GeForce 930M vs GeForce GT 130

Intro

The GeForce 930M has 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 SPUs, 24 Texture Address Units, and 8 ROPs.

Compare those specs to the GeForce GT 130, which features clock speeds of 500 MHz on the GPU, and 250 MHz on the 768 MB of DDR2 memory. It features 48 SPUs along with 24 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 930M should be 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 will be quite a bit (approximately 86%) faster with regards to 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 is a bit (more or less 8%) faster with regards to full screen anti-aliasing than the GeForce 930M, and also capable of handling higher screen 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.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at handling 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 video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
