GeForce GTX 465 vs GeForce GTX 660 Ti

Intro

The GeForce GTX 465 has a GPU core clock speed of 607 MHz, and the 1024 MB of GDDR5 RAM runs at 802 MHz through a 256-bit bus. It also features 352 SPUs, 44 Texture Address Units, and 32 ROPs.

Compare all of that to the GeForce GTX 660 Ti, which has GPU core speed of 915 MHz, and 2048 MB of GDDR5 RAM set to run at 1500 MHz through a 192-bit bus. It also features 1344 SPUs, 112 TAUs, and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The GeForce GTX 660 Ti should in theory be quite a bit faster than the GeForce GTX 465 overall. (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 quite a bit (approximately 284%) better at texture filtering 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 running with lots of anti-aliasing is important to you, then the GeForce GTX 660 Ti is superior to the GeForce GTX 465, not by a very large margin though. (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.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
