GeForce GTX 580 3GB vs GeForce GTX Titan X

Intro

Compare all of that to the GeForce GTX Titan X, which uses a 28 nm design. nVidia has clocked the core frequency at 1000 MHz. The GDDR5 RAM is set to run at a frequency of 1750 MHz on this model. It features 3072 SPUs along with 192 Texture Address Units and 96 Rasterization Operator Units.

	Difference: 143616 (75%)

Texel Rate

The GeForce GTX Titan X will be quite a bit (about 289%) faster with regards to AF than the GeForce GTX 580 3GB. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 142592 (289%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX Titan X is the winner, by a large margin. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce GTX 580 3GB		37056 Mpixels/sec
	Difference: 58944 (159%)

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 largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
