Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GT 310
IntroThe GeForce 8600 GT 512MB DDR2 features clock speeds of 540 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 32 SPUs as well as 16 TAUs and 8 ROPs.Compare all that to the GeForce GT 310, which has a GPU core clock speed of 589 MHz, and 512 MB of DDR2 memory set to run at 1000 MHz through a 64-bit bus. It also is comprised of 16 Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GT 310 should in theory be quite a bit better than the GeForce 8600 GT 512MB DDR2 in general. (explain)
Texel RateThe GeForce 8600 GT 512MB DDR2 should be much (about 83%) more effective at anisotropic filtering than the GeForce GT 310. (explain)
Pixel RateThe GeForce 8600 GT 512MB DDR2 should be quite a bit (approximately 83%) better at anti-aliasing than the GeForce GT 310, and should be able to handle higher screen resolutions without losing too much performance. (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 max amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core clock 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 in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
