Compare any two graphics cards:
Radeon HD 3650 512MB vs Radeon HD 6450 (OEM) 1GB
IntroThe Radeon HD 3650 512MB comes with a GPU core clock speed of 725 MHz, and the 512 MB of GDDR3 memory runs at 800 MHz through a 128-bit bus. It also is comprised of 120(24x5) Stream Processors, 8 TAUs, and 4 Raster Operation Units.Compare that to the Radeon HD 6450 (OEM) 1GB, which features a core clock speed of 750 MHz and a GDDR5 memory frequency of 900 MHz. It also features a 64-bit bus, and makes use of a 40 nm design. It is made up of 160 SPUs, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6450 (OEM) 1GB should be a small bit faster than the Radeon HD 3650 512MB overall. (explain)
Texel RateThe Radeon HD 6450 (OEM) 1GB should be a small bit (more or less 3%) faster with regards to anisotropic filtering than the Radeon HD 3650 512MB. (explain)
Pixel RateThe Radeon HD 6450 (OEM) 1GB should be just a bit (about 3%) faster with regards to anti-aliasing than the Radeon HD 3650 512MB, and capable of handling higher screen resolutions while still performing well. (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 maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 are applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock 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 applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
