Compare any two graphics cards:
GeForce 8600 GT 256MB DDR2 vs GeForce GT 310
IntroThe GeForce 8600 GT 256MB DDR2 makes use of a 80 nm design. nVidia has set the core speed at 540 MHz. The DDR2 RAM runs at a speed of 400 MHz on this card. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specs to the GeForce GT 310, which has a clock frequency of 589 MHz and a DDR2 memory speed of 1000 MHz. It also uses a 64-bit bus, and makes use of a 40 nm design. It is comprised of 16 SPUs, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 310 is 25% faster than the GeForce 8600 GT 256MB DDR2 overall, because of its greater data rate. (explain)
Texel RateThe GeForce 8600 GT 256MB DDR2 will be a lot (about 83%) more effective at anisotropic filtering than the GeForce GT 310. (explain)
Pixel RateThe GeForce 8600 GT 256MB DDR2 is much (about 83%) faster with regards to FSAA than the GeForce GT 310, and also will be able to handle higher screen resolutions while still performing well. (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 (measured in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
