GeForce GTX 460 SE vs GeForce GTX 550 Ti

Intro

The GeForce GTX 460 SE uses a 40 nm design. nVidia has set the core frequency at 650 MHz. The GDDR5 memory runs at a speed of 850 MHz on this card. It features 288 SPUs along with 48 TAUs and 32 ROPs.

Compare all that to the GeForce GTX 550 Ti, which makes use of 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 along with 32 TAUs and 24 ROPs.

GeForce GTX 550 Ti 98496 MB/sec
Difference: 10304 (10%)

Texel Rate

The GeForce GTX 460 SE is a little bit (approximately 8%) faster with regards to anisotropic filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 460 SE 31200 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 2400 (8%)

Pixel Rate

The GeForce GTX 550 Ti should be just a bit (more or less 4%) more effective at anti-aliasing than the GeForce GTX 460 SE, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 550 Ti 21600 Mpixels/sec
GeForce GTX 460 SE 20800 Mpixels/sec
Difference: 800 (4%)

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 max amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 can be processed in one second. This is calculated by multiplying the total number of 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 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 graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
