Dota 2 before and after Ryzen patch:

That looks quite a nice boost- 30fps, although lets not forget Dota 2 is pretty easy to run so it's probably more important to look at the % difference. This does at least show that at least in some circumstances there are things that can be done to better utilize ryzen on the developers end (I'd be curious to know what they did precisely). My guess is this type of optimisation is likely to benefit Ryzen in situations where it's performance doesn't make sense- e.g. games like AOTS that are shown to scale well on higher core count Intel parts but don't show scaling on Ryzen, or the few cases where Ryzen shows a drop in fps with SMT on but Intel either stays the same or gains performance thanks to SMT.
Recent info about the new X399 platform coming from CanardPC. Clocks in second gen engineering sample are 3.1GHz base and 3.6GHz turbo. But those engineering samples are using B1-grade silicon; therefore don't expect improvements from better silicon. The marketing TDP is 180W. The real TDP is expected to be higher than 200W.
Does this mean we think the 16c / 32t Ryzen 'extreme' platform is real?! I must admit I thought this was just wishful thinking but I'd be happy to be proven wrong! As for the TDP, to push those speeds on that many cores looks pretty good even at around 220W (it is double an R7 after all)- I'm guessing there will be a lower speed version with a much lower TDP (down to 130 - 140W range at say 2.5ghz) that's more in line with the server parts for those who don't want to deal with the higher heat dissipation.
I am using Ryzen 1700 since about three weeks. I notice windows 10 running is not always smooth or good performance. I assume Ryzen CPU is too new... Maybe Windows 10 is not ready for AMD's new Ryzen and wait for microsoft provide patch for Ryzen? Ryzen's new SMT is issue with windows 10.
That's strange, Windows 10 runs smoothly on almost all hardware. Can you be a bit more specific about A: what is your overall specification- if you are running on an old HDD for example that would hold back performance? B: What power profile are you using- there is a known issue with Ryzen that currently Windows 10 tends to park cores when it shouldn't resulting in a delay waking them back up- switching from 'balanced' to 'high performance' stops this behaviour (and there is an update due to Windows to sort that out)... Final thing, what exactly is 'not always smooth or good performance'? I would have thought the OS itself would always be smooth on such a powerful cpu, heck my old fx 8320 runs Windows 10 very nicely, is it a specific application that is causing you issues?
As for the SMT issue, that has been shown to be working as intended (essentially Windows just treats it the same as it does Intel's Hyper-threading, the only possible issue is Windows might move threads between the two CCX core blocks when ideally it wouldn't but that is a fairly limited issue that mainly affects games).
Final thought: I saw this video (there's also another by Linus which tends to agree with this)- a 'simulated' Ryzen 5 benchmark (achieved by disabling cores on an R7):

This is exactly what I was hoping for- for gaming the cut down hex core and quad core parts both exhibit almost the exact same performance profile as the more expensive R7 at a lower price. No they aren't faster (only a higher clocked single CCX Ryzen part would theoretically be quicker for gaming), however given the R7 isn't actually a *bad* performer (the benchmarks on average place it neck and neck with the i7 4790k and just ahead of the i5 7600k which are both regarded as powerful gaming cpu's after all) the issue is just the R7 is a bit expensive if looking purely at gaming. The R5 parts bring this cost down to a level that makes sense for the performance on offer imo.
