Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GTX 650 Ti
IntroThe GeForce 9500 GT DDR2 makes use of a 65 nm design. nVidia has set the core speed at 550 MHz. The DDR2 RAM works at a frequency of 500 MHz on this specific model. It features 32 SPUs as well as 16 TAUs and 8 ROPs.
Compare all of that to the GeForce GTX 650 Ti, which makes use of a 28 nm design. nVidia has set the core speed at 928 MHz. The GDDR5 memory runs at a speed of 1350 MHz on this particular card. It features 768 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 650 Ti should theoretically perform much faster than the GeForce 9500 GT DDR2 in general. (explain)
Texel RateThe GeForce GTX 650 Ti is quite a bit (more or less 575%) faster with regards to anisotropic filtering than the GeForce 9500 GT DDR2. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 650 Ti is superior to the GeForce 9500 GT DDR2, by a large margin. (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 largest amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 are applied in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
