GeForce GTX 880M vs Radeon HD 5830

Intro

The GeForce GTX 880M has a GPU core clock speed of 954 MHz, and the 4096 MB of GDDR5 memory runs at 1000 MHz through a 256-bit bus. It also features 1536 Stream Processors, 128 Texture Address Units, and 32 ROPs.

Compare that to the Radeon HD 5830, which comes with GPU core speed of 800 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 256-bit bus. It also features 1120(224x5) SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 880M 130 Watts
Radeon HD 5830 175 Watts
Difference: 45 Watts (35%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce GTX 880M is quite a bit (approximately 173%) better at anisotropic filtering than the Radeon HD 5830. (explain)

GeForce GTX 880M 122112 Mtexels/sec
Radeon HD 5830 44800 Mtexels/sec
Difference: 77312 (173%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 880M is the winner, by far. (explain)

GeForce GTX 880M 30528 Mpixels/sec
Radeon HD 5830 12800 Mpixels/sec
Difference: 17728 (139%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 are applied in one second. This number 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 card will be at handling 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 can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
