Compare any two graphics cards:
GeForce 8600 GT 256MB DDR2 vs GeForce GT 340
IntroThe GeForce 8600 GT 256MB DDR2 has a GPU core speed of 540 MHz, and the 256 MB of DDR2 RAM is set to run at 400 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 TAUs, and 8 ROPs.Compare those specifications to the GeForce GT 340, which uses a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 RAM runs at a speed of 850 MHz on this particular card. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 340 is 325% faster than the GeForce 8600 GT 256MB DDR2 overall, because of its higher data rate. (explain)
Texel RateThe GeForce GT 340 should be a lot (about 104%) faster with regards to AF than the GeForce 8600 GT 256MB DDR2. (explain)
Pixel RateIf running with a high screen resolution 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

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock 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 applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
