Nvidia Titan X vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which comes with a GPU core clock speed of 926 MHz, and 8192 MB of GDDR5 RAM set to run at 1650 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 32 Raster Operation 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

Theoretically speaking, the Nvidia Titan X should be much faster than 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 will be a lot (approximately 168%) faster with regards to anisotropic filtering than the Radeon RX 470. (explain)

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

Pixel Rate

The Nvidia Titan X should be quite a bit (approximately 359%) more effective at anti-aliasing than the Radeon RX 470, and should be capable of handling higher resolutions without losing too much performance. (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: Bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If 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 per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
