Nvidia Titan X vs Radeon RX Vega 64

Intro

Compare that to the Radeon RX Vega 64, which comes with clock speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 RAM. It features 4096 SPUs as well as 256 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Nvidia Titan X		250 Watts
Radeon RX Vega 64		295 Watts
	Difference: 45 Watts (18%)

Memory Bandwidth

Theoretically speaking, the Radeon RX Vega 64 should be a little bit faster than the Nvidia Titan X overall. (explain)

Radeon RX Vega 64		495411 MB/sec
Nvidia Titan X		491520 MB/sec
	Difference: 3891 (1%)

Texel Rate

The Radeon RX Vega 64 will be just a bit (about 1%) better at texture filtering than the Nvidia Titan X. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
Nvidia Titan X		317408 Mtexels/sec
	Difference: 1824 (1%)

Pixel Rate

If using high levels of AA is important to you, then the Nvidia Titan X is superior to the Radeon RX Vega 64, by a large margin. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon RX Vega 64		79808 Mpixels/sec
	Difference: 56224 (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: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
