Compare any two graphics cards:
Radeon HD 3850 1GB vs Radeon HD 6750
IntroThe Radeon HD 3850 1GB has a clock speed of 668 MHz and a GDDR3 memory frequency of 828 MHz. It also makes use of a 256-bit bus, and uses a 55 nm design. It is comprised of 320(64x5) SPUs, 16 TAUs, and 16 Raster Operation Units.Compare all of that to the Radeon HD 6750, which has GPU clock speed of 725 MHz, and 512 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is comprised of 720 SPUs, 36 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6750 should in theory be a lot better than the Radeon HD 3850 1GB overall. (explain)
Texel RateThe Radeon HD 6750 should be a lot (about 144%) faster with regards to anisotropic filtering than the Radeon HD 3850 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 6750 is superior to the Radeon HD 3850 1GB, though only just barely. (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 (measured in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it must 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 AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, 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 maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
