Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 650
IntroThe GeForce GTX 550 Ti comes with a GPU core speed of 900 MHz, and the 1024 MB of GDDR5 RAM runs at 1026 MHz through a 192-bit bus. It also is made up of 192 SPUs, 32 Texture Address Units, and 24 ROPs.
Compare those specifications 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 speed of 1250 MHz on this specific model. It features 384 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 550 Ti should be a lot faster than the GeForce GTX 650 in general. (explain)
Texel RateThe GeForce GTX 650 should be a little bit (about 18%) more effective at AF than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 550 Ti is quite a bit (about 28%) better at FSAA than the GeForce GTX 650, and also should be capable of handling higher screen resolutions without slowing down too much. (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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
