GeForce GTX 260 Core 216 vs GeForce GTX 570

Intro

Compare that to the GeForce GTX 570, which comes with GPU core speed of 732 MHz, and 1280 MB of GDDR5 RAM set to run at 950 MHz through a 320-bit bus. It also is comprised of 480 Stream Processors, 60 Texture Address Units, and 40 Raster Operation Units.

GeForce GTX 260 Core 216		202 Watts
GeForce GTX 570		219 Watts
	Difference: 17 Watts (8%)

Memory Bandwidth

The GeForce GTX 570, in theory, should perform quite a bit faster than the GeForce GTX 260 Core 216 in general. (explain)

GeForce GTX 570		152000 MB/sec
GeForce GTX 260 Core 216		111888 MB/sec
	Difference: 40112 (36%)

Texel Rate

The GeForce GTX 570 will be just a bit (more or less 6%) better at anisotropic filtering than the GeForce GTX 260 Core 216. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce GTX 260 Core 216		41472 Mtexels/sec
	Difference: 2448 (6%)

Pixel Rate

The GeForce GTX 570 should be a lot (approximately 82%) better at AA than the GeForce GTX 260 Core 216, and also should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 13152 (82%)

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 maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better 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 most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
