GeForce GTX 460 2GB vs GeForce GTX 550 Ti
Intro
The GeForce GTX 460 2GB comes with a clock speed of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It is comprised of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.Compare all that to the GeForce GTX 550 Ti, which uses a 40 nm design. nVidia has set the core speed at 900 MHz. The GDDR5 RAM runs at a speed of 1026 MHz on this specific card. It features 192 SPUs as well as 32 Texture Address Units and 24 ROPs.

37800 Mtexels/sec |
| GeForce GTX 550 Ti |
|
28800 Mtexels/sec |

Pixel Rate
Both cards have exactly the same pixel rate, so in theory they should perform equally good at at full screen anti-aliasing, and be capable of handling the same screen resolutions. (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.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at 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 that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
