GeForce GTX 460 (OEM) vs GeForce GTX 465

Intro

Compare all that to the GeForce GTX 465, which has a core clock frequency of 607 MHz and a GDDR5 memory speed of 802 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It features 352 SPUs, 44 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 (OEM) is 6% faster than the GeForce GTX 465 in general, because of its greater bandwidth. (explain)

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

Texel Rate

The GeForce GTX 460 (OEM) should be a lot (about 36%) more effective at texture filtering than the GeForce GTX 465. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 9692 (36%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 (OEM) is the winner, but it probably won't make a huge difference. (explain)

GeForce GTX 460 (OEM)		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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
