GeForce GT 320 vs GeForce GTX 570

Intro

Compare those specifications to the GeForce GTX 570, which makes use of a 40 nm design. nVidia has set the core frequency at 732 MHz. The GDDR5 memory is set to run at a frequency of 950 MHz on this particular model. It features 480 SPUs as well as 60 TAUs and 40 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
GeForce GTX 570		219 Watts
	Difference: 176 Watts (409%)

Memory Bandwidth

The GeForce GTX 570 should in theory perform quite a bit faster than the GeForce GT 320 overall. (explain)

GeForce GTX 570		152000 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 126720 (501%)

Texel Rate

The GeForce GTX 570 will be much (more or less 239%) more effective at AF than the GeForce GT 320. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 30960 (239%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 570 is superior to the GeForce GT 320, and very much so. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 24960 (578%)

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 largest amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface 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 bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
