GeForce GTX Titan X vs Radeon RX 6800

Intro

Compare all that to the Radeon RX 6800, which has a clock frequency of 1700 MHz and a GDDR6 memory speed of 2000 MHz. It also uses a 256-bit bus, and uses a 7 nm design. It is comprised of 3840 SPUs, 240 Texture Address Units, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 6800 will be 56% faster than the GeForce GTX Titan X in general, due to its greater data rate. (explain)

Radeon RX 6800		524288 MB/sec
GeForce GTX Titan X		336000 MB/sec
	Difference: 188288 (56%)

Texel Rate

The Radeon RX 6800 should be a lot (approximately 113%) faster with regards to anisotropic filtering than the GeForce GTX Titan X. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce GTX Titan X		192000 Mtexels/sec
	Difference: 216000 (113%)

Pixel Rate

The Radeon RX 6800 will be quite a bit (more or less 70%) faster with regards to full screen anti-aliasing than the GeForce GTX Titan X, and should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce GTX Titan X		96000 Mpixels/sec
	Difference: 67200 (70%)

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 data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
