GeForce 930M vs GeForce GT 130

Intro

Compare those specs to the GeForce GT 130, which comes with a GPU core clock speed of 500 MHz, and 768 MB of DDR2 memory set to run at 250 MHz through a 192-bit bus. It also features 48 Stream Processors, 24 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 930M should theoretically be a bit better than the GeForce GT 130 overall. (explain)

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

Texel Rate

The GeForce 930M will be quite a bit (more or less 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 little bit (about 8%) better at full screen anti-aliasing than the GeForce 930M, and also capable of handling 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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
