GeForce GTX 550 Ti vs GeForce GTX 560 Ti

Intro

The GeForce GTX 550 Ti makes use of a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 memory works at a frequency of 1026 MHz on this particular card. It features 192 SPUs along with 32 TAUs and 24 ROPs.

Compare all that to the GeForce GTX 560 Ti, which comes with clock speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

(No game benchmarks for this combination yet.)

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 550 Ti 116 Watts
GeForce GTX 560 Ti 170 Watts
Difference: 54 Watts (47%)

Memory Bandwidth

Theoretically, the GeForce GTX 560 Ti should perform quite a bit faster than the GeForce GTX 550 Ti overall. (explain)

GeForce GTX 560 Ti 128256 MB/sec
GeForce GTX 550 Ti 98496 MB/sec
Difference: 29760 (30%)

Texel Rate

The GeForce GTX 560 Ti is quite a bit (about 83%) better at texture filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 560 Ti 52608 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 23808 (83%)

Pixel Rate

The GeForce GTX 560 Ti will be much (more or less 22%) more effective at anti-aliasing than the GeForce GTX 550 Ti, and also able to handle higher resolutions better. (explain)

GeForce GTX 560 Ti 26304 Mpixels/sec
GeForce GTX 550 Ti 21600 Mpixels/sec
Difference: 4704 (22%)

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 (counted in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, 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 number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
