GeForce GT 430 1GB vs Radeon HD 6870

Intro

The GeForce GT 430 1GB makes use of a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR3 memory works at a speed of 900 MHz on this particular card. It features 96 SPUs along with 16 TAUs and 4 Rasterization Operator Units.

Compare that to the Radeon HD 6870, which has core speeds of 900 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 memory. It features 1120 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.

GeForce GT 430 1GB 28800 MB/sec
Difference: 105600 (367%)

Texel Rate

The Radeon HD 6870 is much (about 350%) more effective at texture filtering than the GeForce GT 430 1GB. (explain)

Radeon HD 6870 50400 Mtexels/sec
GeForce GT 430 1GB 11200 Mtexels/sec
Difference: 39200 (350%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 6870 is the winner, by far. (explain)

Radeon HD 6870 28800 Mpixels/sec
GeForce GT 430 1GB 2800 Mpixels/sec
Difference: 26000 (929%)

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 information (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the interface 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 ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
