GeForce 920M vs GeForce GT 130

Intro

The GeForce 920M uses a 28 nm design. nVidia has clocked the core frequency at 954 MHz. The DDR3 memory runs at a speed of 900 MHz on this particular model. It features 384 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Compare those specs to the GeForce GT 130, which has a core clock speed of 500 MHz and a DDR2 memory speed of 250 MHz. It also features a 192-bit bus, and makes use of a 55 nm design. It features 48 SPUs, 24 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 920M should be a little bit faster than the GeForce GT 130 overall. (explain)

GeForce 920M 14400 MB/sec
GeForce GT 130 12000 MB/sec
Difference: 2400 (20%)

Texel Rate

The GeForce 920M is a lot (approximately 154%) better at AF than the GeForce GT 130. (explain)

GeForce 920M 30528 Mtexels/sec
GeForce GT 130 12000 Mtexels/sec
Difference: 18528 (154%)

Pixel Rate

The GeForce GT 130 will be a bit (more or less 5%) faster with regards to full screen anti-aliasing than the GeForce 920M, and will be able to handle higher resolutions better. (explain)

GeForce GT 130 8000 Mpixels/sec
GeForce 920M 7632 Mpixels/sec
Difference: 368 (5%)

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 data (in units of megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
