Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 860M		45 Watts
GeForce GT 430		60 Watts
	Difference: 15 Watts (33%)

Memory Bandwidth

In theory, the GeForce GTX 860M is 122% faster than the GeForce GT 430 overall, due to its greater bandwidth. (explain)

GeForce GTX 860M		64000 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 35200 (122%)

Texel Rate

The GeForce GTX 860M should be much (approximately 583%) faster with regards to anisotropic filtering than the GeForce GT 430. (explain)

GeForce GTX 860M		76512 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 65312 (583%)

Pixel Rate

The GeForce GTX 860M should be quite a bit (about 355%) more effective at AA than the GeForce GT 430, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 860M		12752 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 9952 (355%)

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 (in units of MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
