Compare any two graphics cards:
Radeon HD 4830 512MB vs Radeon HD 5670
IntroThe Radeon HD 4830 512MB has a core clock speed of 575 MHz and a GDDR3 memory speed of 900 MHz. It also features a 256-bit bus, and makes use of a 55 nm design. It is made up of 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the Radeon HD 5670, which comes with a clock frequency of 775 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 400(80x5) SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Radeon HD 4830 512MB wins(Based entirely on the benchmarks listed above)When combining all game benchmark scores on this page together, the Radeon HD 4830 512MB wins overall, by 12 FPS. Please note that we do not have the results of every benchmark ever done for these cards, so the results may differ wildly in different games.
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 5670 should be 11% faster than the Radeon HD 4830 512MB overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 4830 512MB should be a bit (more or less 19%) better at texture filtering than the Radeon HD 5670. (explain)
Pixel RateThe Radeon HD 4830 512MB will be quite a bit (more or less 48%) faster with regards to AA than the Radeon HD 5670, and also will be capable of handling higher resolutions better. (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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Specifications
Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
