GeForce GTX 460 1GB vs GeForce GTX 550 Ti

Intro

The GeForce GTX 460 1GB comes with a GPU clock speed of 675 MHz, and the 1024 MB of GDDR5 memory runs at 900 MHz through a 256-bit bus. It also is comprised of 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

Compare that to the GeForce GTX 550 Ti, which has clock speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs as well as 32 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 550 Ti 116 Watts
GeForce GTX 460 1GB 160 Watts
Difference: 44 Watts (38%)

Memory Bandwidth

The GeForce GTX 460 1GB should theoretically perform just a bit faster than the GeForce GTX 550 Ti overall. (explain)

GeForce GTX 460 1GB 115200 MB/sec
GeForce GTX 550 Ti 98496 MB/sec
Difference: 16704 (17%)

Texel Rate

The GeForce GTX 460 1GB will be much (about 31%) better at anisotropic filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 460 1GB 37800 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 9000 (31%)

Pixel Rate

Both cards have the exact same pixel rate, so in theory they should be equally good at at FSAA, and be able to handle 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 data (counted in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 can be processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record 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 speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
