Compare any two graphics cards:
Radeon HD 5750 1GB vs Radeon HD 7770
IntroThe Radeon HD 5750 1GB uses a 40 nm design. AMD has set the core speed at 700 MHz. The GDDR5 memory is set to run at a frequency of 1150 MHz on this particular model. It features 720(144x5) SPUs as well as 36 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 7770, which makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5750 1GB should in theory be a bit faster than the Radeon HD 7770 overall. (explain)
Texel RateThe Radeon HD 7770 is quite a bit (more or less 59%) more effective at anisotropic filtering than the Radeon HD 5750 1GB. (explain)
Pixel RateThe Radeon HD 7770 will be much (more or less 43%) better at FSAA than the Radeon HD 5750 1GB, and should be able to handle higher resolutions better. (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 maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 applied per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 memory bandwidth is, the lower the potential to reach the max fill rate.
