GeForce GTX 465 vs GeForce GTX 660

Intro

The GeForce GTX 465 comes with a clock speed of 607 MHz and a GDDR5 memory frequency of 802 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 352 SPUs, 44 TAUs, and 32 Raster Operation Units.

Compare that to the GeForce GTX 660, which comes with GPU core speed of 980 MHz, and 2048 MB of GDDR5 memory set to run at 1502 MHz through a 192-bit bus. It also is made up of 960 SPUs, 80 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 660 140 Watts
GeForce GTX 465 200 Watts
Difference: 60 Watts (43%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 660 should be 41% quicker than the GeForce GTX 465 in general, because of its higher bandwidth. (explain)

GeForce GTX 660 144192 MB/sec
GeForce GTX 465 102592 MB/sec
Difference: 41600 (41%)

Texel Rate

The GeForce GTX 660 will be a lot (about 194%) faster with regards to anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTX 660 78400 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 51692 (194%)

Pixel Rate

The GeForce GTX 660 should be much (approximately 21%) better at AA than the GeForce GTX 465, and also should be able to handle higher screen resolutions better. (explain)

GeForce GTX 660 23520 Mpixels/sec
GeForce GTX 465 19424 Mpixels/sec
Difference: 4096 (21%)

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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 are processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better 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 most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
