GeForce 920M vs GeForce GT 430

Intro

Compare those specifications to the GeForce GT 430, which uses a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this particular card. It features 96 SPUs as well as 16 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GT 430 is 100% quicker than the GeForce 920M in general, due to its greater data rate. (explain)

GeForce GT 430		28800 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 14400 (100%)

Texel Rate

The GeForce 920M will be quite a bit (more or less 173%) more effective at anisotropic filtering than the GeForce GT 430. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 19328 (173%)

Pixel Rate

The GeForce 920M should be quite a bit (more or less 173%) more effective at full screen anti-aliasing than the GeForce GT 430, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 4832 (173%)

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 (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
