Nvidia Titan X vs Radeon RX 6800 XT

Intro

Compare all that to the Radeon RX 6800 XT, which features a core clock frequency of 1825 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 256-bit bus, and makes use of a 7 nm design. It is comprised of 4608 SPUs, 288 TAUs, and 128 Raster Operation Units.

Nvidia Titan X		317408 Mtexels/sec
	Difference: 208192 (66%)

Pixel Rate

The Radeon RX 6800 XT should be a lot (about 72%) faster with regards to anti-aliasing than the Nvidia Titan X, and able to handle higher resolutions while still performing well. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Nvidia Titan X		136032 Mpixels/sec
	Difference: 97568 (72%)

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 max amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
