Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs GeForce GT 315
IntroThe GeForce 9500 GT 1GB GDDR3 features core clock speeds of 550 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR3 RAM. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.Compare all of that to the GeForce GT 315, which makes use of a 40 nm design. nVidia has clocked the core frequency at 625 MHz. The DDR3 memory is set to run at a speed of 790 MHz on this card. It features 48 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 9500 GT 1GB GDDR3 will be 1% faster than the GeForce GT 315 overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GT 315 will be a bit (more or less 14%) more effective at anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)
Pixel RateThe GeForce GT 315 should be a little bit (about 14%) more effective at full screen anti-aliasing than the GeForce 9500 GT 1GB GDDR3, and also able to handle higher screen resolutions more effectively. (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 megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 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 can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 bandwidth is, the lower the ability to get to the max fill rate.
