Compare any two graphics cards:
Radeon HD 3470 512MB vs Radeon HD 6570 (OEM) 1GB
IntroThe Radeon HD 3470 512MB comes with a GPU core clock speed of 800 MHz, and the 512 MB of GDDR3 memory runs at 950 MHz through a 128-bit bus. It also features 40(8x5) Stream Processors, 4 TAUs, and 4 Raster Operation Units.Compare those specs to the Radeon HD 6570 (OEM) 1GB, which makes use of a 40 nm design. AMD has clocked the core speed at 650 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this specific model. It features 480 SPUs along with 24 Texture Address Units and 8 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon HD 3470 512MB is 6% faster than the Radeon HD 6570 (OEM) 1GB in general, due to its greater data rate. (explain)
Texel RateThe Radeon HD 6570 (OEM) 1GB should be quite a bit (more or less 388%) faster with regards to AF than the Radeon HD 3470 512MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 6570 (OEM) 1GB is superior to the Radeon HD 3470 512MB, 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 information (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's 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 amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
