Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GTX 650 Ti
IntroThe GeForce 9500 GT DDR2 features a GPU clock speed of 550 MHz, and the 256 MB of DDR2 RAM is set to run at 500 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 TAUs, and 8 ROPs.
Compare all of that to the GeForce GTX 650 Ti, which features a core clock speed of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 768 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 650 Ti will be 440% faster than the GeForce 9500 GT DDR2 overall, because of its higher data rate. (explain)
Texel RateThe GeForce GTX 650 Ti should be a lot (more or less 575%) more effective at texture filtering than the GeForce 9500 GT DDR2. (explain)
Pixel RateThe GeForce GTX 650 Ti should be a lot (about 237%) better at FSAA than the GeForce 9500 GT DDR2, and also able to handle 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 (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
