Compare any two graphics cards:
GeForce 9600 GT 512MB vs GeForce GTX 550 Ti
IntroThe GeForce 9600 GT 512MB uses a 65/55 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this specific model. It features 64 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.
Compare all that to the GeForce GTX 550 Ti, which comes with core speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs as well as 32 TAUs and 24 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 550 Ti should in theory be much superior to the GeForce 9600 GT 512MB in general. (explain)
Texel RateThe GeForce GTX 550 Ti should be a lot (more or less 38%) better at anisotropic filtering than the GeForce 9600 GT 512MB. (explain)
Pixel RateThe GeForce GTX 550 Ti is quite a bit (more or less 108%) better at FSAA than the GeForce 9600 GT 512MB, and 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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
