Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs GeForce 9500 GT 512MB GDDR3
IntroThe GeForce 8600 GT 256MB GDDR3 has core clock speeds of 540 MHz on the GPU, and 700 MHz on the 256 MB of GDDR3 RAM. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.Compare those specs to the GeForce 9500 GT 512MB GDDR3, which comes with core clock speeds of 550 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 memory. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 9500 GT 512MB GDDR3 should perform a bit faster than the GeForce 8600 GT 256MB GDDR3 in general. (explain)
Texel RateThe GeForce 9500 GT 512MB GDDR3 will be a bit (approximately 2%) better at anisotropic filtering than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateThe GeForce 9500 GT 512MB GDDR3 will be a small bit (approximately 2%) more effective at full screen anti-aliasing than the GeForce 8600 GT 256MB GDDR3, and also should be able to handle higher resolutions more effectively. (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 maximum amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated 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 it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
