Nvidia Titan X vs Radeon RX Vega 56

Intro

Compare those specifications to the Radeon RX Vega 56, which features GPU clock speed of 1156 MHz, and 8192 MB of HBM2 memory running at 1600 MHz through a 2048-bit bus. It also is made up of 3584 Stream Processors, 224 Texture Address Units, and 64 Raster Operation Units.

Radeon RX Vega 56		419430 MB/sec
	Difference: 72090 (17%)

Texel Rate

The Nvidia Titan X is much (approximately 23%) more effective at texture filtering than the Radeon RX Vega 56. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon RX Vega 56		258944 Mtexels/sec
	Difference: 58464 (23%)

Pixel Rate

If running with a high resolution is important to you, then the Nvidia Titan X is the winner, by far. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon RX Vega 56		73984 Mpixels/sec
	Difference: 62048 (84%)

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 (counted in MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 can be processed in one second. This number is worked out by multiplying the total 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
