Compare any two graphics cards:
GeForce 9600 GT 1GB vs GeForce GTX 550 Ti
IntroThe GeForce 9600 GT 1GB uses a 65/55 nm design. nVidia has set the core frequency at 650 MHz. The GDDR3 RAM works at a speed of 900 MHz on this particular model. It features 64 SPUs along with 32 TAUs and 16 Rasterization Operator Units.
Compare those specs to the GeForce GTX 550 Ti, which has a core clock speed of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also makes use of a 192-bit bus, and uses a 40 nm design. It is comprised of 192 SPUs, 32 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 550 Ti should theoretically be much faster than the GeForce 9600 GT 1GB overall. (explain)
Texel RateThe GeForce GTX 550 Ti will be a lot (approximately 38%) faster with regards to texture filtering than the GeForce 9600 GT 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 550 Ti is the winner, by far. (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 max amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
