GeForce 920M vs GeForce GT 130

Intro

The GeForce 920M comes with a core clock frequency of 954 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 64-bit bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 32 TAUs, and 8 Raster Operation Units.

Compare all that to the GeForce GT 130, which has a core clock speed of 500 MHz and a DDR2 memory speed of 250 MHz. It also uses a 192-bit bus, and uses a 55 nm design. It is comprised of 48 SPUs, 24 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 920M, in theory, should be just a bit faster than the GeForce GT 130 in general. (explain)

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

Texel Rate

The GeForce 920M is quite a bit (about 154%) better at texture filtering than the GeForce GT 130. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the GeForce GT 130 is a better choice, though not by far. (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 maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 processed per second. This figure is calculated by multiplying the total amount of texture units of the card 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
