SPCR

In brief: Great 1440p/low 2160p, Performance is between GTX1080 and RTX 2060 Super. Does not support CrossFire, does support PCIe-4.0. 180W TDP, but OEM stock OC'ed cards will use more at high loads. HDMI 2.0b and Display Port 1.4a. Supports dual link DVI-D but not analog. Requires one 6-pin and one 8-pin PCIe Graphics power connector, but OEM designs may use more. Dimensions stated as: a" x b" x c" are from mfgr websites - others are from reviews. High multi-monitor power use due to memory clock.

PowerColor 5700 RED DEVIL; good cooler + not so high power --> very quiet:

Looking at TPU's review database, there's a few more reviews to add:

Hexus: Sapphire Pulse
Looks good, but perhaps a rung below some other models for SPCR purposes.

Guru3d: Asus ROG STRIX
Looking VERY solid - same measured noise level as the PowerColor Red Devil, but running ~10 degrees cooler, so you could probably put a custom fan curve on to lower the noise further without making the card run hot.

Computer Base: PowerColor Red Devil (German)
This shows the Red Devil running extremely quietly on its silent BIOS.

eTeknix: PowerColor Red Dragon
Not showing much difference between cards on either temperature or noise - wonder why that's happening? In any case, the Red Dragon appears to have middling thermals and middling acoustics in this review, but I don't know how good this data is.

Computer Base: Asus TUF and PowerColor Red Dragon (Germans)
Paints the Red Dragon is a pretty good light, not too far behind the Red Devil in noise or temperatures with the one exception of noise while using the Silent BIOS where it's behind 3 dB; the TUF on the other hand looks to be quite frankly awful, running 2 degrees cooler than the Red Dragon but 10 (!!) dB louder (nearly as bad as the stock cooler).

TechPowerUp: PowerColor Red Dragon
Pretty good showing for the Red Dragon with moderate temperatures but very low noise - however, problems with fans ramping up over-aggressively from idle.

OverclockersClub has another PowerColor Red Devil review, but there doesn't seem to be dedicated acoustics or temperature testing? The conclusion just mentions that the card has "great cooling" with "quiet fans". ¯\_(ツ)_/¯

Mad Shrimps also has one for the Red Dragon, but the noise results probably aren't especially applicable since they tested noise at specific fan speed percentages. Interesting information to have on hand, but doesn't help much when figuring out if the card is quiet or not.

Had some time - review links are up.
