GeForce 9400 GT 256MB vs GeForce GTX 560 Ti

Intro

Compare those specs to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has clocked the core frequency at 822 MHz. The GDDR5 memory runs at a speed of 1002 MHz on this particular model. It features 384 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

GeForce 9400 GT 256MB		50 Watts
GeForce GTX 560 Ti		170 Watts
	Difference: 120 Watts (240%)

Memory Bandwidth

In theory, the GeForce GTX 560 Ti will be 902% quicker than the GeForce 9400 GT 256MB overall, due to its higher bandwidth. (explain)

GeForce GTX 560 Ti		128256 MB/sec
GeForce 9400 GT 256MB		12800 MB/sec
	Difference: 115456 (902%)

Texel Rate

The GeForce GTX 560 Ti will be much (more or less 1096%) more effective at anisotropic filtering than the GeForce 9400 GT 256MB. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce 9400 GT 256MB		4400 Mtexels/sec
	Difference: 48208 (1096%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 560 Ti is superior to the GeForce 9400 GT 256MB, and very much so. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce 9400 GT 256MB		2200 Mpixels/sec
	Difference: 24104 (1096%)

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 (counted in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 are applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
