Compare any two graphics cards:
Radeon HD 3650 256MB vs Radeon R7 250X 2GB
IntroThe Radeon HD 3650 256MB makes use of a 55 nm design. AMD has clocked the core speed at 725 MHz. The DDR2 RAM works at a frequency of 800 MHz on this particular card. It features 120(24x5) SPUs as well as 8 TAUs and 4 ROPs.Compare all of that to the Radeon R7 250X 2GB, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R7 250X 2GB should be 181% quicker than the Radeon HD 3650 256MB in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon R7 250X 2GB will be quite a bit (approximately 590%) more effective at AF than the Radeon HD 3650 256MB. (explain)
Pixel RateThe Radeon R7 250X 2GB is much (approximately 452%) more effective at FSAA than the Radeon HD 3650 256MB, and also will be capable of handling higher resolutions without losing too much performance. (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 data (in units of megabytes per second) that can be transported past the external memory interface in a second. The number is 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 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
