Compare any two graphics cards:
Radeon HD 5750 1GB vs Radeon HD 6870
IntroThe Radeon HD 5750 1GB uses a 40 nm design. AMD has clocked the core speed at 700 MHz. The GDDR5 RAM runs at a frequency of 1150 MHz on this specific model. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 Rasterization Operator Units.Compare all that to the Radeon HD 6870, which features GPU clock speed of 900 MHz, and 1024 MB of GDDR5 RAM running at 1050 MHz through a 256-bit bus. It also is made up of 1120 Stream Processors, 56 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6870 should be a lot faster than the Radeon HD 5750 1GB overall. (explain)
Texel RateThe Radeon HD 6870 should be much (about 100%) better at texture filtering than the Radeon HD 5750 1GB. (explain)
Pixel RateThe Radeon HD 6870 will be much (about 157%) better at FSAA than the Radeon HD 5750 1GB, and able to handle higher screen resolutions without losing too much performance. (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 max amount of information (counted in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling 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 the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
