GeForce GT 340 vs GeForce GTX 560 Ti

Intro

Compare all that to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has set the core speed at 822 MHz. The GDDR5 memory is set to run at a frequency of 1002 MHz on this specific card. It features 384 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

GeForce GT 340		54400 MB/sec
	Difference: 73856 (136%)

Texel Rate

The GeForce GTX 560 Ti should be a lot (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 is quite a bit (approximately 498%) faster with regards to AA than the GeForce GT 340, and also will be able to handle higher resolutions without slowing down too much. (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 largest amount of data (measured in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can 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 Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
