GeForce GTX 275 vs GeForce GTX 570

Intro

Compare all that to the GeForce GTX 570, which comes with a GPU core clock speed of 732 MHz, and 1280 MB of GDDR5 memory set to run at 950 MHz through a 320-bit bus. It also is made up of 480 Stream Processors, 60 TAUs, and 40 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GTX 570 should theoretically perform a little bit faster than the GeForce GTX 275 in general. (explain)

GeForce GTX 570		152000 MB/sec
GeForce GTX 275		127008 MB/sec
	Difference: 24992 (20%)

Texel Rate

The GeForce GTX 275 should be just a bit (approximately 15%) more effective at texture filtering than the GeForce GTX 570. (explain)

GeForce GTX 275		50640 Mtexels/sec
GeForce GTX 570		43920 Mtexels/sec
	Difference: 6720 (15%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 570 is a better choice, by a large margin. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 11556 (65%)

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 transported past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
