GeForce GTX 260 Core 216 vs GeForce GTX 550 Ti

Intro

The GeForce GTX 260 Core 216 makes use of a 65 nm design. nVidia has set the core speed at 576 MHz. The GDDR3 RAM runs at a frequency of 999 MHz on this specific model. It features 216 SPUs as well as 72 Texture Address Units and 28 Rasterization Operator Units.

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 runs at a speed of 1026 MHz on this specific model. It features 192 SPUs along with 32 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 550 Ti 116 Watts
GeForce GTX 260 Core 216 202 Watts
Difference: 86 Watts (74%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 Core 216 will be 14% quicker than the GeForce GTX 550 Ti overall, because of its higher data rate. (explain)

GeForce GTX 260 Core 216 111888 MB/sec
GeForce GTX 550 Ti 98496 MB/sec
Difference: 13392 (14%)

Texel Rate

The GeForce GTX 260 Core 216 is much (more or less 44%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 260 Core 216 41472 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 12672 (44%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 550 Ti is the winner, and very much so. (explain)

GeForce GTX 550 Ti 21600 Mpixels/sec
GeForce GTX 260 Core 216 16128 Mpixels/sec
Difference: 5472 (34%)

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 maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
