Geforce GTX 680 vs Nvidia Titan X

Intro

Compare all that to the Nvidia Titan X, which comes with a core clock frequency of 1417 MHz and a GDDR5X memory frequency of 1251 MHz. It also makes use of a 384-bit bus, and uses a 16 nm design. It is comprised of 3584 SPUs, 224 TAUs, and 96 ROPs.

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

Performance-wise, the Nvidia Titan X should theoretically be quite a bit better than the Geforce GTX 680 in general. (explain)

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

Texel Rate

The Nvidia Titan X will be a lot (approximately 146%) more effective at texture filtering than the Geforce GTX 680. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the Nvidia Titan X is a better choice, by far. (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 largest amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 can be applied per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling 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 could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
