GeForce GTX 460 SE vs GeForce GTX 465

Intro

Compare those specs to the GeForce GTX 465, which features a GPU core clock speed of 607 MHz, and 1024 MB of GDDR5 RAM running at 802 MHz through a 256-bit bus. It also is made up of 352 SPUs, 44 Texture Address Units, and 32 Raster Operation Units.

GeForce GTX 460 SE		150 Watts
GeForce GTX 465		200 Watts
	Difference: 50 Watts (33%)

Memory Bandwidth

Theoretically, the GeForce GTX 460 SE should perform a bit faster than the GeForce GTX 465 in general. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 6208 (6%)

Texel Rate

The GeForce GTX 460 SE is just a bit (approximately 17%) faster with regards to AF than the GeForce GTX 465. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 4492 (17%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is superior to the GeForce GTX 465, though only just barely. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 1376 (7%)

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 max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
