GeForce GTX 460 2GB vs GeForce GTX 550 Ti

Intro

The GeForce GTX 460 2GB comes with a GPU core clock speed of 675 MHz, and the 2048 MB of GDDR5 RAM runs at 900 MHz through a 256-bit bus. It also is made up of 336 Stream Processors, 56 Texture Address Units, and 32 ROPs.

Compare those specifications to the GeForce GTX 550 Ti, which has a GPU core clock speed of 900 MHz, and 1024 MB of GDDR5 memory running at 1026 MHz through a 192-bit bus. It also is comprised of 192 SPUs, 32 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 550 Ti 116 Watts
GeForce GTX 460 2GB 160 Watts
Difference: 44 Watts (38%)

Memory Bandwidth

The GeForce GTX 460 2GB, in theory, should perform a small bit faster than the GeForce GTX 550 Ti overall. (explain)

GeForce GTX 460 2GB 115200 MB/sec
GeForce GTX 550 Ti 98496 MB/sec
Difference: 16704 (17%)

Texel Rate

The GeForce GTX 460 2GB will be quite a bit (more or less 31%) better at anisotropic filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 460 2GB 37800 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 9000 (31%)

Pixel Rate

Both cards have exactly the same pixel rate, so in theory they should be equally good at at anti-aliasing, and be capable of handling 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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
