Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs GeForce GT 315
IntroThe GeForce 8600 GT 512MB GDDR3 features a clock speed of 540 MHz and a GDDR3 memory speed of 700 MHz. It also uses a 128-bit memory bus, and makes use of a 80 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specs to the GeForce GT 315, which features a clock speed of 625 MHz and a DDR3 memory speed of 790 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is comprised of 48 SPUs, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GT 315 should theoretically be a little bit better than the GeForce 8600 GT 512MB GDDR3 in general. (explain)
Texel RateThe GeForce GT 315 should be just a bit (about 16%) better at AF than the GeForce 8600 GT 512MB GDDR3. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GT 315 is the winner, but 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 max amount of data (measured in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure 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 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 most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour 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 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 potential to reach the maximum fill rate.
