Compare any two graphics cards:
Radeon HD 5830 vs Radeon R9 270X
IntroThe Radeon HD 5830 comes with a GPU clock speed of 800 MHz, and the 1024 MB of GDDR5 memory runs at 1000 MHz through a 256-bit bus. It also is made up of 1120(224x5) SPUs, 56 TAUs, and 16 Raster Operation Units.Compare those specs to the Radeon R9 270X, which comes with GPU core speed of 1000 MHz, and 2048 MB of GDDR5 memory running at 1400 MHz through a 256-bit bus. It also features 1280 Stream Processors, 80 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 270X, in theory, should perform a lot faster than the Radeon HD 5830 in general. (explain)
Texel RateThe Radeon R9 270X will be much (about 79%) faster with regards to anisotropic filtering than the Radeon HD 5830. (explain)
Pixel RateThe Radeon R9 270X should be a lot (more or less 150%) faster with regards to FSAA than the Radeon HD 5830, and should be 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 maximum amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
