Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GTX 650 Ti
IntroThe GeForce 9500 GT DDR2 features 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 is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.
Compare those specifications to the GeForce GTX 650 Ti, which comes with core speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 memory. It features 768 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 650 Ti should in theory be much better than the GeForce 9500 GT DDR2 overall. (explain)
Texel RateThe GeForce GTX 650 Ti is quite a bit (about 575%) better at AF than the GeForce 9500 GT DDR2. (explain)
Pixel RateThe GeForce GTX 650 Ti should be much (approximately 237%) faster with regards to FSAA than the GeForce 9500 GT DDR2, and should be capable of handling higher screen 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 maximum amount of information (in units of MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock 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 applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its 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 - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
