GeForce GT 340 1GB vs GeForce GTX 560

Intro

Compare all of that to the GeForce GTX 560, which makes use of a 40 nm design. nVidia has set the core speed at 810 MHz. The GDDR5 RAM works at a frequency of 1001 MHz on this specific card. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340 1GB		69 Watts
GeForce GTX 560		150 Watts
	Difference: 81 Watts (117%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 560 should in theory be much superior to the GeForce GT 340 1GB overall. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 73728 (136%)

Texel Rate

The GeForce GTX 560 should be quite a bit (more or less 158%) faster with regards to anisotropic filtering than the GeForce GT 340 1GB. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 27760 (158%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 560 is a better choice, and very much so. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GT 340 1GB		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 information (measured in MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
