These benchmarks show better performance than most of the others I've read this week. There's a few surprises in this review given that other sites showed performance in the 3060 to 3060 Ti range consistently. Seeing the 6700 XT beat the 3070 in a few tests is unexpected. I suppose that means AMD has been hard at work tweaking their drivers for better performance. The power consumption doesn't look as bad as I had been led to believe either. Looks like a solid GPU.

I think the 6700 XT could be a good replacement for my 1070. However, do I really want to waste even more time fighting bots, adding to cart only to be unable to checkout, or being led to believe I have a shot at getting a GPU when I really never did? No. I'm not waking up early to watch a page that instantly flips from "coming soon" to "sold out" again.
 
Mining Performance -
In the case of the RX 6700 XT, we settled on 50% maximum GPU clocks (which doesn't actually mean 50%, but whatever — actually clocks settled in around 2.13GHz)
Sooo, you don't actually know how to detune the CPU, or? Hint - toggle that "advanced control" slider to ON.

Power efficiency is poor as expected. Meh. That tiny chainsaw whacked off a few too many CUs.

And if you knew how AMD's drivers and tuning section work, you'd understand that toggling that "advanced control" slider just changes the percentage into a MHz number. Hint - toggle the "condescending tone" slider to OFF.

But I did make an error: I was looking at the memory clock, not the GPU clock, when I thought the GPU was still running at 2.13GHz. I've done a bit more investigating, now that I'm more awake (it was a late night, again — typical GPU launch). With the slider at 40% (which gives a MHz number of something like 1048MHz), I got nearly the same mining performance as with the slider at 65% (1702MHz). Here are three screenshots, showing 40%, 50%, and 65% Max Frequency settings (but with advanced control ticked on so you can see the MHz values). This is with the Sapphire Nitro+, so the clocks are slightly higher than the reference card, but the performance is pretty similar (actually, the reference card was perhaps slightly faster at mining for some reason — only like 0.3MH/s, but still.)

I've updated the text to remove the note about the max frequency not appearing to work properly. It does, my bad, the description of the tuned settings was and is still correct: 50% Max Freq, 112% power, 2150MHz GDDR6, slightly steeper fan curve, 115-120W.

We're interested in hearing your thoughts on what features matter most as well. We know AMD and Nvidia make plenty of noise about certain technologies, but we question how many people actually use the tech. If you have strong feelings for or against a particular tech, let us know in the comments section.
To answer your question, I would say that the most interesting AMD feature is Chill. Sure, it's useless if you're only looking for max FPS or benchmark scores. But on a practical standpoint, for the average gamer, it works wonder. This is particularly true when used with a Freesync monitor and setting the Chill min and max values to the range supported by the monitor, thus always keeping the FPS in the Freesync range. There's no obvious difference when playing most games (particularly for the average gamer not involved in competitive esports), but the card then runs significantly cooler and thus quieter, making for a overall more pleasant gaming experience.

Asus released their 6700 XT cards about an hour ago...for $350 over AMD's MSRP. The 6700 XT is an absolutely horrific value at $829. The stupid things still sold out almost instantly. Plenty of humans on Twitter complaining about bots buying everything up and immediately flipping the cards on Ebay. AMD and Asus have a lot of explaining to do.

My 1070 is now worth double what I paid for it. I'm going to sell it this weekend and forget about AAA gaming for the rest of the year. Plenty of indie games get by happily with lower-end GPUs or iGPs.

No explaining to do here, it is simply the free market at work. Demand is higher than supply? Raise prices until equilibrium is reached.
AMD's release date isn't until 9 AM EDT tomorrow morning -- not today. There were also no promised anti-bot measures in place, again, as usual. AMD's AIB's are also far more aggressive about marking up Radeon prices as compared to RTX prices.
Not sure what the OP was hoping for - a golden ticket system like Willy Wonka?!
Yeah, that would be swell.

What I seriously want to do is just checkout with 1 GPU without the GPU being ripped out of my cart mid-checkout or the vendor cancelling the order after it's been placed.

I forgot what time they went on sale and checked within 5 minutes of the release and they are sold out online everywhere. You can get a couple different ones from a physical Microcenter location as they are in store only. Two of those are at MSRP even.

I still want a cheaper GPU but I am attempting to get a 6700 XT and will use it and flip it if they release even cheaper GPU's. I should have tried for the 3060 but was not yet ready to bite the bullet.

Well it is asus. What to expect!
Asus 3060... more than $600... asus 3070... you don´t need to know ;)
This is not good year to buy gpu... Maybe 2023 is better...
