Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GT 210
IntroThe GeForce 9500 GT DDR2 comes with a clock frequency of 550 MHz and a DDR2 memory speed of 500 MHz. It also makes use of a 128-bit memory bus, and makes use of a 65 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 ROPs.
Compare all of that to the GeForce GT 210, which uses a 40 nm design. nVidia has set the core speed at 589 MHz. The DDR3 RAM runs at a frequency of 800 MHz on this specific card. It features 16 SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce 9500 GT DDR2 should theoretically be much superior to the GeForce GT 210 in general. (explain)
Texel RateThe GeForce 9500 GT DDR2 is a lot (more or less 87%) more effective at texture filtering than the GeForce GT 210. (explain)
Pixel RateThe GeForce 9500 GT DDR2 will be a lot (approximately 87%) better at full screen anti-aliasing than the GeForce GT 210, and also will be capable of handling higher resolutions more effectively. (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 (counted in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
