Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs GeForce GTX 480
IntroThe GeForce 8600 GT 256MB GDDR3 makes use of a 80 nm design. nVidia has set the core speed at 540 MHz. The GDDR3 RAM is set to run at a speed of 700 MHz on this particular card. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare those specifications to the GeForce GTX 480, which has GPU core speed of 700 MHz, and 1536 MB of GDDR5 memory set to run at 924 MHz through a 384-bit bus. It also is comprised of 480 Stream Processors, 60 Texture Address Units, and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 480 should in theory perform much faster than the GeForce 8600 GT 256MB GDDR3 in general. (explain)
Texel RateThe GeForce GTX 480 will be a lot (approximately 386%) faster with regards to AF than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateThe GeForce GTX 480 will be much (more or less 678%) more effective at FSAA than the GeForce 8600 GT 256MB GDDR3, and should be capable of handling higher resolutions better. (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 data (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
