Compare any two graphics cards:
Radeon HD 6770 1GB vs Radeon R7 250X 2GB
IntroThe Radeon HD 6770 1GB features a GPU core speed of 900 MHz, and the 1024 MB of GDDR5 memory runs at 1050 MHz through a 128-bit bus. It also is made up of 800 SPUs, 40 TAUs, and 16 ROPs.Compare that to the Radeon R7 250X 2GB, which features core clock speeds of 1000 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon R7 250X 2GB should be a little bit faster than the Radeon HD 6770 1GB overall. (explain)
Texel RateThe Radeon R7 250X 2GB should be a bit (more or less 11%) more effective at texture filtering than the Radeon HD 6770 1GB. (explain)
Pixel RateThe Radeon R7 250X 2GB will be just a bit (about 11%) faster with regards to full screen anti-aliasing than the Radeon HD 6770 1GB, and should be able to handle 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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported past the external memory interface within a 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 higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
