Intel Says AMD EPYC Processors "Glued-together" in Official Slide Deck

[seinthebear]

What is that BS about gaming power consumption of Ryzen??? Of course it has lower power consumption because of the limits of the Ryzen architecture it can't be properly utilized and provides sub par performance to an "only" 4 core chip...Actually Ryzen's single core performance is sh..t and a lot of applications still relies on lightly threaded performance where high single core performance is needed. Overclockability of Ryzen is mostly presented as 4 GHz as a matter of course, but that's not the case, lot of Ryzens are really rubbish binned and some can't even do 3.8 GHz.

Are you sure about that bud? https://i.imgur.com/ESluXlW.png

Meh, nothing new from Intel.
It’s been a while since they stooped so low though, but then again, it's been a while since AMD was relevant.

Luckily this time around, nobody is eating the deliciously creamy BS, that Intel is trying to shovel on everyone’s racks. AMD has already so many partners for EPYC it’s no wonder Intel is shitting itself.

I think most people behind systems using Xeon processors, hopefully Epyc also in the near future, know much more than us about processors and stuff. Much much more.

You would be surprised. Most senior leadership roles are filled by those who scaled middle management hell. By the time they are making executive decisions on this type of shit their only hope is listening to their direct reports. Who as well probably don't look at most data behind power point presentations. So yes, this type of tactic is very effective against uninformed leaders (most of them all are).

Intel used MCM then, so what. This is part of reason I haven't used intel since p4 days, childish bs.

They are just trying to stirrup FUD

Exactly. Nobody ever got fired for buying intel...

That being said, alot of those types of CIOs are turning to the cloud companies or contractors like DELL proserv to avoid the cost and headache of running everything in house/ making decisions for themselves, and those are usually pretty nimble (first to adopt SSD's, regular replacement cycles etc.)

Taking everything technical out of this discussion, from a marketing (internal) point of view there is a fundamental truth to the comments here.
In marketing, you never deride the competition unless you believe they are a threat. It's that simple. Or, if you're the underdog, trying to prove your worth. Industry leaders do not NEED to prove their worth. So whether or not Intel's point is valid isn't that relevant. It's that they feel the need to 'reassure' their base that Intel is still superior.

BINGO!

 

[The Stein]

Hey, that sounds like the Pentium D!

Or the Core2 Quad series.

Doesn't help Intel is talking deal even though throughout this year they've made an asston of terrible decisions.

They wouldn't need to reassure their base if they didn't consider what AMD has been doing to be a threat though. Intel is just downplaying it and it's not going to destroy Intel but, Intel is in this position where they have the most to lose. The question is, how much? This is preemptive damage control.

On die mesh is better for low latency. Intel is right about that and they are playing with that because it is the only advantage they have now. There are many applications in which EPYC can provide great performance, even better than Intel, for half the price. But latency critical real time cloud backend tasks run best on the Skylake-EP, there is no denying that.

There is room for both AMD and Intel in the data center of tomorrow. Depends, what you want to do.

 

[Vya Domus]

But latency critical real time cloud backend tasks run best on the Skylake-EP, there is no denying that.

Or you could code in a smart way and avoid that , not much of an advantage after all. As I understand there should be more or less the same latency core-to-core to any of the CCX modules from any of the 4 dies. Therefore whatever method you find for reducing latency should be scalable.

 

[Jordan M Eilbert]

Glued together? So much unlike the lid of the i9 CPUs then with their massive thermal leak due to your choice to cheap out on crappy thermal compound between core and lid?

There are things that are really really hard to code better, and very sensitive to hardware latency. Minimum time to serve a web client from data base for example is one of them.

http://www.anandtech.com/show/11544/intel-skylake-ep-vs-amd-epyc-7000-cpu-battle-of-the-decade/18

That is one example of such an oddball latency critical use cases.

Always, when you need to go outside of the die in MCM, you will get latency disadvantage.

Intel needs a laxative. They are so full of shit.

You do realize that this is the worst case scenario for AMD, like the torture tests for i9 showing how bad thermals can get?

As expected, the EPYC 7601 can not deliver high database performance out of the box. A small database that can be mostly cached in the L3-cache is the worst case scenario for EPYC. That said, there are quite a few tuning opportunities on EPYC. According to AMD, if you enable Memory Interleaving, performance should rise a bit (+10-15%?). Unfortunately, a few days before our deadline our connection to the BMC failed, so we could not try it out. In a later article, we will go deeper into specific tuning for both platforms and test additional database systems.

Typically when high response times were reported, this indicated low single threaded performance. However for EPYC this is not the case. We tested with a database that is quite a bit larger than the 8 MB L3-cache, and the high response time is probably a result of the L3-cache latency.

 

[Jism]

Mweh. AMD was the first with the X2 processor that would actually put 2 dies together. Intel follows up with a CPU that glues 2 dies together simular as Epyc / Ryzen is or was.

The main goal was to cut / save costs from AMD, put more smaller cores together, link them with a high bandwidth bus and they succeeded. Now intel is whining about a glued design that actually does a pretty good job in COMPETING for a much better price.

Your quote says "We tested with a database that is quite a bit larger than the 8 MB L3-cache, and the high response time is probably a result of the L3-cache latency."
This is not the worst case scenario, unless you claim most data bases are smaller than that.

EPYC is not best for all use cases, nor do AMD claim so. Get over it.

 

[TheGuruStud]

The salty tears from intel are so satisfying. I wonder how many are going to quit after getting yelled at by execs for failing the company LOL. It must be getting pretty hostile over there.

 

[Bansaku]

The last time I upgraded with Intel was back in 2012, like the vast majority of us. Sorry Intel, AMD is leading the charge this round! Say what you will about glued together CPUs; They are kicking your ass!!

 

[TheoneandonlyMrK]

Why focus on the bullshit of a pr piece.

The details were far more comedy worthy with other sites focusing on the stuff that matters , like

Intel's new 28C/56T CPU costs $8719, uses 670W of power Intel's new beast of a CPU uses up to 670W, which is insanity

Thats tweaktowns take on it

Be very interesting this battle as id imagine Amds Epyc won't get anywhere near that power use.

Or cost.

And its especially laughable when intel are stating customers have to stay with Intel for Vm support.

THE WHOLE SYSTEM USES 670W NOT THE CPU. God bless read the reviews. Tweaktown and their clickbait misinformation at ads needs to fix its garbage. They are worse than CNN.

I do hope you're right , and believe so , I was so taken back by it i couldn't think through the nonsense.

That's still a lot.

I am I actually read the original toms hardware review that was stolen from.

That's still a lot.

That isn't a lot for a server...

 

[justimber]

Intel does really know how to use glue to call AMD for using it. lol

 

[Rahmat Sofyan]

this guy, has really good opinion.. deleted for some reason, but somebody already ss it..


overall, as a customer can not more really happy how great the competition today.


But, seriously.. "glued" ? , so ridicoulus.. can intel proofing it ?
