GeForce 930M vs GeForce 9800 GT 512MB

Intro

The GeForce 930M makes use of a 28 nm design. nVidia has set the core frequency at 928 MHz. The DDR3 RAM is set to run at a frequency of 900 MHz on this particular model. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Compare that to the GeForce 9800 GT 512MB, which makes use of a 65/55 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this specific card. It features 112 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

GeForce 930M 22272 Mtexels/sec
Difference: 11328 (51%)

Pixel Rate

The GeForce 9800 GT 512MB will be a lot (about 29%) more effective at FSAA than the GeForce 930M, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce 9800 GT 512MB 9600 Mpixels/sec
GeForce 930M 7424 Mpixels/sec
Difference: 2176 (29%)

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 data (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
