Compare any two graphics cards:
Radeon HD 3650 vs Radeon R9 280X
IntroThe Radeon HD 3650 has clock speeds of 725 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR4 RAM. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 ROPs.Compare those specs to the Radeon R9 280X, which uses a 28 nm design. AMD has clocked the core frequency at 850 MHz. The GDDR5 memory works at a frequency of 1500 MHz on this particular model. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 280X should in theory be quite a bit better than the Radeon HD 3650 overall. (explain)
Texel RateThe Radeon R9 280X is a lot (about 1776%) faster with regards to texture filtering than the Radeon HD 3650. (explain)
Pixel RateThe Radeon R9 280X should be much (about 838%) faster with regards to anti-aliasing than the Radeon HD 3650, and will be capable of handling 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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
