Compare any two graphics cards:
GeForce 8800 GTX vs GeForce GTX 650 Ti
IntroThe GeForce 8800 GTX uses a 90 nm design. nVidia has set the core speed at 575 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this particular model. It features 128 SPUs as well as 64 TAUs and 24 Rasterization Operator Units.Compare all that to the GeForce GTX 650 Ti, which features a GPU core clock speed of 928 MHz, and 1024 MB of GDDR5 RAM running at 1350 MHz through a 128-bit bus. It also is made up of 768 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe GeForce GTX 650 Ti should be a lot (more or less 61%) better at AF than the GeForce 8800 GTX. (explain)
Pixel RateThe GeForce GTX 650 Ti should be a small bit (more or less 8%) better at FSAA than the GeForce 8800 GTX, and also should be able to handle higher screen 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many 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.
