GeForce GTX 280 vs GeForce GTX 550 Ti

Intro

The GeForce GTX 280 has a GPU core speed of 602 MHz, and the 1024 MB of GDDR3 memory runs at 1107 MHz through a 512-bit bus. It also is made up of 240 SPUs, 80 TAUs, and 32 ROPs.

Compare that to the GeForce GTX 550 Ti, which features GPU core speed of 900 MHz, and 1024 MB of GDDR5 memory running at 1026 MHz through a 192-bit bus. It also features 192 SPUs, 32 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 550 Ti 116 Watts
GeForce GTX 280 236 Watts
Difference: 120 Watts (103%)

Memory Bandwidth

In theory, the GeForce GTX 280 should be much faster than the GeForce GTX 550 Ti overall. (explain)

GeForce GTX 280 141696 MB/sec
GeForce GTX 550 Ti 98496 MB/sec
Difference: 43200 (44%)

Texel Rate

The GeForce GTX 280 will be quite a bit (approximately 67%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 280 48160 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 19360 (67%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 550 Ti is the winner, not by a very large margin though. (explain)

GeForce GTX 550 Ti 21600 Mpixels/sec
GeForce GTX 280 19264 Mpixels/sec
Difference: 2336 (12%)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
