Radeon HD 3470 512MB vs Radeon HD 6950 2GB

Intro

The Radeon HD 3470 512MB makes use of a 55 nm design. AMD has set the core speed at 800 MHz. The GDDR3 RAM works at a frequency of 950 MHz on this model. It features 40(8x5) SPUs as well as 4 TAUs and 4 ROPs.

Compare all of that to the Radeon HD 6950 2GB, which has a GPU core clock speed of 800 MHz, and 2048 MB of GDDR5 RAM running at 1250 MHz through a 256-bit bus. It also features 1408 Stream Processors, 88 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon HD 6950 2GB should be much faster than the Radeon HD 3470 512MB overall. (explain)

Radeon HD 6950 2GB 160000 MB/sec
Radeon HD 3470 512MB 30400 MB/sec
Difference: 129600 (426%)

Texel Rate

The Radeon HD 6950 2GB should be quite a bit (more or less 2100%) better at AF than the Radeon HD 3470 512MB. (explain)

Radeon HD 6950 2GB 70400 Mtexels/sec
Radeon HD 3470 512MB 3200 Mtexels/sec
Difference: 67200 (2100%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 6950 2GB is a better choice, by far. (explain)

Radeon HD 6950 2GB 25600 Mpixels/sec
Radeon HD 3470 512MB 3200 Mpixels/sec
Difference: 22400 (700%)

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 information (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
