Radeon HD 3470 512MB vs Radeon HD 3650 512MB
Intro
The Radeon HD 3470 512MB has a core clock frequency of 800 MHz and a GDDR3 memory speed of 950 MHz. It also uses a 128-bit memory bus, and makes use of a 55 nm design. It is comprised of 40(8x5) SPUs, 4 TAUs, and 4 ROPs.Compare those specifications to the Radeon HD 3650 512MB, which has GPU clock speed of 725 MHz, and 512 MB of GDDR3 memory running at 800 MHz through a 128-bit bus. It also features 120(24x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units 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 in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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 potential to reach the maximum fill rate.
