GeForce GTX 460 SE vs GeForce GTX 660 Ti

Intro

Compare that to the GeForce GTX 660 Ti, which has a core clock speed of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 192-bit memory bus, and makes use of a 28 nm design. It is comprised of 1344 SPUs, 112 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GTX 660 Ti, in theory, should be a lot faster than the GeForce GTX 460 SE overall. (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 should be much (more or less 228%) faster with regards to 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

The GeForce GTX 660 Ti will be just a bit (approximately 6%) more effective at FSAA than the GeForce GTX 460 SE, and will be able to handle higher screen resolutions more effectively. (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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at 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 chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
