Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 650
IntroThe GeForce GTX 550 Ti makes use of a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 RAM runs at a speed of 1026 MHz on this card. It features 192 SPUs along with 32 Texture Address Units and 24 Rasterization Operator Units.
Compare those specs to the GeForce GTX 650, which has clock speeds of 1058 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 memory. It features 384 SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 550 Ti should theoretically be a lot better than the GeForce GTX 650 in general. (explain)
Texel RateThe GeForce GTX 650 will be a small bit (approximately 18%) better at texture filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 550 Ti will be a lot (more or less 28%) better at AA than the GeForce GTX 650, and will be able to handle higher screen resolutions better. (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 MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units 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 in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
