Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GTX 650 Ti
IntroThe GeForce 9500 GT DDR2 comes with a clock speed of 550 MHz and a DDR2 memory frequency of 500 MHz. It also uses a 128-bit bus, and makes use of a 65 nm design. It features 32 SPUs, 16 TAUs, and 8 Raster Operation Units.
Compare that to the GeForce GTX 650 Ti, which features GPU clock speed of 928 MHz, and 1024 MB of GDDR5 memory running at 1350 MHz through a 128-bit bus. It also features 768 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 650 Ti is 440% faster than the GeForce 9500 GT DDR2 overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 650 Ti is a lot (about 575%) faster with regards to AF 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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
