In-depth Ryzen 7 technical analysis in non-gaming scenarios

https://forums.anandtech.com/threads/ryzen-strictly-technical.2500572/

IMPORTANT INFO.

SMT was not deactivated in many reviews leading to regressions in gaming performance:

The regressions are reasonably noticeable and many review sites are not aware of this.

Update!!

The SMT issue is down to Windows 10. It looks like The Stilt has done even more testing:

https://forums.anandtech.com/threads/ryzen-strictly-technical.2500572/page-8#post-38775732


I did some 3D testing and eventhou there is not nearly enough data to confirm it, I'd say the SMT regression is infact a Windows 10 related issue.
In 3D testing I did recently on Windows 10, the title which illustrated the biggest SMT regression was Total War: Warhammer.

All of these were recorded at 3.5GHz, 2133MHz MEMCLK with R9 Nano:

Windows 10 - 1080 Ultra DX11:

8C/16T - 49.39fps (Min), 72.36fps (Avg)
8C/8T - 57.16fps (Min), 72.46fps (Avg)

Windows 7 - 1080 Ultra DX11:

8C/16T - 62.33fps (Min), 78.18fps (Avg)
8C/8T - 62.00fps (Min), 73.22fps (Avg)

At the moment this is just pure speculation as there were variables, which could not be isolated.
Windows 10 figures were recorded using PresentMon (OCAT), however with Windows 7 it was necessary to use Fraps.

http://www.pcgameshardware.de/Ryzen-7-1800X-CPU-265804/Tests/Test-Review-1222033/

It seems the 4C versions which appear to use only one CCX might be fine.

It looks like Hardware.fr has done some more testing with SMT off.

But here is the big kicker!!

They tested in performance mode and found not all the regressions were actually only down to SMT! ;)

Edit!!

PS: Mods, Hardware.fr provide forum links for their review graphs,as they seem fine for direct linking of their images.

08/03/2017 Update

Another day another potential issue which might have hampered performance at launch:

Just ban Gigabyte boards for using old AGESA and make mainboard tab mandatory for AM4 submissions. Not sure about MSI or ASRock but it's not possible to do this on ASUS.

I seriously think with any AMD launch you need +3 months added to the launch to actually get an accurate picture!! :p

A few notes - SMT has performance regressions in games which AMD obviously did not tell reviewers.

It seems the CPUs won't have windows drivers for a month and AMD knew this.

Apparently,you also need to test the CPUs with the windows performance power plan enabled too.
 
That's fascinating... if this translates into a general gaming boost in a couple of months when drivers and BIOSes can be updated, then the value of money on these is looking really high!

...still going to be interested in whether the 4-6 core parts have better OCing headroom due to thermals ^^;

Its why I think AMD just made things look worse by rushing out the launch. I am kind of a sad panda because of this - so many will just read the first benchmarks.
 
OP updated.

So after reading through a couple of reviews so far it seems these R7 chips don't really offer someone like me who pretty much only games on his PC much interest.

I was looking for a significant upgrade to an overclocked i5 3570k. Before the release of Zen the only upgrade path was an i7 7700k, but its £350 price soon put an end to that.

Seeing as these new Zen chips start at £320 + and only seem to be matching or performing worse than a 7600k/7700k at stock for roughly the same price, then I see no point for me. I don't really care about cinebench or handbrake scores at all.

I will wait and see what AMD's R5 series is like. Their 4c/8t is rumoured to be about £200 and their 6c/12t around £250, if these offer an upgrade (albeit not as much as a 7700k) then at least these will be significantly cheaper than the i7 7700k.

All I'm personally after is a CPU that's a significant upgrade to my overclocked i5 3570k for around £200-£250

AMD has launched these in a subpar condition - SMT has regressions in performance and no windows drivers too.
 
Even if your right and unfortunately AMD are notorious for this the slower memory speeds alone will always be a limit.

But it's not a million miles away from intel and they are massively cheaper and that's what AMD are good at.

This is shocking:

The regressions are massive and many review sites are not aware of this.

Also here is what AMD is saying regarding the patch:

Legitreviews guy said:
You hit the nail on the head on all your comments. I really wish the Windows drivers were ready before we were given the parts to review. Instead we got a statement 24 hours before launch from AMD saying that they'll be coming in 30 days if all goes well. Game optimizations will be hit or miss when they come, but they appear to be coming. That takes time though and we'll see what happens.

I put it in the conclusion on the last page. The quote came direct from AMD's John Taylor. There was talk of it coming with Ryzen 5 and then they said 'in the next month' in an official statement that was e-mailed out last night.
 
Wow didn't realise the SMT on and off has such a difference!

Yep,and this is why I know people are getting annoyed at me for mentioning it all the time,but many reviews have it on when testing gaming - it makes things look a bit better for AMD if its switched off in a number of games.

Hexus saw the same:

Total War: Warhammer is the one title that causes us some pause for thought. It's known to be driven by solid CPU performance, so seeing the Ryzen 7 1800X a fair bit behind a quartet of Intel chips, to the tune of 10fps, is not encouraging. Understanding that the AMD and Intel architectures are more similar than ever before, we're not sure how much of this gap can be bridged by forthcoming game optimisations.

However, and somewhat interesting to note, switching off the chip's SMT capability increased the average frame rate from 79fps to 85.8fps, suggesting that code is not running efficiently when there's SMT involved. Hopefully this problem will be fixed by a game-patch update.

Going back to SMT, switching it off also increases the Hitman score, from 91.4fps to 95.6fps, suggesting, once again, that having it active is definitely hindering performance. In fact, running Ryzen in non-SMT mode offers more performance in every scenario, and this is something that AMD needs to be concerned about.

It appears SMT is not properly supported under Windows for gaming yet,so is not helping.
 
I was having a discussion about why SMT might cause issues on another forum,and it is mentioned in the Hardware.fr review:

http://www.hardware.fr/articles/956-22/retour-sous-systeme-memoire.html

What someone had to say about it:

According to that, one of the biggest issues for Ryzen in gaming (and some other workoads) is actual extremely high latency and low bandwidth between the CCXes, which is exacerbated in moderately threaded situations by Windows 10 regularly moving threads between cores. If a thread gets moved and its data is now in the other CCX's L3, it'll end up with a cache miss and a huge latency penalty getting that data back in.

Assuming 4C Ryzen works by completely deactivating one CCX (which seems logical given the halving of L3 cache as well) that won't be a problem for it - there won't be another CCX for threads to get migrated to. So part of the problem may be mitigated inherently by the method of harvesting dies...!

EDIT: looking at the SMT scaling you posted, it looks like Civ and GTA V are least affected, which I believe are the most CPU intensive games in that list? That would make sense if Windows 10 only moves threads in situations where cores are lightly loaded - put lots of load on the cores and no thread movement so no cache misses; lightly load the cores, more thread movement, more cache misses. That'd be easily fixable in driver or scheduler - simply tell the scheduler not to move active threads...!

So it seems the 4C/8T models might actually less affected and it seems AMD launching this before proper Windows patches has caused the problem.



So a 6900k has SMT/HT problems as well?

Only one game it regresses by 1.9% but in EVERY game tested it regressed on the R7 1800X and sometimes upto 13% and Hexus saw the same.

Hexus saw the same. You are doing people a disservice by trying to hide it - in many games the R7 1800X will perform better with SMT disabled until the windows patches are released.

Many reviews tested with SMT on and this is why some of them seem to get very poor results.
 
Tl; dr Nothing to worry about, good CPU, soon sorted with a few software patches ;)
Its why I am frustrated with AMD - they knew this was the case,and I had to gleam it from the comments section of a review they were waiting on windows patches still.

If only they have got a lot of reviews to also test with SMT off,it would look a bit better for AMD. Places like Ars Technica didn't do that so,but even 10% on top of their results would have made the summary a tad different methinks.

I just hope when the R5 1600X is out we have some scheduler patches released.
