Compare any two graphics cards:
Radeon HD 3850 256MB vs Radeon HD 6750 1GB
IntroThe Radeon HD 3850 256MB uses a 55 nm design. AMD has set the core speed at 668 MHz. The GDDR3 memory runs at a frequency of 828 MHz on this specific card. It features 320(64x5) SPUs along with 16 TAUs and 16 Rasterization Operator Units.Compare that to the Radeon HD 6750 1GB, which comes with GPU core speed of 725 MHz, and 1024 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 720 SPUs, 36 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6750 1GB should be quite a bit faster than the Radeon HD 3850 256MB overall. (explain)
Texel RateThe Radeon HD 6750 1GB will be a lot (more or less 144%) better at AF than the Radeon HD 3850 256MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 6750 1GB is a better choice, but it probably won't make a huge difference. (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 maximum amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 in one second. This figure is worked out by multiplying the total texture units 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 maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
