GeForce 9500 GT 512MB GDDR3 vs GeForce GTX 570

Intro

Compare those specs to the GeForce GTX 570, which uses a 40 nm design. nVidia has set the core frequency at 732 MHz. The GDDR5 RAM works at a speed of 950 MHz on this particular model. It features 480 SPUs along with 60 TAUs and 40 Rasterization Operator 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 is 494% faster than the GeForce 9500 GT 512MB GDDR3 in general, because of its greater bandwidth. (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 quite a bit (more or less 399%) faster with regards to AF 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

If running with high levels of AA is important to you, then the GeForce GTX 570 is a better choice, and very much so. (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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
