GeForce GT 340 1GB vs GeForce GTX 660 Ti

Intro

Compare those specifications to the GeForce GTX 660 Ti, which makes use of a 28 nm design. nVidia has set the core speed at 915 MHz. The GDDR5 RAM is set to run at a speed of 1500 MHz on this particular card. It features 1344 SPUs as well as 112 TAUs and 24 ROPs.

GeForce GT 340 1GB		69 Watts
GeForce GTX 660 Ti		150 Watts
	Difference: 81 Watts (117%)

Memory Bandwidth

The GeForce GTX 660 Ti should in theory perform quite a bit faster than the GeForce GT 340 1GB overall. (explain)

GeForce GTX 660 Ti		144000 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 89600 (165%)

Texel Rate

The GeForce GTX 660 Ti will be much (about 482%) better at AF than the GeForce GT 340 1GB. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 84880 (482%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 660 Ti is the winner, by far. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 17560 (399%)

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 (in units of MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units by the core clock 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
