Compare any two graphics cards:
GeForce 9400 GT 256MB vs GeForce GTX 650 Ti 2GB
IntroThe GeForce 9400 GT 256MB makes use of a 65 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR2 RAM is set to run at a frequency of 400 MHz on this specific card. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.Compare all that to the GeForce GTX 650 Ti 2GB, which features a core clock frequency of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It features 768 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 650 Ti 2GB should theoretically be much better than the GeForce 9400 GT 256MB overall. (explain)
Texel RateThe GeForce GTX 650 Ti 2GB will be much (more or less 1250%) faster with regards to anisotropic filtering than the GeForce 9400 GT 256MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti 2GB is superior to the GeForce 9400 GT 256MB, 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
