Compare any two graphics cards:
Radeon HD 4350 vs Radeon HD 6670 (OEM)
IntroThe Radeon HD 4350 comes with a GPU clock speed of 575 MHz, and the 512 MB of DDR2 memory is set to run at 500 MHz through a 64-bit bus. It also is made up of 80(16x5) SPUs, 8 TAUs, and 4 Raster Operation Units.Compare all that to the Radeon HD 6670 (OEM), which has GPU core speed of 800 MHz, and 512 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6670 (OEM) should in theory be much better than the Radeon HD 4350 in general. (explain)
Texel RateThe Radeon HD 6670 (OEM) should be quite a bit (approximately 317%) faster with regards to texture filtering than the Radeon HD 4350. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 6670 (OEM) is a better choice, and very much so. (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 max amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 processed per second. This number 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 a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
