Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs GeForce GT 315
IntroThe GeForce 9500 GT 512MB GDDR3 features a GPU core clock speed of 550 MHz, and the 512 MB of GDDR3 memory is set to run at 800 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 Texture Address Units, and 8 ROPs.Compare those specifications to the GeForce GT 315, which comes with a clock frequency of 625 MHz and a DDR3 memory frequency of 790 MHz. It also makes use of a 128-bit memory 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 BandwidthThe GeForce 9500 GT 512MB GDDR3 should theoretically be just a bit faster than the GeForce GT 315 overall. (explain)
Texel RateThe GeForce GT 315 is a small bit (about 14%) faster with regards to anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GT 315 is superior to the GeForce 9500 GT 512MB GDDR3, though only just barely. (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 (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result 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 higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. 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 output 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 get to the max fill rate.
