Radeon HD 3470 256MB vs Radeon HD 3470 512MB

Intro

The Radeon HD 3470 256MB makes use of a 55 nm design. AMD has clocked the core frequency at 800 MHz. The DDR2 RAM runs at a speed of 950 MHz on this particular card. It features 40(8x5) SPUs along with 4 Texture Address Units and 4 ROPs.

Compare that to the Radeon HD 3470 512MB, which makes use of a 55 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR3 RAM runs at a speed of 950 MHz on this card. It features 40(8x5) SPUs as well as 4 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

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

Pixel Rate

Both cards have the exact same pixel rate, so in theory they should be equally good at at full screen anti-aliasing, 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 maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 are applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 amount 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 ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
