Compare any two graphics cards:
GeForce 8800 GTS (G92) vs GeForce GTX 650
IntroThe GeForce 8800 GTS (G92) comes with a core clock frequency of 650 MHz and a GDDR3 memory frequency of 970 MHz. It also features a 256-bit bus, and makes use of a 65 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.
Compare those specifications to the GeForce GTX 650, which has clock speeds of 1058 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 memory. It features 384 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 650 will be 29% quicker than the GeForce 8800 GTS (G92) in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce 8800 GTS (G92) is quite a bit (more or less 23%) better at texture filtering than the GeForce GTX 650. (explain)
Pixel RateThe GeForce GTX 650 is much (more or less 63%) faster with regards to full screen anti-aliasing than the GeForce 8800 GTS (G92), and also should be capable of handling higher screen resolutions while still performing well. (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 largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, 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 AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
