Nvidia Titan X vs Radeon RX Vega 56

Intro

Compare those specs to the Radeon RX Vega 56, which uses a 14 nm design. AMD has clocked the core frequency at 1156 MHz. The HBM2 RAM works at a speed of 1600 MHz on this model. It features 3584 SPUs as well as 224 Texture Address Units and 64 Rasterization Operator Units.

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

Texel Rate

The Nvidia Titan X will be quite a bit (about 23%) better at AF 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

The Nvidia Titan X is quite a bit (approximately 84%) faster with regards to FSAA than the Radeon RX Vega 56, and also capable of handling higher screen resolutions more effectively. (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 largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 can be applied per second. This figure is calculated by multiplying the total texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
