Compare any two graphics cards:
GeForce GTX 480 vs GeForce GTX 650
IntroThe GeForce GTX 480 uses a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR5 RAM works at a speed of 924 MHz on this particular model. It features 480 SPUs as well as 60 TAUs and 48 ROPs.
Compare those specifications to the GeForce GTX 650, which has GPU clock speed of 1058 MHz, and 2048 MB of GDDR5 RAM running at 1250 MHz through a 128-bit bus. It also is comprised of 384 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 480 is 122% quicker than the GeForce GTX 650 in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 480 should be much (about 24%) better at anisotropic filtering than the GeForce GTX 650. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 480 is a better choice, by far. (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 information (measured in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 applied in one second. This is calculated by multiplying the total number of texture units of the card 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 applied per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
