GeForce 8400 GS 512MB vs Radeon HD 5450

Intro

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

Compare that to the Radeon HD 5450, which comes with a core clock frequency of 650 MHz and a DDR3 memory speed of 800 MHz. It also features a 64-bit memory bus, and uses a 40 nm design. It is made up of 80(16x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5450 19 Watts
GeForce 8400 GS 512MB 40 Watts
Difference: 21 Watts (111%)

Memory Bandwidth

Performance-wise, the Radeon HD 5450 should in theory be much better than the GeForce 8400 GS 512MB in general. (explain)

Radeon HD 5450 12800 MB/sec
GeForce 8400 GS 512MB 6400 MB/sec
Difference: 6400 (100%)

Texel Rate

Both cards have the exact same texel fill rate, so theoretically they should perform equally good at at AF. (explain)

Pixel Rate

Both cards have the exact same pixel rate, so theoretically they should be equally good at at FSAA, and be able to handle the same screen resolutions. (explain)

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 largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units 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 rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
