Compare any two graphics cards:
GeForce 9600 GT 512MB vs GeForce GTX 550 Ti
IntroThe GeForce 9600 GT 512MB features a core clock frequency of 650 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 256-bit memory bus, and uses a 65/55 nm design. It is comprised of 64 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.
Compare those specs to the GeForce GTX 550 Ti, which makes use of a 40 nm design. nVidia has set the core speed at 900 MHz. The GDDR5 RAM works at a frequency of 1026 MHz on this particular card. It features 192 SPUs as well as 32 TAUs and 24 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 550 Ti should in theory be a lot superior to the GeForce 9600 GT 512MB in general. (explain)
Texel RateThe GeForce GTX 550 Ti will be much (more or less 38%) better at anisotropic filtering than the GeForce 9600 GT 512MB. (explain)
Pixel RateThe GeForce GTX 550 Ti is much (approximately 108%) faster with regards to full screen anti-aliasing than the GeForce 9600 GT 512MB, and capable of handling 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.
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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 potential to reach the maximum fill rate.
