Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GT 210
IntroThe GeForce 9500 GT DDR2 has a clock frequency of 550 MHz and a DDR2 memory speed of 500 MHz. It also uses a 128-bit memory bus, and uses a 65 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.
Compare those specifications to the GeForce GT 210, which makes use of a 40 nm design. nVidia has set the core frequency at 589 MHz. The DDR3 RAM works at a frequency of 800 MHz on this specific card. It features 16 SPUs along with 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce 9500 GT DDR2, in theory, should perform quite a bit faster than the GeForce GT 210 overall. (explain)
Texel RateThe GeForce 9500 GT DDR2 should be a lot (more or less 87%) better at AF than the GeForce GT 210. (explain)
Pixel RateThe GeForce 9500 GT DDR2 will be much (approximately 87%) faster with regards to AA than the GeForce GT 210, and also will be capable of handling higher screen resolutions without slowing down too much. (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 maximum amount of information (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
