Compare any two graphics cards:
Radeon HD 3650 vs Radeon HD 6450 (OEM) 1GB
IntroThe Radeon HD 3650 has a core clock frequency of 725 MHz and a GDDR4 memory frequency of 800 MHz. It also uses a 128-bit bus, and makes use of a 55 nm design. It features 120(24x5) SPUs, 8 TAUs, and 4 ROPs.Compare all that to the Radeon HD 6450 (OEM) 1GB, which features GPU core speed of 750 MHz, and 1024 MB of GDDR5 RAM running at 900 MHz through a 64-bit bus. It also is comprised of 160 Stream Processors, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6450 (OEM) 1GB should be 13% quicker than the Radeon HD 3650 overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 6450 (OEM) 1GB should be a little bit (more or less 3%) better at AF than the Radeon HD 3650. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 6450 (OEM) 1GB is a better choice, though only just barely. (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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 can be processed per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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 is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
