Compare any two graphics cards:
Radeon HD 4730 vs Radeon HD 4850 2GB
IntroThe Radeon HD 4730 features 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 those specifications to the Radeon HD 4850 2GB, which has a clock speed of 625 MHz and a GDDR4 memory speed of 993 MHz. It also uses a 256-bit bus, and makes use of a 55 nm design. It 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 2GB, in theory, should perform a little bit faster than the Radeon HD 4730 in general. (explain)
Texel RateThe Radeon HD 4850 2GB should be just a bit (approximately 12%) faster with regards to anisotropic filtering than the Radeon HD 4730. (explain)
Pixel RateThe Radeon HD 4850 2GB should be much (approximately 79%) more effective at anti-aliasing than the Radeon HD 4730, and also will be capable of handling 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 data (measured in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 number of texture map elements (texels) that are applied per second. This figure is calculated 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number 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 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.
