Compare any two graphics cards:
GeForce 8300 GS (OEM) vs GeForce GTX 660 Ti
IntroThe GeForce 8300 GS (OEM) has core speeds of 450 MHz on the GPU, and 400 MHz on the 128 MB of DDR2 RAM. It features 8 SPUs as well as 4 TAUs and 2 Rasterization Operator Units.
Compare those specifications to the GeForce GTX 660 Ti, which makes use of a 28 nm design. nVidia has clocked the core frequency at 915 MHz. The GDDR5 memory runs at a frequency of 1500 MHz on this specific card. It features 1344 SPUs as well as 112 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 660 Ti should in theory be a lot better than the GeForce 8300 GS (OEM) overall. (explain)
Texel RateThe GeForce GTX 660 Ti should be much (approximately 5593%) faster with regards to texture filtering than the GeForce 8300 GS (OEM). (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 660 Ti is superior to the GeForce 8300 GS (OEM), 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 (measured in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card 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 in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. 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 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 get to the maximum fill rate.
