Compare any two graphics cards:
Radeon HD 3470 512MB vs Radeon R7 240
IntroThe Radeon HD 3470 512MB comes with core clock speeds of 800 MHz on the GPU, and 950 MHz on the 512 MB of GDDR3 RAM. It features 40(8x5) SPUs as well as 4 TAUs and 4 ROPs.Compare those specs to the Radeon R7 240, which comes with core speeds of 730 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 3470 512MB should in theory be a bit better than the Radeon R7 240 in general. (explain)
Texel RateThe Radeon R7 240 will be a lot (more or less 356%) faster with regards to anisotropic filtering than the Radeon HD 3470 512MB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R7 240 is the winner, 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 data (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. 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 also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
