Compare any two graphics cards:
Radeon HD 4750 vs Radeon HD 6750
IntroThe Radeon HD 4750 makes use of a 40 nm design. AMD has clocked the core speed at 730 MHz. The GDDR5 RAM is set to run at a speed of 800 MHz on this model. It features 640(128x5) SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.Compare all of that to the Radeon HD 6750, which uses a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this specific card. It features 720 SPUs as well as 36 TAUs and 16 Rasterization Operator Units.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6750 should in theory perform much faster than the Radeon HD 4750 in general. (explain)
Texel RateThe Radeon HD 6750 should be just a bit (more or less 12%) more effective at AF than the Radeon HD 4750. (explain)
Pixel RateThe Radeon HD 4750 is a bit (about 1%) more effective at anti-aliasing than the Radeon HD 6750, and also capable of handling 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 largest amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
