Compare any two graphics cards:
GeForce GTX 280 vs GeForce GTX 550 Ti
IntroThe GeForce GTX 280 features a clock speed of 602 MHz and a GDDR3 memory frequency of 1107 MHz. It also features a 512-bit bus, and makes use of a 65 nm design. It is comprised of 240 SPUs, 80 Texture Address Units, and 32 ROPs.
Compare those specs to the GeForce GTX 550 Ti, which uses a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 memory is set to run at a frequency of 1026 MHz on this particular model. It features 192 SPUs along with 32 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 280 should theoretically be quite a bit better than the GeForce GTX 550 Ti overall. (explain)
Texel RateThe GeForce GTX 280 should be quite a bit (more or less 67%) more effective at anisotropic filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 550 Ti is a little bit (more or less 12%) more effective at FSAA than the GeForce GTX 280, and also capable of handling higher resolutions while still performing well. (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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core 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 fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
