Nvidia Titan X vs Radeon RX 460

Intro

Compare those specifications to the Radeon RX 460, which comes with a clock speed of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 128-bit bus, and makes use of a 14 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460		75 Watts
Nvidia Titan X		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

The Nvidia Titan X should in theory perform much faster than the Radeon RX 460 in general. (explain)

Nvidia Titan X		491520 MB/sec
Radeon RX 460		112000 MB/sec
	Difference: 379520 (339%)

Texel Rate

The Nvidia Titan X should be much (more or less 420%) more effective at AF than the Radeon RX 460. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon RX 460		61040 Mtexels/sec
	Difference: 256368 (420%)

Pixel Rate

The Nvidia Titan X is quite a bit (approximately 680%) better at full screen anti-aliasing than the Radeon RX 460, and also will be able to handle higher resolutions more effectively. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 118592 (680%)

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 information (counted in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
