GeForce 8800 Ultra vs GeForce 930M

Intro

Compare all that to the GeForce 930M, which uses a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The DDR3 RAM works at a frequency of 900 MHz on this specific card. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 8800 Ultra should be quite a bit faster than the GeForce 930M overall. (explain)

GeForce 8800 Ultra		103680 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 89280 (620%)

Texel Rate

The GeForce 8800 Ultra should be quite a bit (more or less 76%) faster with regards to texture filtering than the GeForce 930M. (explain)

GeForce 8800 Ultra		39168 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 16896 (76%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 8800 Ultra is superior to the GeForce 930M, by a large margin. (explain)

GeForce 8800 Ultra		14688 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 7264 (98%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
