Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GT 210
IntroThe GeForce 9500 GT DDR2 uses a 65 nm design. nVidia has clocked the core frequency at 550 MHz. The DDR2 RAM is set to run at a frequency of 500 MHz on this specific model. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.
Compare all that to the GeForce GT 210, which uses a 40 nm design. nVidia has clocked the core speed at 589 MHz. The DDR3 memory runs at a frequency of 800 MHz on this model. It features 16 SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce 9500 GT DDR2 will be 25% quicker than the GeForce GT 210 in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce 9500 GT DDR2 should be a lot (approximately 87%) more effective at texture filtering than the GeForce GT 210. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 9500 GT DDR2 is superior to the GeForce GT 210, 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the 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 figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 maximum amount of pixels the graphics card 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 Raster Operations Pipelines by the the card's clock speed. 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 output 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 ability to get to the maximum fill rate.
