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

Theoretically speaking, the GeForce GTX 860M should be 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 will be quite a bit (more or less 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

If using a high resolution is important to you, then the GeForce GTX 860M is a better choice, by a large margin. (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 largest amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 are applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
