GeForce GTX 460 1GB vs GeForce GTX 550 Ti
Intro
The GeForce GTX 460 1GB has core speeds of 675 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs as well as 56 TAUs and 32 ROPs.Compare those specifications to the GeForce GTX 550 Ti, which uses a 40 nm design. nVidia has set the core speed at 900 MHz. The GDDR5 memory works at a frequency of 1026 MHz on this specific card. It features 192 SPUs as well as 32 TAUs and 24 Rasterization Operator Units.

Texel Rate
The GeForce GTX 460 1GB will be a lot (about 31%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)| GeForce GTX 460 1GB |
|
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 AA, and be able to handle the same 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 data (in units of megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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.
