Compare any two graphics cards:
Radeon HD 4830 1GB vs Radeon HD 6670 (OEM)
IntroThe Radeon HD 4830 1GB comes with a core clock speed of 575 MHz and a GDDR4 memory frequency of 900 MHz. It also features a 256-bit memory bus, and makes use of a 55 nm design. It features 640(128x5) SPUs, 32 TAUs, and 16 ROPs.Compare all of that to the Radeon HD 6670 (OEM), which features GPU clock speed of 800 MHz, and 512 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6670 (OEM) should perform a small bit faster than the Radeon HD 4830 1GB in general. (explain)
Texel RateThe Radeon HD 6670 (OEM) should be just a bit (about 4%) more effective at anisotropic filtering than the Radeon HD 4830 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 4830 1GB is a better choice, by a large margin. (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 information (counted in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 per second. This figure is worked out by multiplying the total number of 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 in one second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number 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 outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
