Compare any two graphics cards:
Radeon HD 3690/3830 vs Radeon HD 6450 (OEM) 1GB
IntroThe Radeon HD 3690/3830 uses a 55 nm design. AMD has set the core frequency at 668 MHz. The GDDR3 memory is set to run at a frequency of 828 MHz on this specific model. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 Rasterization Operator Units.Compare all of that to the Radeon HD 6450 (OEM) 1GB, which has a clock frequency of 750 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 64-bit bus, and uses a 40 nm design. It is made up of 160 SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6450 (OEM) 1GB should in theory be a bit superior to the Radeon HD 3690/3830 in general. (explain)
Texel RateThe Radeon HD 3690/3830 should be much (about 78%) better at texture filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe Radeon HD 3690/3830 should be a lot (approximately 256%) better at anti-aliasing than the Radeon HD 6450 (OEM) 1GB, and also should be able to handle higher screen resolutions more effectively. (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 max amount of information (measured in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of 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 clock speed of the chip. The better the texel rate, the better the 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 most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
