GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 560

Intro

Compare that to the GeForce GTX 560, which has a clock speed of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 Texture Address Units, and 32 ROPs.

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

Texel Rate

The GeForce GTX 560 is a lot (about 415%) faster with regards to AF 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 lots of anti-aliasing is important to you, then the GeForce GTX 560 is superior to the GeForce 9500 GT 1GB GDDR3, and very much so. (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: Bandwidth is the max amount of data (in units of MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount 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 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 chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
