Compare any two graphics cards:
GeForce GTX 560 Ti vs GeForce GTX 650
IntroThe GeForce GTX 560 Ti comes with a GPU core speed of 822 MHz, and the 1024 MB of GDDR5 memory runs at 1002 MHz through a 256-bit bus. It also is made up of 384 Stream Processors, 64 Texture Address Units, and 32 ROPs.
Compare all that to the GeForce GTX 650, which uses a 28 nm design. nVidia has set the core frequency at 1058 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this model. It features 384 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 560 Ti should be a lot faster than the GeForce GTX 650 in general. (explain)
Texel RateThe GeForce GTX 560 Ti should be a lot (approximately 55%) better at texture filtering than the GeForce GTX 650. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 560 Ti is the winner, and very much so. (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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 get to the max fill rate.
