Compare any two graphics cards:
Radeon HD 3470 256MB vs Radeon R7 250
IntroThe Radeon HD 3470 256MB has core speeds of 800 MHz on the GPU, and 950 MHz on the 256 MB of DDR2 RAM. It features 40(8x5) SPUs as well as 4 Texture Address Units and 4 Rasterization Operator Units.Compare those specifications to the Radeon R7 250, which makes use of a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 memory works at a speed of 1150 MHz on this particular card. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R7 250 should theoretically be quite a bit faster than the Radeon HD 3470 256MB in general. (explain)
Texel RateThe Radeon R7 250 will be a lot (more or less 650%) better at anisotropic filtering than the Radeon HD 3470 256MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R7 250 is superior to the Radeon HD 3470 256MB, and very much so. (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 (counted in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, 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 most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
