Compare any two graphics cards:
Radeon HD 3650 256MB vs Radeon HD 6450 (OEM)
IntroThe Radeon HD 3650 256MB has a clock frequency of 725 MHz and a DDR2 memory frequency of 800 MHz. It also features a 128-bit bus, and makes use of a 55 nm design. It features 120(24x5) SPUs, 8 TAUs, and 4 Raster Operation Units.Compare those specifications to the Radeon HD 6450 (OEM), which comes with a clock speed of 625 MHz and a GDDR3 memory speed of 800 MHz. It also uses a 64-bit bus, and makes use of a 40 nm design. It is comprised of 160 SPUs, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 3650 256MB will be 100% faster than the Radeon HD 6450 (OEM) in general, because of its higher bandwidth. (explain)
Texel RateThe Radeon HD 3650 256MB is a little bit (more or less 16%) better at anisotropic filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 3650 256MB is a better choice, not by a very large margin though. (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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card 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 per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
