GeForce GTX 580 vs Nvidia Titan X

Intro

Compare all of that to the Nvidia Titan X, which features clock speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X memory. It features 3584 SPUs along with 224 TAUs and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 580		244 Watts
Nvidia Titan X		250 Watts
	Difference: 6 Watts (2%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X should be quite a bit faster than the GeForce GTX 580 in general. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GTX 580		192384 MB/sec
	Difference: 299136 (155%)

Texel Rate

The Nvidia Titan X should be much (approximately 542%) more effective at AF than the GeForce GTX 580. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 268000 (542%)

Pixel Rate

The Nvidia Titan X should be quite a bit (about 267%) better at anti-aliasing than the GeForce GTX 580, and will be capable of handling higher screen resolutions without slowing down too much. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
