GeForce 920M vs GeForce GT 430 1GB

Intro

Compare those specifications to the GeForce GT 430 1GB, which features a GPU core clock speed of 700 MHz, and 1024 MB of GDDR3 RAM set to run at 900 MHz through a 128-bit bus. It also is made up of 96 SPUs, 16 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 430 1GB should theoretically perform a lot faster than the GeForce 920M overall. (explain)

GeForce GT 430 1GB		28800 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 14400 (100%)

Texel Rate

The GeForce 920M should be much (more or less 173%) more effective at anisotropic filtering than the GeForce GT 430 1GB. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 19328 (173%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 920M is superior to the GeForce GT 430 1GB, by far. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce GT 430 1GB		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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 are processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
