Compare any two graphics cards:
Radeon HD 4730 vs Radeon HD 6670 (OEM)
IntroThe Radeon HD 4730 has a GPU clock speed of 700 MHz, and the 512 MB of GDDR5 memory runs at 900 MHz through a 128-bit bus. It also features 640(128x5) SPUs, 32 TAUs, and 8 ROPs.Compare those specs to the Radeon HD 6670 (OEM), which makes use of a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this specific model. It features 480 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6670 (OEM) should theoretically be a small bit superior to the Radeon HD 4730 overall. (explain)
Texel RateThe Radeon HD 4730 will be a little bit (about 17%) faster with regards to AF than the Radeon HD 6670 (OEM). (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 6670 (OEM) is superior to the Radeon HD 4730, but not 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 largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
