Compare any two graphics cards:
Radeon HD 4870 512MB vs Radeon HD 5830
IntroThe Radeon HD 4870 512MB has a GPU core speed of 750 MHz, and the 512 MB of GDDR5 RAM runs at 900 MHz through a 256-bit bus. It also features 800(160x5) Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the Radeon HD 5830, which has GPU clock speed of 800 MHz, and 1024 MB of GDDR5 RAM running at 1000 MHz through a 256-bit bus. It also features 1120(224x5) Stream Processors, 56 Texture Address Units, and 16 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 5830 is 11% faster than the Radeon HD 4870 512MB in general, because of its greater data rate. (explain)
Texel RateThe Radeon HD 5830 will be a lot (approximately 49%) faster with regards to AF than the Radeon HD 4870 512MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 5830 is the winner, though not by far. (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 (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that can be applied per 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 the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
