Compare any two graphics cards:
GeForce GTX 560 vs GeForce GTX 650
IntroThe GeForce GTX 560 features a core clock speed of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It is made up of 336 SPUs, 56 TAUs, and 32 ROPs.
Compare that to the GeForce GTX 650, which uses a 28 nm design. nVidia has clocked the core frequency at 1058 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this particular card. It features 384 SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 560 should theoretically perform quite a bit faster than the GeForce GTX 650 overall. (explain)
Texel RateThe GeForce GTX 560 will be quite a bit (more or less 34%) more effective at texture filtering than the GeForce GTX 650. (explain)
Pixel RateThe GeForce GTX 560 will be much (about 53%) more effective at AA than the GeForce GTX 650, and will 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 max amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 figure is calculated by multiplying the total number of texture units of the card 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 applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
