GeForce 8400 GS 512MB vs Radeon HD 5570

Intro

The GeForce 8400 GS 512MB uses a 80 nm design. nVidia has set the core speed at 650 MHz. The DDR2 RAM works at a frequency of 400 MHz on this card. It features 16 SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Compare those specs to the Radeon HD 5570, which features a GPU core clock speed of 650 MHz, and 512 MB of DDR3 memory set to run at 900 MHz through a 128-bit bus. It also is comprised of 400(80x5) Stream Processors, 20 TAUs, and 8 ROPs.

Radeon HD 5570 13000 Mtexels/sec
GeForce 8400 GS 512MB 5200 Mtexels/sec
Difference: 7800 (150%)

Pixel Rate

The Radeon HD 5570 should be much (more or less 100%) more effective at FSAA than the GeForce 8400 GS 512MB, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 5570 5200 Mpixels/sec
GeForce 8400 GS 512MB 2600 Mpixels/sec
Difference: 2600 (100%)

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 data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
