GeForce 930M vs GeForce GT 130

Intro

The GeForce 930M features a GPU core clock speed of 928 MHz, and the 2048 MB of DDR3 memory is set to run at 900 MHz through a 64-bit bus. It also is made up of 384 Stream Processors, 24 TAUs, and 8 ROPs.

Compare those specifications to the GeForce GT 130, which has GPU clock speed of 500 MHz, and 768 MB of DDR2 RAM set to run at 250 MHz through a 192-bit bus. It also is made up of 48 Stream Processors, 24 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 930M should in theory be a small bit superior to 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 much (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 will be a small bit (approximately 8%) better at FSAA than the GeForce 930M, and also should be able to handle higher resolutions without slowing down too much. (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.

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has 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 number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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