Yep Micron E/B can do some really high clocks. Even past 5000Mhz. The problem is that it cant match B-Die when it comes to low timings. Not even primary ones but also secondary and tertiary. rfc is a good example. B-Die can do between 200-300 easily. Most others do 400-500+
On some points I would disagree, on cl and cwl rev E/B and B-die is quite similar, but on rp, wtrs and wtrl, at 3800 I can do 11 rp, 3 wtrs and 6 wtrl on my rev E, very few B-dies can do that, my average good kit can do 14 rp, 3 wtrs and 9 wtrl, 1T was also way easier to stabilize on rev E, only drvstr at 40-20-30-24 worked on B-die. The only things B-die is superior at is rcdrd at 15 vs 20 on rev E, rc at 40 vs 57 and rfc at 264 vs 528. The majority of the performance comes from rfc, a bit from rc and rcdrd, but rev E makes up a bit of the loss with superior rp. All other timings run equally tight: rrd 4/4, faw 16, ras 21, wr/rtp 10/5.
In SOTTR the B-dies rfc alone gives about 4-5% performance, rc and rcdrd gives about 1% each, but the better rp and wtrl gives about 1% each so in the end the difference between rev E and B-die is 4-5%. On my Ryzen 3600 I could get 164fps with max tweaks, on rev E I got 157fps.
A good binned Micron rev B can do cl14, rcdrd 16, rp 11, rc 50 and rfc 560 so a bit better than rev E.
As for DJR it needs 16 cl, 17+ rcrd and 18+ rp, but can run rc at 48+ and rfc at 400+ so it ends up slightly better than Micron rev E, but on pair with Micron rev B.
