Nvidia Titan X vs Radeon RX Vega 64

Intro

Compare all that to the Radeon RX Vega 64, which features a clock frequency of 1247 MHz and a HBM2 memory frequency of 1890 MHz. It also makes use of a 2048-bit bus, and uses a 14 nm design. It is comprised of 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

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, the Radeon RX Vega 64 should perform just a 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 a little bit (about 1%) better at anisotropic 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

The Nvidia Titan X is much (approximately 70%) faster with regards to anti-aliasing than the Radeon RX Vega 64, and also should be able to handle higher resolutions without slowing down too much. (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 data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
