GeForce GT 340 vs GeForce GTX 560

Intro

Compare that to the GeForce GTX 560, which makes use of a 40 nm design. nVidia has set the core frequency at 810 MHz. The GDDR5 memory works at a speed of 1001 MHz on this particular card. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.

GeForce GT 340		69 Watts
GeForce GTX 560		150 Watts
	Difference: 81 Watts (117%)

Memory Bandwidth

Performance-wise, the GeForce GTX 560 should in theory be quite a bit better than the GeForce GT 340 in general. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 73728 (136%)

Texel Rate

The GeForce GTX 560 will be quite a bit (about 158%) more effective at AF than the GeForce GT 340. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 27760 (158%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 560 is the winner, by a large margin. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GT 340		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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total number 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
