Compare any two graphics cards:
GeForce 8600 GT 256MB DDR2 vs GeForce GT 340
IntroThe GeForce 8600 GT 256MB DDR2 uses a 80 nm design. nVidia has clocked the core speed at 540 MHz. The DDR2 RAM runs at a frequency of 400 MHz on this model. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.Compare all that to the GeForce GT 340, which makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 RAM works at a frequency of 850 MHz on this particular card. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 340 is 325% quicker than the GeForce 8600 GT 256MB DDR2 overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GT 340 is a lot (more or less 104%) more effective at AF than the GeForce 8600 GT 256MB DDR2. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GT 340 is the winner, though not 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 maximum amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that are 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
