Compare any two graphics cards:
Radeon HD 4730 vs Radeon HD 4850 1GB
IntroThe Radeon HD 4730 has core speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR5 memory. It features 640(128x5) SPUs as well as 32 TAUs and 8 ROPs.Compare that to the Radeon HD 4850 1GB, which features a GPU core clock speed of 625 MHz, and 1024 MB of GDDR4 memory running at 993 MHz through a 256-bit bus. It also is comprised of 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4850 1GB should theoretically perform just a bit faster than the Radeon HD 4730 in general. (explain)
Texel RateThe Radeon HD 4850 1GB should be a bit (more or less 12%) better at anisotropic filtering than the Radeon HD 4730. (explain)
Pixel RateThe Radeon HD 4850 1GB is quite a bit (more or less 79%) better at FSAA than the Radeon HD 4730, and will be able to handle higher resolutions while still performing well. (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 largest amount of information (in units of MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core 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 processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
