GeForce 9500 GT DDR2 vs GeForce GTX 570

Intro

Compare all of that to the GeForce GTX 570, which comes with a clock frequency 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 is made up of 480 SPUs, 60 Texture Address Units, and 40 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT DDR2		50 Watts
GeForce GTX 570		219 Watts
	Difference: 169 Watts (338%)

Memory Bandwidth

In theory, the GeForce GTX 570 should perform quite a bit faster than the GeForce 9500 GT DDR2 overall. (explain)

GeForce GTX 570		152000 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 136000 (850%)

Texel Rate

The GeForce GTX 570 should be quite a bit (about 399%) better at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 35120 (399%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 570 is the winner, by far. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 24880 (565%)

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 (counted in MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 applied per second. This is worked out 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
