GeForce 930M vs Geforce GTX 690

Intro

Compare all of that to the Geforce GTX 690, which has a clock frequency of 915 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 256-bit bus, and uses a 28 nm design. It is made up of 1536 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Geforce GTX 690 is 2570% quicker than the GeForce 930M overall, due to its higher bandwidth. (explain)

Geforce GTX 690		384512 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 370112 (2570%)

Texel Rate

The Geforce GTX 690 will be a lot (approximately 952%) more effective at texture filtering than the GeForce 930M. (explain)

Geforce GTX 690		234240 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 211968 (952%)

Pixel Rate

If using high levels of AA is important to you, then the Geforce GTX 690 is a better choice, and very much so. (explain)

Geforce GTX 690		58560 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 51136 (689%)

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 data (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, 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 most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
