Compare any two graphics cards:
GeForce GTX 560 Ti 448 vs GeForce GTX 650
IntroThe GeForce GTX 560 Ti 448 makes use of a 40 nm design. nVidia has set the core speed at 732 MHz. The GDDR5 memory runs at a frequency of 900 MHz on this specific model. It features 448 SPUs along with 56 TAUs and 40 ROPs.
Compare all that to the GeForce GTX 650, which comes with core speeds of 1058 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs along with 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 560 Ti 448 should perform a lot faster than the GeForce GTX 650 in general. (explain)
Texel RateThe GeForce GTX 560 Ti 448 is a lot (about 21%) more effective at anisotropic filtering than the GeForce GTX 650. (explain)
Pixel RateThe GeForce GTX 560 Ti 448 is much (approximately 73%) more effective at AA than the GeForce GTX 650, and also should be capable of handling higher 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 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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
