Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GTX 650 Ti
IntroThe GeForce 9500 GT DDR2 comes with a clock frequency of 550 MHz and a DDR2 memory speed of 500 MHz. It also uses a 128-bit memory bus, and makes use of a 65 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.
Compare all of that to the GeForce GTX 650 Ti, which has a core clock speed of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 768 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 650 Ti should theoretically be much better than the GeForce 9500 GT DDR2 in general. (explain)
Texel RateThe GeForce GTX 650 Ti is quite a bit (approximately 575%) more effective at AF than the GeForce 9500 GT DDR2. (explain)
Pixel RateThe GeForce GTX 650 Ti should be much (about 237%) better at anti-aliasing than the GeForce 9500 GT DDR2, and will be capable of handling higher 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 (counted in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
