Compare any two graphics cards:
Radeon HD 4730 vs Radeon HD 4750
IntroThe Radeon HD 4730 uses a 55 nm design. AMD has clocked the core speed at 700 MHz. The GDDR5 RAM is set to run at a frequency of 900 MHz on this particular model. It features 640(128x5) SPUs along with 32 TAUs and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 4750, which comes with a GPU core clock speed of 730 MHz, and 512 MB of GDDR5 memory running at 800 MHz through a 128-bit bus. It also is made up of 640(128x5) SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4730 should theoretically perform a little bit faster than the Radeon HD 4750 overall. (explain)
Texel RateThe Radeon HD 4750 is a little bit (about 4%) faster with regards to texture filtering than the Radeon HD 4730. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 4750 is superior to the Radeon HD 4730, 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 maximum amount of information (counted in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video 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 most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
