Compare any two graphics cards:
GeForce GT 315 vs GeForce GT 430 1GB
IntroThe GeForce GT 315 uses a 40 nm design. nVidia has clocked the core speed at 625 MHz. The DDR3 RAM runs at a speed of 790 MHz on this specific card. It features 48 SPUs along with 16 TAUs and 8 ROPs.Compare all that to the GeForce GT 430 1GB, which features a clock frequency of 700 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 96 SPUs, 16 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 430 1GB should perform a bit faster than the GeForce GT 315 overall. (explain)
Texel RateThe GeForce GT 430 1GB should be a bit (more or less 12%) better at anisotropic filtering than the GeForce GT 315. (explain)
Pixel RateThe GeForce GT 315 is a lot (about 79%) more effective at full screen anti-aliasing than the GeForce GT 430 1GB, and 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 maximum amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type 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 AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card 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 number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
