GeForce GTX Titan X vs Radeon RX 460 2GB

Intro

Compare that to the Radeon RX 460 2GB, which uses a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this particular model. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
GeForce GTX Titan X		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

In theory, the GeForce GTX Titan X should be 200% faster than the Radeon RX 460 2GB overall, due to its greater data rate. (explain)

GeForce GTX Titan X		336000 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 224000 (200%)

Texel Rate

The GeForce GTX Titan X is much (more or less 215%) more effective at anisotropic filtering than the Radeon RX 460 2GB. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 130960 (215%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX Titan X is the winner, and very much so. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 78560 (450%)

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 max amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 can be processed per second. This number 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
