Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340		69 Watts
GeForce GTX 560 Ti		170 Watts
	Difference: 101 Watts (146%)

Memory Bandwidth

In theory, the GeForce GTX 560 Ti should be 136% quicker than the GeForce GT 340 in general, due to its higher data rate. (explain)

GeForce GTX 560 Ti		128256 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 73856 (136%)

Texel Rate

The GeForce GTX 560 Ti should be much (more or less 199%) faster with regards to anisotropic filtering than the GeForce GT 340. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 35008 (199%)

Pixel Rate

The GeForce GTX 560 Ti should be quite a bit (more or less 498%) faster with regards to full screen anti-aliasing than the GeForce GT 340, and also should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 21904 (498%)

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 maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
