Nvidia Titan X vs Radeon Vega Frontier Edition

Intro

Compare those specifications to the Radeon Vega Frontier Edition, which makes use of a 14 nm design. AMD has clocked the core frequency at 1382 MHz. The HBM2 RAM runs at a frequency of 1890 MHz on this particular card. It features 4096 SPUs as well as 256 Texture Address Units and 64 Rasterization Operator Units.

Nvidia Titan X		491520 MB/sec
	Difference: 3932 (1%)

Texel Rate

The Radeon Vega Frontier Edition is a bit (approximately 11%) faster with regards to anisotropic filtering than the Nvidia Titan X. (explain)

Radeon Vega Frontier Edition		353792 Mtexels/sec
Nvidia Titan X		317408 Mtexels/sec
	Difference: 36384 (11%)

Pixel Rate

The Nvidia Titan X should be much (more or less 54%) more effective at AA than the Radeon Vega Frontier Edition, and also will be able to handle higher screen resolutions better. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon Vega Frontier Edition		88448 Mpixels/sec
	Difference: 47584 (54%)

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 largest amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
