I'm deeply skeptical about the hype, here.
So far we're having to make assumptions about certain pipelines, but just based on the physical specifications alone, it's laughable to present the RX 6900 XT as a competitor to the RTX 3090. The 300W TDP doesn't seem realistic for this card, either. I suspect the actual power consumption will exceed that by more than GPUs usually exceed their quoted TDP; particularly relative to the RTX 3000 series. The enormous difference between the core clock and boost clocks on the AMD cards tingles my spidey senses, and the whopping 2GHz memory clock doesn't assuage my concerns. It reeks of a card being pushed to the limit with its narrow bus and inferior memory standard just to keep its VRAM from being dusted, and it's still getting clobbered. The 7nm advantage certainly doesn't justify any of these discrepancies. To be blunt, I'm concerned about a repeat of the heat issues that plagued the Vega release.
The RX 6800 XT is obviously the best buy of the bunch, and yet, superficially, before we see actual benchmarks, on paper, I can't imagine how it will perform well enough to warrant a recommendation at $649 over the RTX 3080 for $699, especially when we consider its deep-learning deficiency.
