Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GTX 465
IntroThe GeForce 9500 GT DDR2 uses a 65 nm design. nVidia has set the core frequency at 550 MHz. The DDR2 RAM runs at a frequency of 500 MHz on this card. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.Compare those specifications to the GeForce GTX 465, which uses a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 memory is set to run at a frequency of 802 MHz on this specific model. It features 352 SPUs as well as 44 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 465 should theoretically be much faster than the GeForce 9500 GT DDR2 overall. (explain)
Texel RateThe GeForce GTX 465 is a lot (more or less 204%) more effective at AF than the GeForce 9500 GT DDR2. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 465 is a better choice, by a large margin. (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 max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of 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.
