Geforce GTX 670 vs Nvidia Titan X

Intro

Compare that to the Nvidia Titan X, which features GPU core speed of 1417 MHz, and 12288 MB of GDDR5X RAM set to run at 1251 MHz through a 384-bit bus. It also is comprised of 3584 SPUs, 224 Texture Address Units, and 96 ROPs.

Geforce GTX 670		192000 MB/sec
	Difference: 299520 (156%)

Texel Rate

The Nvidia Titan X is much (approximately 210%) better at texture filtering than the Geforce GTX 670. (explain)

Nvidia Titan X		317408 Mtexels/sec
Geforce GTX 670		102480 Mtexels/sec
	Difference: 214928 (210%)

Pixel Rate

If using a high resolution is important to you, then the Nvidia Titan X is a better choice, by a large margin. (explain)

Nvidia Titan X		136032 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 106752 (365%)

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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
