GeForce 930M vs GeForce GT 130

Intro

Compare all that to the GeForce GT 130, which has GPU clock speed of 500 MHz, and 768 MB of DDR2 memory running at 250 MHz through a 192-bit bus. It also features 48 Stream Processors, 24 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 930M is 20% faster than the GeForce GT 130 in general, due to its greater bandwidth. (explain)

GeForce 930M		14400 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 2400 (20%)

Texel Rate

The GeForce 930M will be much (approximately 86%) better at texture filtering than the GeForce GT 130. (explain)

GeForce 930M		22272 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 10272 (86%)

Pixel Rate

The GeForce GT 130 will be a small bit (more or less 8%) more effective at AA than the GeForce 930M, and also able to handle higher resolutions better. (explain)

GeForce GT 130		8000 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 576 (8%)

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 data (counted in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 in one second. This figure is worked out by multiplying the total number of texture units 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
