Compare any two graphics cards:
Radeon HD 4770 vs Radeon HD 5670
IntroThe Radeon HD 4770 uses a 40 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR5 RAM works at a speed of 800 MHz on this specific card. It features 640(128x5) SPUs along with 32 TAUs and 16 ROPs.Compare those specifications to the Radeon HD 5670, which has a clock frequency of 775 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It features 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5670 is 25% quicker than the Radeon HD 4770 overall, because of its higher bandwidth. (explain)
Texel RateThe Radeon HD 4770 should be a lot (approximately 55%) faster with regards to anisotropic filtering than the Radeon HD 5670. (explain)
Pixel RateThe Radeon HD 4770 will be quite a bit (more or less 94%) better at full screen anti-aliasing than the Radeon HD 5670, and will 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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
