Compare any two graphics cards:
Radeon HD 5750 1GB vs Radeon HD 5770
IntroThe Radeon HD 5750 1GB comes with a GPU clock speed of 700 MHz, and the 1024 MB of GDDR5 memory runs at 1150 MHz through a 128-bit bus. It also is comprised of 720(144x5) Stream Processors, 36 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 5770, which has GPU core speed of 850 MHz, and 1024 MB of GDDR5 RAM set to run at 1200 MHz through a 128-bit bus. It also features 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 5770 should in theory be a bit superior to the Radeon HD 5750 1GB in general. (explain)
Texel RateThe Radeon HD 5770 should be much (about 35%) faster with regards to anisotropic filtering than the Radeon HD 5750 1GB. (explain)
Pixel RateThe Radeon HD 5770 is quite a bit (approximately 21%) more effective at anti-aliasing than the Radeon HD 5750 1GB, and will be capable of handling higher screen resolutions without slowing down too much. (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 (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
