Compare any two graphics cards:
Radeon HD 3470 512MB vs Radeon HD 3650
IntroThe Radeon HD 3470 512MB comes with a core clock speed of 800 MHz and a GDDR3 memory speed of 950 MHz. It also makes use of a 128-bit bus, and uses a 55 nm design. It is made up of 40(8x5) SPUs, 4 Texture Address Units, and 4 Raster Operation Units.Compare those specifications to the Radeon HD 3650, which has core speeds of 725 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR4 RAM. It features 120(24x5) SPUs along with 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 3470 512MB should theoretically perform a little bit faster than the Radeon HD 3650 overall. (explain)
Texel RateThe Radeon HD 3650 will be a lot (approximately 81%) better at AF than the Radeon HD 3470 512MB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 3470 512MB is superior to the Radeon HD 3650, but only just. (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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out 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 drawing the pixels (image) on the screen. The actual pixel output rate is also dependant 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.
