Radeon HD 3650 vs Radeon HD 3650 512MB
Intro
The Radeon HD 3650 makes use of a 55 nm design. AMD has clocked the core speed at 725 MHz. The GDDR4 memory is set to run at a frequency of 800 MHz on this model. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.Compare all that to the Radeon HD 3650 512MB, which comes with clock speeds of 725 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 RAM. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have the exact same memory bandwidth, so in theory they should have the same performance. (explain)
Texel Rate
Both cards have exactly the same texel fill rate, so theoretically they should be equally good at at anisotropic filtering. (explain)Pixel Rate
Both cards have exactly the 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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
