Compare any two graphics cards:
Radeon HD 3470 256MB vs Radeon HD 6750
IntroThe Radeon HD 3470 256MB features a clock frequency of 800 MHz and a DDR2 memory frequency of 950 MHz. It also uses a 128-bit bus, and uses a 55 nm design. It features 40(8x5) SPUs, 4 Texture Address Units, and 4 ROPs.Compare all that to the Radeon HD 6750, which features clock speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. It features 720 SPUs along with 36 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon HD 6750 should in theory be much superior to the Radeon HD 3470 256MB overall. (explain)
Texel RateThe Radeon HD 6750 should be much (about 716%) better at anisotropic filtering than the Radeon HD 3470 256MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 6750 is a better choice, by a large margin. (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 data (counted in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
