Yes. It should be like $150.
It's priced that way because they really want you to get the 1500X or 1600 instead due to yields being good, I'm sure. If it was $150, they probably couldn't meet the demand.
On that subject, they probably should have made the 1600 and 1600X both $230. Just one...
Lets get back to strictly technical:
Has anyone tried running a common actual workstation application that is open source through another compiler?
As far as I'm aware, ICC will never compile to take advantage of how AMD CPUs have, since forever, handled 4 complex instructions per cycle...
UMS is exactly what I'm talking about.
It's been verified that many games see Ryzen as a 16 core. As in, they are not seeing SMT and are instructing the scheduler accordingly.
Sanders praised that at least in those socialistic dictatorships, people were fed and had health care compared to some other ones.
But everyone knows there's a difference between Social Democracy or Democratic Socialism compared to Authoritarian Socialism - there's just those that like to...
KB4013429 Is the Windows update. It's not going out automatically to everyone, apparently. http://www.catalog.update.microsoft.com/Search.aspx?q=KB4013429
XFR was AMD's biggest mistake.
They should have just marked them as 3.45Ghz and 3.9Ghz "precision boost". Instead they make them look lower clocked and spread this lie that they overclocked them as good as your cooling allowed. :(
"X" just stands for "it's better xD"
Agreed.
But in addition, whatever does account for that latency, I don't think it's purely to blame for some games performing terribly (especially DX12/Vulkan).
I have a feeling there's something besides just the cross-CCX bandwidth that's getting overloaded when something tries to cross them...
Well yes. Without upping the BCLK it doesn't up the interconnect frequency, does it?
Yes. 5 years ago. But I buy hardware for 2017, not 2012.
If you take the average of AAA games released the past 2 years, off the top of my head the gain with HT is about 20% for average FPS and 30-40% for 0.1%...
Anyway, re: how to multithread games
I'm pretty sure the optimal thing, since there clearly seems to be DX12 and Vulkan issues where they rely on the shared cache and interconnectivity, is to have those running on the other CCX and "only" using those 8 threads for the actual graphics API calls...
edit: nvm figured out what I had posted here.
This was with the assumption that the "ping test" is how long it takes for one core to set something into L3 and RAM, and for another core to then read it.
Was thinking that 142ns delay was really because it was fetching from RAM, but no that's...
The bigger problem here is with XFR making them look loer clcoked than they are.
In actuality, the 1500X is 3.5/3.9 and the 1400 is 3.2/3.5
This is because the 1400 gets an extra 100mhz from XFR, and the 1500X uniquely gets an extra 200mhz.
They basically lied saying XFR will overclock for you...
I don't think it's that simple. I think in a real application the MMU is going to get overloaded with so many cache misses happening as threads move back and forth from one CCX to another that it ends up affecting it far more than just another 80ns wait here and there over Broadwell.
Also...
The likely reason there will be non-SMT chips I think is for TDP reasons.
The most poorly binned chips may be too high TDP with SMT enabled, so it's not that it's defective but it will be disabled and them sold as cheaper CPUs.
A 1700 with 1 CCX disabled as a 4+0 is going to be better in 99%+ of games than any 2+2 or even 3+3.
That really ticks me off. I don't want to spend more than I need to for twice the cores over a 1400 or 1500X just to have to disable cores and restart my computer to get the most out of some...
Even if F1 and other games using the engine correctly identified 8 cores with SMT, that doesn't make it "aware of its topology"
Only if an application identifies that it has 2 L3 caches per set of 4 cores and significant latency to cross them is it actually aware of the topology.
Hm.
So they...
http://www.anandtech.com/show/11202/amd-announces-ryzen-5-april-11th
The 4 core is 2+2... 2 cores per CCX. But 16MB cache on the 1500X. Still.. this is pretty bad news.
The 4 core is going to be worse gaming performance than disabling a CCX on a 1700...
That's really freaking stupid.
There is a significant difference in heat when you get to 3.9Ghz on 1.3v versus 1.4v...
And SMT is going to be disabled on R3 chips, I'm sure. Those just don't come out until H2 of this year.
Sure. I'd have happily paid more than $195 if it was 3.6/4.0 stock with SMT, though.
I just wanted a...
Or rather, they should have just disabled the SMT on the 1400 and increased the frequency and sold them as a higher clock 4c/4t for less and had the 1500X the only 4 core with SMT.
I'm really disappointed that the 1500X isn't 3.6/4.0ghz though... 3.5/3.7 is pretty low.
I'm guessing many CPUs...
Thanks for the correction.
But it does not change that that other article looncraz as referring to was just a fix to have it correctly identify which threads are the second threads on a core, and not an update to scheduling to better optimize for the dual CCX structure.
I think you misread/misheard.
The only update for Linux, which happened right away, was to correctly assign SMT threads.
-znver1 is relying upon the btver1 scheduler model. Btver1 is for AMD's Bobcat.
People are finding using the Haswell scheduler model improves performance 5-10% in Linux, but...
For many threaded tasks in games, they don't care how many cores there are. They spawn a thread and the OS scheduler may stack it with another large thread, or it may not.
But for easily parallel tasks like physics, yeah those are things that they need to be aware of the thread count to spawn...
Linux didn't adjust their scheduler to account for the "2x4 core" design yet, dude.
It's expected to happen in the upcoming months, and programmers have said it's on their list, but it was not "fixed in less than a week".
What's wrong with it is the vast majority of games (talking close to 100%, not simply over 50%), don't do their own User Mode Scheduling.
Expecting these tens of thousands of games to suddenly get patched to implement that, many of which are made on an old engine they didn't make, is freaking...
Some of those games like Witcher 3 are known to run much faster with faster RAM. Fallout 4 is another one.
It's just bad programming that leaves them hitting memory a lot.
No VIDEO GAME should be RAM speed limited like that. It take poor programming to make it happen.
Windows7 scheduler does not really work any better. Performance increases in Windows7 over 10 are likely for the same reason some games run better in Win7 for Kabylake than they do in win10.
Windows7 does not understand the architecture any better. It does not better attempt to keep an...
AMD engineers have to understand this scheduling problem and how this is predominately a Windows problem and not application problem...
So why does the marketing department and customer service give another answer? Has MS said "your problem not ours" and AMD doesn't want to hurt their...
Ok.. the forum won't let me do a quote. But in regards to Mafia III and it seemingly already being Ryzen optimized:
It's probably one of the very few that does its own thread scheduling instead of relying on the OS scheduler.
And as for why Ryzen suddenly does better in games it seemed CPU...
I've been watching this discussion for a long time but couldn't bother to log in. But people keep glossing over something over and over that I'm surprised no one has pointed out:
The reason why disabling SMT seems to improve performance in Windows10 almost surely has to do with increasing the...
That is a really ugly case.
I'm looking for a motherboard that can fit in my 500R and has 3 slots between the 16x slots.
Only one I found is http://www.newegg.com/Product/Produc...82E16813157322
I think it came out a lot dustier looking from the flash.
My fans are clear of dust, it's just sitting in some places that don't matter. I'm going to clean it when I upgrade, though!
Hm anyway I looked at the board.
Yeah the PCI slot looks high up like I needed, but it's only a 2 space gap...
I have an MSI Lightning 7970 with the Artic Accelero cooler. This takes up pretty much 3 slots.
I want to add another similar card. Probably a http://www.newegg.com/Product/Produc...82E16814202001 and I'll probably get the same cooler for it. That means I need 7 slots of clearance.
I have...
