Nvidia Titan X vs Radeon RX 6800

Intro

Compare those specs to the Radeon RX 6800, which features GPU core speed of 1700 MHz, and 16384 MB of GDDR6 memory running at 2000 MHz through a 256-bit bus. It also features 3840 SPUs, 240 Texture Address Units, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 should perform a bit faster than the Nvidia Titan X overall. (explain)

Radeon RX 6800		524288 MB/sec
Nvidia Titan X		491520 MB/sec
	Difference: 32768 (7%)

Texel Rate

The Radeon RX 6800 should be quite a bit (approximately 29%) more effective at anisotropic filtering than the Nvidia Titan X. (explain)

Radeon RX 6800		408000 Mtexels/sec
Nvidia Titan X		317408 Mtexels/sec
	Difference: 90592 (29%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6800 is superior to the Nvidia Titan X, but only just. (explain)

Radeon RX 6800		163200 Mpixels/sec
Nvidia Titan X		136032 Mpixels/sec
	Difference: 27168 (20%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number 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 filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
