GeForce 930M		14400 MB/sec
	Difference: 72000 (500%)

Texel Rate

The GeForce GTX 460 should be quite a bit (approximately 70%) faster with regards to texture filtering than the GeForce 930M. (explain)

GeForce GTX 460		37800 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 15528 (70%)

Pixel Rate

The GeForce GTX 460 will be quite a bit (approximately 118%) more effective at FSAA than the GeForce 930M, and will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 460		16200 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 8776 (118%)

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 (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video 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 maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
