recent W10 patch, March15, shows some improvements for Ryzen

Recommended Posts

Posted · Original PosterOP

source:

although not particularly stated by MicroSoft, one of the March 15th updates to Windows 10 has some Ryzen tweaks

as the source shows, no gains in TW: Warhammer, Cinebench, HandBrake nor Batman: AA; but a 35% increase in UT3 benchmark tool of ~35% (not 45% as stated in the tweet)

from what I'm getting, the new scheduler behaviour is to prioritize work to cores (0, 2, 4, 6, 8, 10, 12, 14) and not SMT threads (1, 3, 5, 7, 9, 11, 13, 15) - kinda treating it as SMT off

lol wtf

 

35% from an OS patch?

 

why didn't AMD sort this scheduler stuff out with Microsoft before launch? Day zero reviews count.

to be clear, it's only one test, not even a game test

also, the scheduler appears to treat Ryzen as SMT off, it occupies all cores (main threads) ignoring the hyperthreads 

 

the patch could've also altered the power plan as some people have reported the FMA issue is gone

That's not really the point. Anyone who has been around tech long enough knows that CPU releases aren't instantly optimized, whether early samples are released or not. Results like this are expected; maybe not 35%, but it'd be almost impossible to see zero improvement in the next few months after updates, patches, and new games come out.

Unreal Tournament 3 seems like a really pointless game to benchmark. Something like even the Source engine would be better for benchmarking. Oh well, we'll wait and see how else this improves shit.

It'd be a better basis than UT3. I've never seen anyone talk about UT3, but you have people playing TF2 and CSGO all day everyday.

I would prefer new testing be done sometime in June or July for the whole platform.  By then, hopefully there will have been enough in the way of updates to actually get a feel for the Zen platform and what it's strength, weaknesses and growth potential are.  Part of the reason I try to avoid being a Day One adopter on any new technology release, be it GPU, CPU or even game console and phones.  Always have bugs that need to be worked out.

Not exactly the most prominent benchmarks to use, but at least it prioritises the actual cores themselves now, instead of saturating a cores resources while others are left idling.

?? Apart from 64 tick servers being horrible, fps wise, I have nothing against CSGO...

I mean I get 450fps~ on D2, 400fps~ on mirage/cache/overpass and 300-350fps on Newke, Infenew and Train so...it's not that bad...(lowest 1080p by the way)

Still, a performance improvement is still an improvement :P

As a wise man once said, if you think I'm wrong and have facts to back it up with (not opinions) then I'll happily accept that you're correct. Remember, the facts has to be valid and comes from a "noteworthy" source.

As another wise man once said, if you don't have anything to say then please don't say anything unless you like a big fat sausage in your buns...

As a third wise man once said, tickle other's like how you want to be...oh wait, treat I mean, not tickle...whoops :P

Give it a month or two. We could still be seeing tweaks OS-side in the near future.

CSGO scales pretty well across multiple cores, but takes a hit with HT on.

It seems like the scheduler is using the cores correctly now, that's nice :)

Let's hope someone takes the time to rebench ryzen properly.

Maybe it does use SMT but it just sticks to 1 cpu module so the CCX doesn't need to be utilized to allow communication between cores.

 

I mean it went from utilizing 10 treads to 8 and the utilized cores are now at 100% constantly which wasn't the case before. Could be because the cores were waiting for information from other cores that had to go through the CCX thingy...

 

It's too early to conclude what exactly is going on, but they clearly fixed something. But i don't know what exactly...

I vote to ban posts from sources that are always from some random outlet in Asia that shows some very sketchy claims. But just like how the forum lords won't change the title of "Tech News and Reviews" to just "Tech News", this probably won't happen even if the rules in this section says:

here's my i3 hyperthreaded for comparison:

see the difference? it doesn't prioritize cores over SMT

 

compared to setting affinity to thread 0 and 2:

if MS is doing this, they should treat both equally

I was not expecting Ryzen performance to improve that much... Dang. Perhaps there is hope for Ryzen gaming benchmarks to catch up to the 6900k...

I seem to like any products who have the same software and hardware maker, as long as it's not Apple. Weird. I like the Surface Book and the Pixel phones, but most definitely don't want an iPhone or another Mac (I'm not saying they're bad, though).

 

Interested in computer architecture? Still in middle or high school? P.M. me!

 

I love computer hardware and feel free to ask me anything about that (or phones) but please do not ask me anything about Networking, programming, command line stuff, or any relatively hard software stuff. I know next to nothing about that.
