Compare any two graphics cards:
Radeon HD 3470 512MB vs Radeon HD 6570 (OEM) 1GB
IntroThe Radeon HD 3470 512MB has core speeds of 800 MHz on the GPU, and 950 MHz on the 512 MB of GDDR3 RAM. It features 40(8x5) SPUs along with 4 Texture Address Units and 4 Rasterization Operator Units.Compare all that to the Radeon HD 6570 (OEM) 1GB, which has GPU core speed of 650 MHz, and 1024 MB of GDDR3 RAM running at 900 MHz through a 128-bit bus. It also is made up of 480 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon HD 3470 512MB should theoretically be a small bit better than the Radeon HD 6570 (OEM) 1GB overall. (explain)
Texel RateThe Radeon HD 6570 (OEM) 1GB should be a lot (about 388%) better at texture filtering than the Radeon HD 3470 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 6570 (OEM) 1GB is a better choice, by far. (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 largest amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
