GeForce GTX 460 SE vs GeForce GTX 465

Intro

Compare all of that to the GeForce GTX 465, which features GPU clock speed of 607 MHz, and 1024 MB of GDDR5 RAM set to run at 802 MHz through a 256-bit bus. It also is comprised of 352 SPUs, 44 Texture Address Units, and 32 ROPs.

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

Pixel Rate

The GeForce GTX 460 SE is a little bit (about 7%) faster with regards to AA than the GeForce GTX 465, and also will be able to handle higher screen resolutions without slowing down too much. (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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
