Geforce GTX 690 vs Nvidia Titan X

Intro

Compare that to the Nvidia Titan X, which features a GPU core clock speed of 1417 MHz, and 12288 MB of GDDR5X memory running at 1251 MHz through a 384-bit bus. It also is comprised of 3584 SPUs, 224 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Nvidia Titan X		250 Watts
Geforce GTX 690		300 Watts
	Difference: 50 Watts (20%)

Memory Bandwidth

The Nvidia Titan X should theoretically perform a lot faster than the Geforce GTX 690 in general. (explain)

Nvidia Titan X		491520 MB/sec
Geforce GTX 690		384512 MB/sec
	Difference: 107008 (28%)

Texel Rate

The Nvidia Titan X will be quite a bit (about 36%) faster with regards to texture filtering than the Geforce GTX 690. (explain)

Nvidia Titan X		317408 Mtexels/sec
Geforce GTX 690		234240 Mtexels/sec
	Difference: 83168 (36%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Nvidia Titan X is the winner, by a large margin. (explain)

Nvidia Titan X		136032 Mpixels/sec
Geforce GTX 690		58560 Mpixels/sec
	Difference: 77472 (132%)

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 max amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 number is worked out by multiplying the total amount 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
