Compare any two graphics cards:
Radeon HD 3650 512MB vs Radeon R7 250
IntroThe Radeon HD 3650 512MB makes use of a 55 nm design. AMD has clocked the core speed at 725 MHz. The GDDR3 RAM runs at a speed of 800 MHz on this particular card. It features 120(24x5) SPUs along with 8 Texture Address Units and 4 ROPs.Compare that to the Radeon R7 250, which uses a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 memory is set to run at a frequency of 1150 MHz on this particular model. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R7 250 will be 188% quicker than the Radeon HD 3650 512MB in general, due to its greater bandwidth. (explain)
Texel RateThe Radeon R7 250 should be a lot (approximately 314%) faster with regards to AF than the Radeon HD 3650 512MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R7 250 is a better choice, by a large margin. (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 (in units of MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
