GeForce GTX 460 (OEM) vs Nvidia Titan X

Intro

Compare all of that to the Nvidia Titan X, which has a clock speed of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also makes use of a 384-bit memory bus, and uses a 16 nm design. It is made up of 3584 SPUs, 224 Texture Address Units, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460 (OEM)		150 Watts
Nvidia Titan X		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X should be 352% quicker than the GeForce GTX 460 (OEM) overall, because of its higher bandwidth. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GTX 460 (OEM)		108800 MB/sec
	Difference: 382720 (352%)

Texel Rate

The Nvidia Titan X is quite a bit (about 772%) faster with regards to AF than the GeForce GTX 460 (OEM). (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 281008 (772%)

Pixel Rate

If running with a high resolution is important to you, then the Nvidia Titan X is the winner, and very much so. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GTX 460 (OEM)		20800 Mpixels/sec
	Difference: 115232 (554%)

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 megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 maximum fill rate.
