Compare any two graphics cards:
GeForce GT 450 (OEM) vs Radeon HD 3470 256MB
IntroThe GeForce GT 450 (OEM) uses a 40 nm design. nVidia has set the core speed at 790 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this model. It features 144 SPUs along with 24 TAUs and 24 ROPs.Compare all of that to the Radeon HD 3470 256MB, which uses a 55 nm design. AMD has set the core speed at 800 MHz. The DDR2 memory is set to run at a frequency of 950 MHz on this specific card. It features 40(8x5) SPUs as well as 4 Texture Address Units and 4 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the GeForce GT 450 (OEM) will be 216% faster than the Radeon HD 3470 256MB in general, because of its greater data rate. (explain)
Texel RateThe GeForce GT 450 (OEM) is a lot (about 493%) more effective at anisotropic filtering than the Radeon HD 3470 256MB. (explain)
Pixel RateThe GeForce GT 450 (OEM) will be quite a bit (about 493%) better at AA than the Radeon HD 3470 256MB, and should be able to handle higher screen resolutions while still performing well. (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 (measured in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card 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 applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs 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 - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
