Compare any two graphics cards:
GeForce GT 315 vs GeForce GTX 560
IntroThe GeForce GT 315 uses a 40 nm design. nVidia has clocked the core speed at 625 MHz. The DDR3 RAM is set to run at a frequency of 790 MHz on this specific model. It features 48 SPUs as well as 16 Texture Address Units and 8 ROPs.
Compare those specs to the GeForce GTX 560, which has a core clock frequency of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also features a 256-bit bus, and uses a 40 nm design. It is made up of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 560 should theoretically be quite a bit better than the GeForce GT 315 overall. (explain)
Texel RateThe GeForce GTX 560 is a lot (about 354%) better at AF than the GeForce GT 315. (explain)
Pixel RateThe GeForce GTX 560 will be a lot (about 418%) faster with regards to AA than the GeForce GT 315, and also will be able to handle higher 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once 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 anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
