Compare any two graphics cards:
GeForce GT 310 vs GeForce GTX 660 Ti
IntroThe GeForce GT 310 uses a 40 nm design. nVidia has set the core speed at 589 MHz. The DDR2 RAM works at a frequency of 1000 MHz on this particular card. It features 16 SPUs as well as 8 Texture Address Units and 4 ROPs.
Compare all that to the GeForce GTX 660 Ti, which uses a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 memory runs at a frequency of 1500 MHz on this particular model. It features 1344 SPUs as well as 112 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 660 Ti should in theory be much better than the GeForce GT 310 in general. (explain)
Texel RateThe GeForce GTX 660 Ti should be quite a bit (approximately 2075%) faster with regards to texture filtering than the GeForce GT 310. (explain)
Pixel RateThe GeForce GTX 660 Ti is quite a bit (about 832%) faster with regards to full screen anti-aliasing than the GeForce GT 310, and capable of handling higher screen resolutions better. (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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. 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 also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
