Compare any two graphics cards:
Radeon HD 3850 256MB vs Radeon HD 6750 1GB
IntroThe Radeon HD 3850 256MB makes use of a 55 nm design. AMD has set the core frequency at 668 MHz. The GDDR3 memory works at a speed of 828 MHz on this card. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 6750 1GB, which makes use of a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this particular card. It features 720 SPUs along with 36 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6750 1GB should theoretically perform a lot faster than the Radeon HD 3850 256MB in general. (explain)
Texel RateThe Radeon HD 6750 1GB is much (about 144%) better at anisotropic filtering than the Radeon HD 3850 256MB. (explain)
Pixel RateThe Radeon HD 6750 1GB is a small bit (about 9%) more effective at anti-aliasing than the Radeon HD 3850 256MB, and will be capable of handling higher resolutions more effectively. (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 data (counted in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on 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 bandwidth is, the lower the ability to get to the max fill rate.
