Compare any two graphics cards:
Radeon HD 6450 (OEM) 1GB vs Radeon HD 6670 (OEM) 1GB
IntroThe Radeon HD 6450 (OEM) 1GB comes with a GPU core clock speed of 750 MHz, and the 1024 MB of GDDR5 RAM runs at 900 MHz through a 64-bit bus. It also features 160 Stream Processors, 8 TAUs, and 4 Raster Operation Units.Compare those specs to the Radeon HD 6670 (OEM) 1GB, which comes with a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is made up of 480 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6670 (OEM) 1GB should in theory perform quite a bit faster than the Radeon HD 6450 (OEM) 1GB overall. (explain)
Texel RateThe Radeon HD 6670 (OEM) 1GB should be much (more or less 220%) better at texture filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 6670 (OEM) 1GB is superior to the Radeon HD 6450 (OEM) 1GB, by far. (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 (in units of MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units by the core 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 in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
