GeForce GT 340 vs GeForce GTX 860M

Intro

Compare those specs to the GeForce GTX 860M, which has core speeds of 797 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 RAM. It features 1152 SPUs along with 96 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 860M		45 Watts
GeForce GT 340		69 Watts
	Difference: 24 Watts (53%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 860M should theoretically be a small bit superior to the GeForce GT 340 in general. (explain)

GeForce GTX 860M		64000 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 9600 (18%)

Texel Rate

The GeForce GTX 860M should be quite a bit (approximately 335%) better at anisotropic filtering than the GeForce GT 340. (explain)

GeForce GTX 860M		76512 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 58912 (335%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 860M is superior to the GeForce GT 340, and very much so. (explain)

GeForce GTX 860M		12752 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 8352 (190%)

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 max amount of information (measured in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 are processed per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
