GeForce GTX 465 vs GeForce GTX 570

Intro

Compare all of that to the GeForce GTX 570, which comes with a clock speed of 732 MHz and a GDDR5 memory speed of 950 MHz. It also makes use of a 320-bit memory bus, and uses a 40 nm design. It features 480 SPUs, 60 Texture Address Units, and 40 Raster Operation Units.

GeForce GTX 465		102592 MB/sec
	Difference: 49408 (48%)

Texel Rate

The GeForce GTX 570 will be quite a bit (about 64%) better at anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 17212 (64%)

Pixel Rate

The GeForce GTX 570 is a lot (approximately 51%) better at FSAA than the GeForce GTX 465, and will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 9856 (51%)

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 MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the 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 maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
