GeForce 930M vs GeForce GT 130

Intro

The GeForce 930M comes with a clock frequency of 928 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit memory bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Compare all that to the GeForce GT 130, which features a core clock frequency of 500 MHz and a DDR2 memory frequency of 250 MHz. It also makes use of a 192-bit bus, and uses a 55 nm design. It is comprised of 48 SPUs, 24 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 930M should be just a bit faster 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 (about 86%) faster with regards to 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 will be just a bit (more or less 8%) more effective at full screen anti-aliasing than the GeForce 930M, and also should be 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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
