GeForce 930M vs GeForce GT 130

Intro

Compare those specs to the GeForce GT 130, which comes with core speeds of 500 MHz on the GPU, and 250 MHz on the 768 MB of DDR2 memory. It features 48 SPUs along with 24 TAUs and 16 ROPs.

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 higher bandwidth. (explain)

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

Texel Rate

The GeForce 930M should be a lot (more or less 86%) more effective at AF 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 should be a bit (approximately 8%) more effective at FSAA than the GeForce 930M, and will be capable of handling higher 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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 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 texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video 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 that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends 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.
