GeForce GTX 460 SE vs GeForce GTX 660 Ti

Intro

Compare all of that to the GeForce GTX 660 Ti, which uses a 28 nm design. nVidia has set the core speed at 915 MHz. The GDDR5 memory works at a frequency of 1500 MHz on this card. It features 1344 SPUs along with 112 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the GeForce GTX 660 Ti should theoretically be quite a bit superior to the GeForce GTX 460 SE in general. (explain)

GeForce GTX 660 Ti		144000 MB/sec
GeForce GTX 460 SE		108800 MB/sec
	Difference: 35200 (32%)

Texel Rate

The GeForce GTX 660 Ti is quite a bit (approximately 228%) better at AF than the GeForce GTX 460 SE. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 71280 (228%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 660 Ti is superior to the GeForce GTX 460 SE, though only just barely. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
GeForce GTX 460 SE		20800 Mpixels/sec
	Difference: 1160 (6%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 can be applied 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 this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
