GeForce 9500 GT 512MB GDDR3 vs GeForce GTX 570

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 512MB GDDR3		50 Watts
GeForce GTX 570		219 Watts
	Difference: 169 Watts (338%)

Memory Bandwidth

In theory, the GeForce GTX 570 should be 494% quicker than the GeForce 9500 GT 512MB GDDR3 in general, due to its higher data rate. (explain)

GeForce GTX 570		152000 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 126400 (494%)

Texel Rate

The GeForce GTX 570 is a lot (approximately 399%) better at texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 35120 (399%)

Pixel Rate

The GeForce GTX 570 will be much (more or less 565%) more effective at full screen anti-aliasing than the GeForce 9500 GT 512MB GDDR3, and also should be able to handle higher resolutions more effectively. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		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 data (measured in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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