GeForce GTX 580 vs Nvidia Titan X

Intro

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

GeForce GTX 580		49408 Mtexels/sec
	Difference: 268000 (542%)

Pixel Rate

The Nvidia Titan X will be much (about 267%) better at AA than the GeForce GTX 580, and will be capable of handling higher resolutions while still performing well. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GTX 580		37056 Mpixels/sec
	Difference: 98976 (267%)

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 (in units of megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
