Steamroller core

I think I will wait for the benches...

me too...( but i love speculation XD )

i am under impression that JAGUAR might handle Multi-threaded Floating P. better than SR

:thumbsup: I hate proprietary binary formats; I have experience being burned by a bug with SBPF a few years back. Even OA can be a pain due to version compatibilities...but at least you have a chance of figuring out if the problem is in the database vs. the tool because you can get OA source code and access to the OA bug database.

Sorry OP for the OT
Trying to move from good 'ol LEF/DEF to OA has been... interesting, but at least there is some visibility as far as what exactly is going on.

With Milkyway, we pretty much have to watch out (and separately and explicitly set) all the various flags because even Synopsys doesn't guarantee that all the settings will be remembered (which is the whole friggin' point of the dang binary dbase!). Also, have sometimes run into odd corruption issue with the dbase, especially when using it with IC Manage.

4 issue wide decoder per core? Welcome back to 2006, AMD.

How funny that the company that delivers like clockwork has not even officially unveiled their next-gen details but yet the company that doesn't has already done it for their next-next gen.

I agree, but I think part of it has to do with credibility. We all KNOW Intel is going to deliver with Haswell (even though we don't know), because Intel has delivered "like clockwork" for quite some time now.

AMD has been a disaster, so they are trying to show the world (read:investors, clients) that they have a plan, they are executing the plan, and that the plan is the bees knees.

Honestly, SR does sound pretty good, though it is disappointing that they aren't planning on fixing L3 (though as mentioned in TFA it makes sense). I think the automatically adjusting L2 cache sounds awesome and is particularly exciting.

Following up on the Steamroller coverage, this vrzone article today sprinkles in some "inside sources" opinions:

AMD Pushes Steamroller and Excavator Forward, Bullish about Performance Increases

including this quote:

According to Mark Papermaster, the improvements should yield up to 30% performance increase, but our sources inside the company beg to differ.

"Steamroller is not Bulldozer Enhanced. F*** no. The layout might look the same but our LEGO blocks are completely different. When all is said and done we should get 45% improvement and this goes to show how the Bulldozer was f***** design. This is all what Bulldozer was supposed to be."

I just hope this is for real, and not just an inside engineer "talking trash", as competition is always good for us.

 

[ShintaiDK]

Sounds like utter BS again. Remember "dancing in the aisles"?

Wait a moment,the author of that article is no other than Theo "reverse MUltithreading" Valich? The author of the other VR-zone gem ,"Piledriver canceled-AMD will put the hope on Steamroller", was Mr. Novakovic. I would disregard vr-zone from now on. They are just making things up I'm afraid. 45% performance improvement? In what exactly? Just dreams I'm afraid.

 

[NTMBK]

VR-Zone make an interesting point in comparing Steamroller not to the desktop Intel platform, but the server. Given Intel's tendency of massively delaying the server/enthusiast versions of their new architectures (see: SB-E), AMD's "time lag" doesn't look quite so bad. Don't forget, Bulldozer is just an Opteron in disguise. Steamroller won't be going up against Haswell, it will be going up against IB-E- or maybe even SB-E, depending on just how bad Intel's execution is this time. (IB-E is currently scheduled for Q3 2013. http://www.tomshardware.co.uk/Ivy_Bridge-E-LGA_2011-X79-cpu-mobo,news-39375.html ) While to us Steamroller is looking like it will still lag well behind Haswell, it might compete very nicely against IB-E.

I hadn't caught that, glad you did and that you took the time to mention it so a few more of us would be clued in :thumbsup:

Yeah these guys just literally make up stuff for the money. Anonymous sources indeed. Isn't that the ultimate CYA when making up stories?

Extraordinary claims require extraordinary proof.

As much as I wish anything from AMD was competitive (because competition drives innovation), I have very little faith in AMD pulling another "Phenom 2"-like release. Bulldozer was a big disappointment, Vishera chips haven't even been released yet, and now AMD is touting Steamroller? As other posters have said, Vishera might end up being another disappointment and with Steamroller being one to two years away from release (in realistic time frames), all I can say is....bring on Haswell. Heck, bring on Ivy Bridge-E.

Actually steamroller should be released in less than a year with Kaveri. I hope they succeed, so they at least get some credibility with the 'execution execution execution" strategy. (hoping the 28nm will be alot better than the 'failed' 32nm node).

 

[inf64]

Kaveri is based on SR core... So we will know how fast or slow SR is when Kaveri APU launches.

Come on, do you really think AMD went to all the trouble and expense of developing the Piledriver core just to sell it for 6-9 months?

That would be an incredible waste of shareholder money if it turns out to be the case.

Given what we know of AMD's execution, implying stuff will ship in H1 and you are lucky to be able to buy it from newegg by Christmas in H2, I will be pleasantly surprised if any of us can buy a steamroller-based SKU from newegg before December 2013. :|

 

[Homeles]

Llano and Trinity were both released in June, IIRC.

Still, it's a new process this time around. I wouldn't expect the gap to be as short this time.

 

[Haserath]

Maybe. Piledriver is the quick fix to Bulldozer, and maybe they also wanted to test out the cyclos mesh first before SR.

Might as well deliver a checkpoint of your work every now and then for some extra cash instead of having a long developement cycle with nothing in between.

If Steamroller is really as good as AMD says it will be, they'll make more money from SR by releasing it early than keeping PD out longer, wouldn't you say? And when was the last time AMD released early? Might instill some confidence that they are back on track schedule wise at least.

No, No. It's "Steamroller will be 50% faster than Haswell!"

Anyone know if SR will have AVX2?

Win!

It's possible but unlikely.

 

[IntelUser2000]

I believe the claim, but I bet its for servers. With Abu Dhabi's gain(I assume maybe 10-15% with half due to IPC and rest clocks) plus this, it would end up in the realm of Xeon E5.

45%
-25% more cores
-IPC and clocks

But that's not what they will be facing. They'll be going against Ivy Bridge EP, which for all intents and purposes is yet another big gain in servers(despite the fact that its not very compelling for desktops), keeping the big gap yet again, if not bigger.

Ivy Bridge EP has at least 25% more cores, with improved IPC, and slightly higher clocks, leading up to about 40% gain over Sandy Bridge E5. But some leaks indicate it may have 50% more cores than Sandy Bridge EP, which with clocks and IPC may end up at 60%.

 

[NostaSeronx]

No, No. It's "Steamroller will be 50% faster than Haswell!"

Steamroller will have AVX2 and an extension of XOP.

Post-post edit: Kaveri is coming out Q3 2013 with the 1H of 2013 getting a new stepping of Trinity. The new stepping only includes higher clocks for the CPU and GPU, and no architecture tweaks or bug fixes.

I'd be tempted to propose they might ship a few select Kaveri SKUs ahead of the rest of the Steamroller product lines. However, looking at the last few generations and even to the latest Trinity SKUs I'd say your spot on that they probably won't appear in any quantity until Q4 '13.
