Geforce GTX 680 vs Nvidia Titan X

Intro

Compare all that to the Nvidia Titan X, which makes use of a 16 nm design. nVidia has set the core speed at 1417 MHz. The GDDR5X memory is set to run at a speed of 1251 MHz on this model. It features 3584 SPUs as well as 224 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 680		195 Watts
Nvidia Titan X		250 Watts
	Difference: 55 Watts (28%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X should be 156% faster than the Geforce GTX 680 in general, because of its higher bandwidth. (explain)

Nvidia Titan X		491520 MB/sec
Geforce GTX 680		192256 MB/sec
	Difference: 299264 (156%)

Texel Rate

The Nvidia Titan X will be quite a bit (about 146%) more effective at anisotropic filtering than the Geforce GTX 680. (explain)

Nvidia Titan X		317408 Mtexels/sec
Geforce GTX 680		128768 Mtexels/sec
	Difference: 188640 (146%)

Pixel Rate

The Nvidia Titan X is much (approximately 323%) more effective at FSAA than the Geforce GTX 680, and also will be capable of handling higher screen resolutions while still performing well. (explain)

Nvidia Titan X		136032 Mpixels/sec
Geforce GTX 680		32192 Mpixels/sec
	Difference: 103840 (323%)

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: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
