Compare any two graphics cards:
Radeon HD 4730 vs Radeon HD 6750 1GB
IntroThe Radeon HD 4730 has a GPU core clock speed of 700 MHz, and the 512 MB of GDDR5 RAM runs at 900 MHz through a 128-bit bus. It also is comprised of 640(128x5) Stream Processors, 32 TAUs, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 6750 1GB, which comes with core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 720 SPUs along with 36 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6750 1GB should be 11% faster than the Radeon HD 4730 in general, because of its higher data rate. (explain)
Texel RateThe Radeon HD 6750 1GB will be just a bit (more or less 17%) faster with regards to AF than the Radeon HD 4730. (explain)
Pixel RateThe Radeon HD 6750 1GB will be a lot (approximately 107%) better at FSAA than the Radeon HD 4730, and also should be able to handle higher resolutions without slowing down too much. (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 largest amount of information (in units of MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the 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 that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
