GeForce 8400 GS 512MB vs Radeon HD 5830

Intro

The GeForce 8400 GS 512MB comes with core clock speeds of 650 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Compare all of that to the Radeon HD 5830, which features GPU clock speed of 800 MHz, and 1024 MB of GDDR5 memory set to run at 1000 MHz through a 256-bit bus. It also is made up of 1120(224x5) Stream Processors, 56 Texture Address Units, and 16 ROPs.

Radeon HD 5830 128000 MB/sec
GeForce 8400 GS 512MB 6400 MB/sec
Difference: 121600 (1900%)

Texel Rate

The Radeon HD 5830 will be much (about 762%) better at anisotropic filtering than the GeForce 8400 GS 512MB. (explain)

Radeon HD 5830 44800 Mtexels/sec
GeForce 8400 GS 512MB 5200 Mtexels/sec
Difference: 39600 (762%)

Pixel Rate

The Radeon HD 5830 will be quite a bit (approximately 392%) better at FSAA than the GeForce 8400 GS 512MB, and also should be able to handle higher resolutions better. (explain)

Radeon HD 5830 12800 Mpixels/sec
GeForce 8400 GS 512MB 2600 Mpixels/sec
Difference: 10200 (392%)

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 max amount of information (measured in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount 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 could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
