Compare any two graphics cards:
GeForce 8500 GT vs GeForce 9500 GT DDR2
IntroThe GeForce 8500 GT makes use of a 80 nm design. nVidia has set the core frequency at 450 MHz. The DDR2 RAM is set to run at a frequency of 400 MHz on this particular model. It features 16 SPUs along with 8 Texture Address Units and 4 ROPs.Compare those specs to the GeForce 9500 GT DDR2, which uses a 65 nm design. nVidia has set the core frequency at 550 MHz. The DDR2 memory is set to run at a speed of 500 MHz on this model. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 9500 GT DDR2 should perform quite a bit faster than the GeForce 8500 GT in general. (explain)
Texel RateThe GeForce 9500 GT DDR2 is much (approximately 144%) better at anisotropic filtering than the GeForce 8500 GT. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 9500 GT DDR2 is a better choice, 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must 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 AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
