core clock frequency of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It features 1120(224x5) SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 5830 is 789% faster than the GeForce 930M overall, because of its greater data rate. (explain)

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

Texel Rate

The Radeon HD 5830 will be a lot (about 101%) better 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 lots of anti-aliasing is important to you, then the Radeon HD 5830 is the winner, and very much so. (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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the 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 maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
