GeForce 9500 GT 512MB GDDR3 vs GeForce GTX 570

Intro

Compare those specs to the GeForce GTX 570, which makes use of a 40 nm design. nVidia has clocked the core speed at 732 MHz. The GDDR5 memory is set to run at a speed of 950 MHz on this specific model. It features 480 SPUs as well as 60 Texture Address Units and 40 ROPs.

The GeForce GTX 570 will be a lot (more or less 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 is a lot (approximately 565%) more effective at AA than the GeForce 9500 GT 512MB GDDR3, and also will be capable of handling 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 max amount of information (measured in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
