Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GTX 260
IntroThe GeForce 8600 GT 512MB DDR2 features core clock speeds of 540 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 memory. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare all that to the GeForce GTX 260, which features a core clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also features a 448-bit bus, and uses a 65 nm design. It is made up of 192 SPUs, 64 TAUs, and 28 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 260 is 774% faster than the GeForce 8600 GT 512MB DDR2 overall, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 260 is a lot (approximately 327%) faster with regards to anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 260 is the winner, 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 maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
