Radeon HD 3470 256MB vs Radeon HD 6950

Intro

The Radeon HD 3470 256MB features a clock frequency of 800 MHz and a DDR2 memory frequency of 950 MHz. It also makes use of a 128-bit memory bus, and makes use of a 55 nm design. It is made up of 40(8x5) SPUs, 4 TAUs, and 4 Raster Operation Units.

Compare all that to the Radeon HD 6950, which uses a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory works at a frequency of 1250 MHz on this specific model. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
