I think it has something to do with the changes for memory write processes. AFAIK write bandwidth was cut in half on the 3000 series in order to boost performance in areas that are more beneficial to the mainstream platform consumer; Steve on HWUB mentions the bit width for write processes was cut from 32-bit to 16-bit

I would have liked to have seen a Ryzen 7 3800X review (maybe they are still coming later today), especially to see the gaming results. With its 105w TDP, those higher sustained clocks could probably get it much closer to the 9900K, while still costing $100 less. Overall though, this is pretty much what I was expecting. AMD is back to the top of the CPU game in about every sense.

Gaming still needs work by third parties, because either Windows 10's thread scheduler still isn't working properly, despite the claims that it is now topology aware, or some games need to be updated, because in some games there's a lot of fuel in the tank:

They should mature in the coming weeks with all the new bios updates that didn't make it into these reviews. They look good so far. But i want to see 3800x and 3400G reviews.

So much for believing in AMD’s slides where the 3900x had “identical” gaming performance as 9900k lol

Computer Base actually has it within 3% of the 9900K. I think they used AGESA 1003. Their gaming performance is very strong with Ryzen beating the 9900K in some games.

That is factually wrong. First of all, they said that it was "comparable" and secondly, in the 3900X vs 9990K gaming slide they showed it winning in 3 games out of 8, tying in one and losing in four:

Looking back now I guess many of us(Including me) were being pretty silly not to assume they were probably using a radeon VII or navi card, numbers must have been GPU bottlenecked. Scratch that, not so sure anymore.

You know what yeah, I can only find one benchmark with one of those games tested on the 3900X - GTA V, and it is tied. Interesting. So who knows.
Edit: Found a 2nd, pretty much tied still at stock, very marginally worse.

Not a fan of Linus but I think he summarized it well.
If you do anything other than game, it makes no sense to go with Intel. That means if you game and stream as well , video edit your videos if you record while playing, or do anything in the background.


A bigger unforeseen issue that hasn't been addressed is the day 1 Linux support. I'll be waiting for this to be rectified before purchase.

On the likes of Ubuntu 18.04 LTS, these new AMD Ryzen 7/9 series 7nm processors deliver incredible performance with the newest AMD X570 motherboards. The support on the likes of Ubuntu 18.04 LTS is great except for possible compatibility issues depending upon the particular motherboard/ASICs employed.


...
While Ubuntu 18.04 LTS and older Linux distributions boot Zen 2, to date I have not been able to successfully boot the likes of Ubuntu 19.04, Manjaro Linux, and Fedora Workstation 31. On all newer Linux distributions I've tried on two different systems built around the Ryzen 7 3700X and Ryzen 9 3900X, each time early in the boot process as soon as trying to start systemd services, all systemd services fail to start.


...
Complicating this issue further is that when trying Linux 5.0/5.1/5.2 kernels on Ubuntu 18.04 LTS, they all booted up fine! Hence it doesn't appear to simply be a kernel regression but either some kernel+systemd interaction issue happening just on AMD Ryzen 3000 series processors or some awkward thing happening with the X570 chipset.
So all the top distros don't work on certain systems.


level1techs testing:
Fedora 30 doesn't boot on bare metal

So, Lexi, what are you gonna replace your R5 1600 with? I have one, too, and i think it suffers from segfault. Thinking either the 3600 or the 3700X. BUT, we have not seen the 3800X perform.
