GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 560

Intro

Compare all of that to the GeForce GTX 560, which comes with a GPU core clock speed of 810 MHz, and 1024 MB of GDDR5 memory set to run at 1001 MHz through a 256-bit bus. It also is comprised of 336 Stream Processors, 56 Texture Address Units, and 32 ROPs.

Theoretically speaking, the GeForce GTX 560 should be 401% quicker than the GeForce 9500 GT 1GB GDDR3 overall, due to its higher 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 is much (approximately 415%) more effective at 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 using a high resolution 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 maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
