GeForce GTX 465 vs GeForce GTX 560

Intro

Compare all of that to the GeForce GTX 560, which comes with clock speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 465		102592 MB/sec
	Difference: 25536 (25%)

Texel Rate

The GeForce GTX 560 should be quite a bit (more or less 70%) better at anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 18652 (70%)

Pixel Rate

The GeForce GTX 560 will be quite a bit (about 33%) more effective at anti-aliasing than the GeForce GTX 465, and also should be capable of handling higher screen resolutions better. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 6496 (33%)

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 information (measured in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
