Nvidia Titan X vs Radeon RX 470

Intro

Compare those specifications to the Radeon RX 470, which makes use of a 14 nm design. AMD has set the core frequency at 926 MHz. The GDDR5 memory is set to run at a speed of 1650 MHz on this specific model. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470		120 Watts
Nvidia Titan X		250 Watts
	Difference: 130 Watts (108%)

Memory Bandwidth

As far as performance goes, the Nvidia Titan X should theoretically be a lot superior to the Radeon RX 470 overall. (explain)

Nvidia Titan X		491520 MB/sec
Radeon RX 470		211200 MB/sec
	Difference: 280320 (133%)

Texel Rate

The Nvidia Titan X is quite a bit (more or less 168%) more effective at AF than the Radeon RX 470. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon RX 470		118528 Mtexels/sec
	Difference: 198880 (168%)

Pixel Rate

If running with a high screen resolution is important to you, then the Nvidia Titan X is superior to the Radeon RX 470, and very much so. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon RX 470		29632 Mpixels/sec
	Difference: 106400 (359%)

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 MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at 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 its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
