GeForce 920M vs Geforce GTX 690

Intro

Compare all of that to the Geforce GTX 690, which features GPU core speed of 915 MHz, and 2048 MB of GDDR5 memory set to run at 1502 MHz through a 256-bit bus. It also features 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.

GeForce 920M		30528 Mtexels/sec
	Difference: 203712 (667%)

Pixel Rate

If running with a high screen resolution is important to you, then the Geforce GTX 690 is superior to the GeForce 920M, by a large margin. (explain)

Geforce GTX 690		58560 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 50928 (667%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
