GeForce GTX 880M vs Radeon HD 5830

Intro

The GeForce GTX 880M comes with a core clock speed of 954 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Compare all that to the Radeon HD 5830, which features a core clock frequency of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It is made up of 1120(224x5) SPUs, 56 TAUs, 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 the exact same bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce GTX 880M should be much (about 173%) more effective 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 running with a high screen resolution is important to you, then the GeForce GTX 880M is superior to the Radeon HD 5830, 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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better 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 one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
