Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GT 210
IntroThe GeForce 9500 GT DDR2 has clock speeds of 550 MHz on the GPU, and 500 MHz on the 256 MB of DDR2 RAM. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.
Compare those specifications to the GeForce GT 210, which has 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 comprised of 16 Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce 9500 GT DDR2 should be a lot faster than the GeForce GT 210 in general. (explain)
Texel RateThe GeForce 9500 GT DDR2 should be quite a bit (approximately 87%) faster with regards to AF 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 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.
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 largest amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
