GeForce 930M vs GeForce GT 130

Intro

Compare all that to the GeForce GT 130, which features core clock speeds of 500 MHz on the GPU, and 250 MHz on the 768 MB of DDR2 RAM. It features 48 SPUs along with 24 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 930M should perform a bit faster than the GeForce GT 130 in general. (explain)

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

Texel Rate

The GeForce 930M is a lot (approximately 86%) more effective at anisotropic 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 is just a bit (approximately 8%) more effective at anti-aliasing than the GeForce 930M, and will be capable of handling higher screen resolutions more effectively. (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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
