Compare any two graphics cards:
GeForce 8300 GS (OEM) vs GeForce GTX 660 Ti
IntroThe GeForce 8300 GS (OEM) uses a 80 nm design. nVidia has clocked the core frequency at 450 MHz. The DDR2 memory is set to run at a frequency of 400 MHz on this specific card. It features 8 SPUs as well as 4 Texture Address Units and 2 Rasterization Operator Units.
Compare those specs to the GeForce GTX 660 Ti, which comes with a core clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 192-bit memory bus, and makes use of a 28 nm design. It features 1344 SPUs, 112 TAUs, and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 660 Ti should perform a lot faster than the GeForce 8300 GS (OEM) in general. (explain)
Texel RateThe GeForce GTX 660 Ti should be quite a bit (approximately 5593%) more effective at AF than the GeForce 8300 GS (OEM). (explain)
Pixel RateThe GeForce GTX 660 Ti is quite a bit (about 2340%) more effective at full screen anti-aliasing than the GeForce 8300 GS (OEM), and able to handle higher resolutions better. (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 maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out 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 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core 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 applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
