Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 580 3GB
IntroThe GeForce GTX 550 Ti uses a 40 nm design. nVidia has set the core speed at 900 MHz. The GDDR5 RAM is set to run at a frequency of 1026 MHz on this specific model. It features 192 SPUs along with 32 TAUs and 24 Rasterization Operator Units.
Compare those specs to the GeForce GTX 580 3GB, which features a clock speed of 772 MHz and a GDDR5 memory frequency of 1002 MHz. It also makes use of a 384-bit bus, and makes use of a 40 nm design. It features 512 SPUs, 64 TAUs, and 48 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 580 3GB should theoretically be a lot superior to the GeForce GTX 550 Ti in general. (explain)
Texel RateThe GeForce GTX 580 3GB should be much (approximately 72%) faster with regards to AF than the GeForce GTX 550 Ti. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 580 3GB is superior to the GeForce GTX 550 Ti, by a large margin. (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 maximum amount of data (counted in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 of the card by the core 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 per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
