Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GT 210
IntroThe GeForce 9500 GT DDR2 has a GPU core speed of 550 MHz, and the 256 MB of DDR2 memory runs at 500 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 TAUs, and 8 ROPs.
Compare those specs to the GeForce GT 210, which features a GPU core clock speed of 589 MHz, and 512 MB of DDR3 memory running at 800 MHz through a 64-bit bus. It also is made up of 16 Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce 9500 GT DDR2 will be 25% quicker than the GeForce GT 210 overall, because of its higher data rate. (explain)
Texel RateThe GeForce 9500 GT DDR2 will be a lot (about 87%) faster with regards to texture filtering than the GeForce GT 210. (explain)
Pixel RateThe GeForce 9500 GT DDR2 should be much (about 87%) more effective at FSAA than the GeForce GT 210, and also able to handle higher resolutions without losing too much performance. (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: Bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are 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 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 in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
