Compare any two graphics cards:
GeForce GTX 280 vs GeForce GTX 550 Ti
IntroThe GeForce GTX 280 makes use of a 65 nm design. nVidia has set the core speed at 602 MHz. The GDDR3 RAM runs at a frequency of 1107 MHz on this card. It features 240 SPUs as well as 80 Texture Address Units and 32 ROPs.
Compare those specs to the GeForce GTX 550 Ti, which has GPU clock speed of 900 MHz, and 1024 MB of GDDR5 RAM set to run at 1026 MHz through a 192-bit bus. It also features 192 Stream Processors, 32 TAUs, and 24 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 280 should in theory be a lot superior to the GeForce GTX 550 Ti overall. (explain)
Texel RateThe GeForce GTX 280 should be a lot (approximately 67%) faster with regards to anisotropic filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 550 Ti will be a little bit (approximately 12%) more effective at FSAA than the GeForce GTX 280, and will be 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 information (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 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, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number 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 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 number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 bandwidth is, the lower the potential to reach the max fill rate.
