GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 560

Intro

Compare those specs to the GeForce GTX 560, which makes use of a 40 nm design. nVidia has set the core frequency at 810 MHz. The GDDR5 RAM is set to run at a frequency of 1001 MHz on this specific card. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

In theory, the GeForce GTX 560 should be 401% quicker than the GeForce 9500 GT 1GB GDDR3 overall, due to its greater bandwidth. (explain)

GeForce GTX 560		128128 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 102528 (401%)

Texel Rate

The GeForce GTX 560 will be much (more or less 415%) faster with regards to anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 36560 (415%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 560 is a better choice, by far. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 21520 (489%)

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 largest amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
