GeForce 830M vs GeForce GT 130

Intro

The GeForce 830M comes with a clock frequency of 1029 MHz and a DDR3 memory frequency of 900 MHz. It also features a 64-bit bus, and uses a 28 nm design. It features 256 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare those specs to the GeForce GT 130, which makes use of a 55 nm design. nVidia has clocked the core speed at 500 MHz. The DDR2 memory runs at a speed of 250 MHz on this model. It features 48 SPUs as well as 24 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M 25 Watts
GeForce GT 130 75 Watts
Difference: 50 Watts (200%)

Memory Bandwidth

Theoretically, the GeForce 830M should be just a bit faster than the GeForce GT 130 in general. (explain)

GeForce 830M 14400 MB/sec
GeForce GT 130 12000 MB/sec
Difference: 2400 (20%)

Texel Rate

The GeForce 830M should be a lot (about 37%) better at AF than the GeForce GT 130. (explain)

GeForce 830M 16464 Mtexels/sec
GeForce GT 130 12000 Mtexels/sec
Difference: 4464 (37%)

Pixel Rate

The GeForce 830M should be a little bit (more or less 3%) more effective at anti-aliasing than the GeForce GT 130, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 830M 8232 Mpixels/sec
GeForce GT 130 8000 Mpixels/sec
Difference: 232 (3%)

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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once 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 high resolutions.

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