GeForce GT 430 1GB		28800 MB/sec
	Difference: 35200 (122%)

Texel Rate

The GeForce GTX 965M is a lot (approximately 439%) more effective at anisotropic filtering than the GeForce GT 430 1GB. (explain)

GeForce GTX 965M		60416 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 49216 (439%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 965M is superior to the GeForce GT 430 1GB, by a large margin. (explain)

GeForce GTX 965M		30208 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 27408 (979%)

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 information (measured in megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher 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 number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
