Looks interesting!
Quite annoying not knowing just how these things will change performance - I've got the funds waiting

I am running large settlements,and with mods,and one thread of my Xeon E3 1230 V2 is pegged at 70% to 80% usage. The others have far less usage.
To put in context a Core i3 7350K is faster than my IB Core i7 in the game.
Its behaviour which was seen even on Intel CPUs at launch:
http://www.gamegpu.com/images/stories/Test_GPU/RPG/Fallout_4/test/intel.jpg
Look at the Core i7 5960X - it has the same problem.
Now look at some forum testing done with a 4GHZ R7 1700.
Default Win = 47,5fps.
HT ON + one CCX active = 49fps.
HT OFF + one CCX active = 50fps.
So running only 4 cores with 4 cores deactivated and no SMT improved performance.
Other CPUs tested on the forum using the same save:
6700k 4.5Ghz 3Ghz ddr4 80Fps
xeon 4030Mhz 2120DDR3 59Fps
2600k 4500mhz DDR3 1600mhz 54fps.
Broadwell server CPU at 2.5GHZ~3.3GHZ 58FPS
Area tested:Boston Commons
Apparently the engine loves memory bandwidth,and is why an overclocked SKL/KL CPU does so well in the game,so if Ryzen can start supporting higher speed RAM better,that is where the biggest improvement will be.
However,Bethesda are really taking the **** with even using it for FO4 - Creation is based on this engine:
https://en.wikipedia.org/wiki/Gamebryo
The original version of the engine came out in 1991 and Bethesda have been using it since 2002 in The Elder Scrolls III: Morrowind.

Like most other things, I think it will vary a lot based on the application. Some will see no change, others will see a significant difference.Quite annoying not knowing just how these things will change performance - I've got the funds waiting

AdoredTV got owned , 2500k still spanking the FX 8370K in 2017.

How? adoredtv only quoted results from computerbase... so you and this guy are trying to say Computerbase tests got owned? Would still trust them more
Soldato
lol what, it's adored TV making the claims and he just got debunked on youtube, servers him right for plundering others benchmarks without doing his own research.
Soldato
AdoredTV is a fraud and clearly an AMD fanboy. He can't see things objectively. He didn't even bother test his amazing investigative finding.

How is he a fraud?
So despite PCpers article on the scheduler where they state the following:
They now have this video where they conclude; the scheduler needs to be aware of the two CCXs..because at the moment it's not....
So what needs to be done? Well the Windows 10 Scheduler still need to be "fixed" so it can actually work correctly with Ryzen.
Conclusion at 26:23

The thing is though, despite this issue, the only part where Ryzen falls behind Intel is in gaming, and many people and some sites are finding that if you disable one CCX, aka turning it into a 4c/8t CPU; that at clock for clock it's closed the gape with Kabylake in gaming.
As we all know, Ryzen is extremely powerful and has great IPC; it's seen in every workload. Everything but gaming; and it means once this issue is addressed Ryzen will be competitive in all scenarios.
Ignoring that the 6 and 4 core R5 line is still to come as well.
Another thing that still needs to be addressed is the motherboard issue. It's been seen that the "Infinity Fabric" runs at 1/2 RAM speeds. So the faster your RAM, the faster the interconnect between CCXs. Which in turn boosts performance even further.
So motherboard manufacturers still need to get that sort. So if you're buying a Ryzen system at the moment, do make sure to get up to atleast 3200Mhz RAM. It'll work eventually, and it'll be well worth it.
On a side note: this whole RAM speed issue and buggy motherboards brings back memories of the x99 launch. Took mobo makers a while to get that all sorted, and all the other bugs.
Only to then do a little bit more testing, and find oh that the scheduler is not handling Ryzen correctly, because it's still spilling workloads into the second CCX when it's not supposed to.

Yeah sorry he has taken a very well known and trusted site and used their figures to show something and provide information. For you to suggest he is in the wrong when all he has done is research all the info and provide a conclusion from the figures provided is no problem.
His research was using a credible source the same as we do when we read everything on here or there or the clip you linked. They are only what we can see or show.

It makes you wonder why they didn't just launch it later!!
Maybe it's similar to games releases where because of how complicated todays games are are they need masses of feedback to get everything working right.
there is a tendency to do that as you can basically work on things to long without really knowing if its ready for launch.
star citizen may be different tho
New launch its why I wait for all to settle down with hardware and software with bios, mikrocode before buying Ryzen
Pretty substantial FPS gains in games when running Ryzen with a single CCX compared to two in some games. That Windows Scheduler update can not come fast enough.
In their tests they completed disabled one CCX, and also went half half ( still two CCXs ), and SMT disabled.

Good test.
Explains why Duke Nukem Forever was the greatest game in history
In fairness you could say the exact same about the Radeon HD7000 series. When it launched the flagship HD7970 could barely keep up with the GTX670, but after all the patches, firmware updates, etc it was closer to the GTX780 than the GTX680 (which was now being dueled by the HD7950)It makes you wonder why they didn't just launch it later!!
