Radeon HD 3470 256MB vs Radeon HD 3690/3830

Intro

The Radeon HD 3470 256MB features a GPU clock speed of 800 MHz, and the 256 MB of DDR2 RAM is set to run at 950 MHz through a 128-bit bus. It also features 40(8x5) Stream Processors, 4 Texture Address Units, and 4 Raster Operation Units.

Compare that to the Radeon HD 3690/3830, which uses a 55 nm design. AMD has clocked the core speed at 668 MHz. The GDDR3 memory runs at a frequency of 828 MHz on this specific model. It features 320(64x5) SPUs along with 16 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 in one second. This figure is worked out by multiplying the total texture units of the card 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its 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 outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
