GeForce GTX 465 vs GeForce GTX 660 Ti

Intro

Compare those specifications to the GeForce GTX 660 Ti, which has core clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1344 SPUs along with 112 Texture Address Units and 24 ROPs.

GeForce GTX 660 Ti		150 Watts
GeForce GTX 465		200 Watts
	Difference: 50 Watts (33%)

Memory Bandwidth

In theory, the GeForce GTX 660 Ti should perform quite a bit faster than the GeForce GTX 465 in general. (explain)

GeForce GTX 660 Ti		144000 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 41408 (40%)

Texel Rate

The GeForce GTX 660 Ti is a lot (more or less 284%) better at AF than the GeForce GTX 465. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 75772 (284%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 660 Ti is superior to the GeForce GTX 465, but not by far. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 2536 (13%)

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 data (measured in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few 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.
