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

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6450 (OEM) 1GB should be 9% faster than the Radeon HD 3690/3830 overall, because of its higher data rate. (explain)
Texel RateThe Radeon HD 3690/3830 is quite a bit (about 78%) faster with regards to texture filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe Radeon HD 3690/3830 should be quite a bit (approximately 256%) faster with regards to AA than the Radeon HD 6450 (OEM) 1GB, and also should be able to handle higher resolutions better. (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 data (in units of MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
