Compare any two graphics cards:
GeForce 8300 GS (OEM) vs GeForce GTX 660 Ti
IntroThe GeForce 8300 GS (OEM) makes use of a 80 nm design. nVidia has clocked the core frequency at 450 MHz. The DDR2 memory works at a frequency of 400 MHz on this particular model. It features 8 SPUs along with 4 TAUs and 2 ROPs.
Compare all of that to the GeForce GTX 660 Ti, which has core speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1344 SPUs as well as 112 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 660 Ti, in theory, should perform quite a bit faster than the GeForce 8300 GS (OEM) overall. (explain)
Texel RateThe GeForce GTX 660 Ti should be a lot (more or less 5593%) more effective at anisotropic filtering than the GeForce 8300 GS (OEM). (explain)
Pixel RateThe GeForce GTX 660 Ti will be quite a bit (about 2340%) more effective at FSAA than the GeForce 8300 GS (OEM), and also should be able to handle higher screen resolutions more effectively. (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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per 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 applied in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on 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 potential to get to the maximum fill rate.
