GeForce GTX 550 Ti vs GeForce GTX 870M

Intro

The GeForce GTX 550 Ti has a clock frequency of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also features a 192-bit bus, and uses a 40 nm design. It is made up of 192 SPUs, 32 Texture Address Units, and 24 ROPs.

Compare all that to the GeForce GTX 870M, which features core clock speeds of 941 MHz on the GPU, and 1000 MHz on the 3072 MB of GDDR5 memory. It features 1344 SPUs as well as 112 Texture Address Units and 24 Rasterization Operator Units.

As far as performance goes, the GeForce GTX 550 Ti should in theory be just a bit superior to the GeForce GTX 870M in general. (explain)

GeForce GTX 550 Ti 98496 MB/sec
GeForce GTX 870M 96000 MB/sec
Difference: 2496 (3%)

Texel Rate

The GeForce GTX 870M should be quite a bit (more or less 266%) better at anisotropic filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 870M 105392 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 76592 (266%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 870M is a better choice, though not by far. (explain)

GeForce GTX 870M 22584 Mpixels/sec
GeForce GTX 550 Ti 21600 Mpixels/sec
Difference: 984 (5%)

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 max amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 are applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
