Nvidia Titan X vs Radeon VII

Intro

Compare those specifications to the Radeon VII, which has a clock frequency of 1400 MHz and a HBM2 memory frequency of 1000 MHz. It also makes use of a 4096-bit memory bus, and makes use of a 7 nm design. It is comprised of 3840 SPUs, 240 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Nvidia Titan X		250 Watts
Radeon VII		295 Watts
	Difference: 45 Watts (18%)

Memory Bandwidth

In theory, the Radeon VII should perform quite a bit faster than the Nvidia Titan X overall. (explain)

Radeon VII		1048576 MB/sec
Nvidia Titan X		491520 MB/sec
	Difference: 557056 (113%)

Texel Rate

The Radeon VII is a bit (approximately 6%) better at AF than the Nvidia Titan X. (explain)

Radeon VII		336000 Mtexels/sec
Nvidia Titan X		317408 Mtexels/sec
	Difference: 18592 (6%)

Pixel Rate

The Nvidia Titan X will be much (about 52%) better at anti-aliasing than the Radeon VII, and also should be capable of handling higher screen resolutions while still performing well. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon VII		89600 Mpixels/sec
	Difference: 46432 (52%)

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 data (in units of MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
