Compare any two graphics cards:
GeForce GTX 260 vs GeForce GTX 550 Ti
IntroThe GeForce GTX 260 makes use of a 65 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 RAM works at a speed of 999 MHz on this model. It features 192 SPUs as well as 64 Texture Address Units and 28 ROPs.
Compare those specifications to the GeForce GTX 550 Ti, which comes with GPU clock speed of 900 MHz, and 1024 MB of GDDR5 memory set to run at 1026 MHz through a 192-bit bus. It also features 192 Stream Processors, 32 Texture Address Units, and 24 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 260 is 14% quicker than the GeForce GTX 550 Ti in general, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 260 will be quite a bit (more or less 28%) more effective at AF than the GeForce GTX 550 Ti. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 550 Ti is a better choice, by far. (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 largest amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
