Compare any two graphics cards:
Radeon HD 3650 vs Radeon HD 4670 512MB
IntroThe Radeon HD 3650 comes with a GPU core speed of 725 MHz, and the 1024 MB of GDDR4 RAM runs at 800 MHz through a 128-bit bus. It also is made up of 120(24x5) Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.Compare all of that to the Radeon HD 4670 512MB, which makes use of a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 RAM is set to run at a frequency of 1000 MHz on this model. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 4670 512MB should be much faster than the Radeon HD 3650 in general. (explain)
Texel RateThe Radeon HD 4670 512MB should be much (about 314%) better at texture filtering than the Radeon HD 3650. (explain)
Pixel RateThe Radeon HD 4670 512MB is a lot (approximately 107%) more effective at full screen anti-aliasing than the Radeon HD 3650, and also able to handle higher resolutions more effectively. (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 (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per 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 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 the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
