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 runs at 500 MHz through a 128-bit bus. It also 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 GPU core speed of 928 MHz, and 1024 MB of GDDR5 memory running at 1350 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 64 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 650 Ti will be 440% quicker than the GeForce 9500 GT DDR2 overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 650 Ti should be much (approximately 575%) better at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 650 Ti is a better choice, and very much so. (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 data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its 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 clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
