GeForce 930M vs GeForce 9800 GX2

Intro

The GeForce 930M uses a 28 nm design. nVidia has set the core frequency at 928 MHz. The DDR3 memory works at a speed of 900 MHz on this specific model. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Compare those specifications to the GeForce 9800 GX2, which features clock speeds of 600 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR3 RAM. It features 128 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce 9800 GX2 should in theory be a lot superior to the GeForce 930M in general. (explain)

GeForce 9800 GX2 128000 MB/sec
GeForce 930M 14400 MB/sec
Difference: 113600 (789%)

Texel Rate

The GeForce 9800 GX2 should be much (approximately 245%) more effective at texture filtering than the GeForce 930M. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
GeForce 930M 22272 Mtexels/sec
Difference: 54528 (245%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 9800 GX2 is the winner, by far. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
GeForce 930M 7424 Mpixels/sec
Difference: 11776 (159%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a 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 - 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
