AMD Ryzen (Summit Ridge) Benchmarks Thread (use new thread)

[raghu78]

Looks like AMD did a bit of "sandbagging" with the 40% ST IPC claim .
If the 4C/8T part really gets a 150$ price tag, locked or unlocked, there is no way intel can price an unlocked i3 Skylake at 150+$. Nobody sane would buy it.

AMD followed the age old promise of underpromise and overdeliver. When you are so far behind your competitor and have been for such a long time its prudent to not make bombastic statements or predictions. A clean sheet design comes with its own set of risks and challenges. So its good to see that AMD made very modest claims but have exceeded it. When AMD revealed Zen's architectural details about a few months back it was very clear this architecture was going to be Broadwell class definitely. Now it definitely looks to be the case.

I think the best maybe yet to come. I think AMD is saving the most impressive part for launch.

If we consider that Blender is used in a lot studios, Zen could be a commercial success among the professional users.

Also, it's true that this is not the total picture of Zen performances, but I think AMD (AKA, Lisa Su) want to hide some ace.

Interesting clockspeed discussion. It seems that consensus has shifted to 3.4 GHz base clock. But if you watch the AMD event at 27:20 https://youtu.be/4DEfj2MRLtA?t=1641

From the context I infer that the 3.4 GHz is the base clock for the "low" end Ryzen and there will be another 8 core SKU with even higher base clocks. On the screen there is only 8c/16t 3.4 GHz+ 20MB L2+L3 cache. But 4/6 core chips won't have that kind of cache so I assume that 3.4 GHz+ also refers only to 8 core SKUs.

What she said is that

"our Ryzen processor will have base frequency of 3.4 or up. "

Not "and up" but "or up". Keyword "or"

So they are sure they can get that base but perhaps more. No implications about low end or high end.

Actually I think 8c is what she talks about all the time as I asume that's what will compete with i7. 4c and 6c will be harvested from same die. So 8c is where the meat is.

If you followed AMD's FX CPUs the 4 and 6 core chips had higher base and turbo clocks than the 8 core . The logic is simple. Clocks are directly related to TDP. Having more power per core allows AMD to target higher frequencies for base and turbo on 4 core and 6 core chips. btw I think its likely there are two 8C/16T SKUs with the slower chip at 3.4 Ghz base clock . The faster chip could very well be clocked at 3.6 Ghz base. I am keen to know what are the max Turbo clock speeds. If they are 4+ Ghz then its going to be a very good product.

I agree that it's a bit ambiguos. We could probably parse and argue those few sentences until Ryzen is launched. For example if she wasn't sure would she instead say "our Ryzen processor will have base frequency of 3.4 or maybe higher. "

I just interprete that they will initially launch two 8 core chips. Lower tier having 3.4 baseclock. The way she said it somehow gave me the impression. Like she knows something we don't. But we'll see.

Oh yes. I definetly agree that 4/6 cores will have even higher base clocks. I didn't mean to imply that they wouldn't.

 

[sirmo]

Did anyone get the vibe that AMD made a big deal out of the Neural Network Smart Branch predictor? Do we know how long Ryzen's pipeline is? The way I see it, Lisa mentioned 25% of the improvement to the IPC uplift comes directly from the branch prediction improvement. It makes me think that they seriously invested in the branch prediction to mitigate a long pipeline. Which could mean that this thing might clock pretty well.

I was browsing r/amd when suddenly...

https://www.reddit.com/r/Amd/comments/5ijxit/rumor_biggest_french_hw_retailers_cm_about/
Hi r/AMD,

I think you could find it interresting : this morning, @hardedfr, community manager at @LDLC (the biggest french hardware retailer) post the following statement about ryzen on twitter.

Here's a basic translation :

@hardedfr : Then I came across a benchmark involving a core i7-6950k and... the brand new AMD high-end Ryzen

@LarsVenciental : and?

@hardedfr : really not bad at all

@LarsVanCiental : does it heat?

@hardedfr : At the moment, cooled by the (pretty) AMD stock ventirad, it's pretty good

@LarsVanCiental : So it's a good news for me and my commit

@hardedfr : Yes. Everything will be shown at CES. And it's LDLC who's in charge for installing a big rig for the event.

edit : edited for typos

Just looked it up, CES 2017 is January 3-8, so we might get something in between New Horizon and launch.

Hope that rumor is true, because my brain is short circuiting too at the thought of having to wait this much until launch, just like some other people here

 

[CHADBOGA]

AMD is not shunned by most people because of IPC. They have lower IPC, higher power usage, and many other things. Those things mean little to nothing to most people, because most people have no idea about the tech they buy.

AMD had over 50% of retail sales during the heyday of the K8, of course their current dire predicament is due to low IPC/performance.

AMD's sales success is in direction relation to their performance competiveness.

If the promise of Zen holds up, they only will need to price their CPU's at 75 to 80% of an Intel equivalent and they will sell all they can make.

Nice find, thanks for posting. That Broadwell-E monster is usually running at around 3Ghz, so Ryzen at ~3.8Ghz should do the job I guess .
BTW January 3rd is in just over 2 weeks from now, not that far away.

In the server market, yes. They simply couldn't make enough to reach 50+% overall. That shouldn't be a problem this time, so long as the demand is there.

 

[Thunder 57]

I don't know the situation of INTEL, but for AMD, i have numbers for jaguar regarding active transistors at a time.

Even with power virus, we are in the range of 15% of the total transistors not clock gated in jaguar. And 10% the actual value in full load with not power virus load. This means that most transistors each instant are in clock gate and are leaking.

But leakage on 14nm is 1/6 of 28nm! Do you understand why i am so confident in what i am saying?

I understand why you are confident, but I don't necessarily agree with you. Sorry if you have already been asked, but what kind of base/turbo frequencies would you expect for 4/6/8C Zen, assuming 95W TDP?

 

[lifeblood]

There are some slight rumors rumbling that should be taken with a grain of salt that prices will be as follows:
$499 Top binned fully unlocked 8c/16t Zen
$349 8c/16t Zen
$249 6c/12t Zen
$149 4c/8t Zen

I don't think these numbers can be accurate. In the ballpark maybe. We (and they) know base is at 3.4 minimum, but it sounds like they're still trying to get it higher, especially boost clocks as they didn't even allow boost in the demo. Obviously the more performance they squeeze out the higher the prices go.

I bet they don't release until the end of Q1 as they want to get the absolute best clocks they can possibly get. Assuming performance is as good as they claim, imagine the marketing monster a 3.5 base with 4.0 boost CPU would be. That magic number, 4.0, would add at least 10% to the sellable price of the CPU as people love nice round numbers.

Polaris and console APU's gave them some breathing room, but they need RyZen to really make a splash to truly be back on the road to recovery.

Oh man, does this mean classic AMD trickery: buy the 4c, unlock to 6c, save some cash and get pimp performance? Giggidy!

 

[moonbogg]

My shock is slightly lessening. I am starting to slowly wrap my mind around AMD being good again. Bottom line for me is that if Zen OC's well enough then I'm buying one. 30% IPC over Sandy plus 2 more cores isn't a bad upgrade. I wanted an 8 core Skylake rig but the chip will cost over a grand, so Zen it is.

So, I'm still struggling though. Coming to grips with AMD being awesome again is like realizing that after 37 years I discovered I am actually a woman, or something equally shocking. That's shocking huh. If true would be shocking.

No no, its like if PINTO cars were suddenly a thing again and the first new one out was faster than a Ferrari. Yep, like that.

 

[CHADBOGA]

In the server market, yes. They simply couldn't make enough to reach 50+% overall.

When I say "Retail Market", I am talking about those that are sold in outlets like Best Buy, Newegg etc, not the likes of Dell.

And this was achieved back in the day.

Their inability to supply sufficient quantities to the whole market was exposed only when Dell started to sell them.

 

[sirmo]

Almost think AMD does it on purpose (not lasering off binned parts). Will never forget buying a Phenom II 720 X3, unlocking the 4th core and OCing it to 3.6Ghz.. All that for like $130 something.. crazy bargain.

Intel per core performance means Intel per core prices. Ironically Zen bargain hunters need to hope AMD doesn't do too well here.

If AMD was remotely smart in the past few years and learned from the best (read: Apple) they should have know that margins are far more important than raw marketshare.

Summit Ridge will split the difference as they try for higher margins than in the past while chasing after higher marketshare where it counts. The top-end Summit Ridge will go after Intel HEDT buyers with better-than-6900k pricing with better-than-6900k performance (er, we think). $500 makes sense here. Though we may see prices as high as $800-$900 at launch if we get NewEgg effect . . .

 

[Ajay]

Parasistic losses are accounted anyway when they say same energy per cycle, Zen with its static parameters will consume the same as XV with its own characteristic and this with 40% more instructions executed each cycle, the terms are self explanatory and there s a slide to better understand :

So, obviously, big drop with smaller process + FinFet. Didn't follow the whole discussion, sorry.

I am predicting some more expensive [golden sample] high bin parts at like 3.6Ghz base clock. But I think the base 3.4Ghz 8c/16t part will be highly competitive. As low as $399.

 

[moonbogg]

Imagine the chaos if this thing OC'd nicely to 4.6 and came in at under $600? LOLz abound.

If top binned Ryzen matches top BW-E, AMD would be silly not to charge $700-$800 (basically a brand discount). Time to pay shareholders. Other SKUs in the line up can cover mid to low pricing tiers. Also, higher margin can pay for marketing campaigns, which AMD will need to expand Zen's reach into commodity biz and consumer markets (if they are even going there this round). AMD might just be targeting knowledgeable professional/gaming market + servers.

Not funny, really - not for the long term health of the company. Lolz all around would be getting 4.4 GHz OC from the second tier bin for $600. And I'm being serious.
You would be on the same page if you want a competitive Zen+, Zen++, etc. Now if Intel drops pricing eventually, then everything changes. I don't see Intel dropping prices significantly in the short run - these are high margin parts for Intel (and that's the only reason they exist).

I don't see Intel keeping the 6900k @ $1100 though. They'll drop it to $800-$900 so AMD will have to slide in underneath that to really turn heads.

I thought Intel's problem with the 6900K is that they didn't want to tick off their server customers who are paying well above $1,100 for what exactly, I am unsure.

What is the difference between a 6900K and the server equivalent?
