Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs GeForce GT 315
IntroThe GeForce 9500 GT 512MB GDDR3 comes with a clock speed of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also makes use of a 128-bit bus, and makes use of a 55 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specifications to the GeForce GT 315, which has a GPU core clock speed of 625 MHz, and 512 MB of DDR3 RAM running at 790 MHz through a 128-bit bus. It also is made up of 48 Stream Processors, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 9500 GT 512MB GDDR3 is 1% faster than the GeForce GT 315 overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce GT 315 will be a bit (approximately 14%) better at anisotropic filtering than the GeForce 9500 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: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
