nice one
Werd!
Excavator looks to be twice as high on Amd's chart ;)
30% increase over steamroller! Lol
What process node will be available by then? 20nm?
Maybe the increase will be big because it will be an APU by then!
Should we include jaguar/hondo? Eh maybe not lol
it's too quite on this subject matter ?!?!?!
has Two decoders 4 way to each core ? (unknown if true)
Has increased instruction cache size (size unknown)
most likely will still have 16Kbytes 4 way cores
Less L2 cache said to be 512Kbytes
Steamroller will be successful
I'm predicting an 8 core APU with all thr die spacr savings of 28nm and dynamic library's
you're right in that we wont see any improvements from 32nmSOI->28Cmos in terms of die space or power consumption but where we will see gains is cost. If I remember correctly SOI is something like 20-30% more expensive, with luck AMD will be able to give us a good dual module apu to compete with the pentiums in both desktop and laptop. I really think that trinity would make an amazing ultrabook processor, sadly hp make the only AMD 'sleekbook' at 15"(!).
But just like any new process tech on a processor for AMD, it will probably take time to get right. So 28nm bulk may be just as leaky at first as 32nm SOI has been so far.
I post this in the other thread too.

Steamroller brings no significant reduction in L2/L3 cache latencies. According to AMD, they’ve isolated the reason for the unusually high L3 latency in the Bulldozer architecture, however fixing it isn’t a top priority. Given that most consumers (read: notebooks) will only see L3-less processors (e.g. Llano, Trinity), and many server workloads are less sensitive to latency, AMD’s stance makes sense.
so L3 cache has some problem ?
L3 has every time higher latencies than others caches, it depends at architecture.
seems like kaveri will be a nice step in both cpu and gpu performance
I heard on techreport podcast that amd is going to release a 19w quad core trinity for ultrathin market.
Steamroller "bdver3" Compiler Support:

Interesting thing like this:
Quote:
The bdver3 contains three pipelined FP units and two integer units. Fetching and decoding logic is different from previous fam15 processors...
No steamroller? No kaveri? R u serious? Amd is :banana::banana::banana::banana:ed
Game over AMD. Seems like next 5 quarters of big money loss. In their current financial situation there is no hope for them.
Tap tap tap - SGS 2
Kabini with Jaguar looks great, Im thinking. Vishera all next year? If AMD will be lucky, maybe at end of 2013 is SR possible. In worse case it could be sometimes in H1 2014. So...we will see maybe higher Vishera models in 2013.
possible with vishera on 22nm node?
No, i think no....Im meaning, we will see maybe 8320/8350 in 95W version later and new FX-8370 (maybe 8390) in 2013
Something is odd with that chart. I was under the impression that Richland was using Steamroller cores and is based on the 28nm manufacturing process.
you are wrong, Richland is in old roadmap still for FM2 and with Piledriver cores - it is "Trinity 2.0" platform in some roadmap. Everything on 28nm node (Kaveri/bdver3) is delayed to 2014, GloFo 28nm is not ready for mass production. Steamroller is 28nm architecture, is delayed too.
Yup it's gonna be a long long 2013 for amd
What's a "dumb shrink"? They don't simply press the shrink button when a process is finished and working chips comes out the oven. There are enormous challenges to it and lots of things needs to be remade - it's costly and extremely time consuming, think not of several months rather several quarters. Just shrinking to a new process without doing any sorts of improvements doesn't make sense.
I recall one of the AMD executives (i can't find the quote anymore) making a statement during an interview and saying something to the effect that the "piledriver core of 2013 will not be the same piledriver core of the initial release".
Maybe they have further enhancements that will occur in 2013 to piledriver before shifting to SR cores in 2014.
I think it's just a clock bump. With SR finished there is no point in tweaking PD core and I doubt they can get much more than what we have now anyway. PD is a solid bump in performance Vs Bulldozer,I just don't think it can hold up to Haswell next year,that's all.
Is Radeon 2.0 = GCN?
And to get things tested so the new architecture can be designed better. Its why new node + new arch atr the same time almost always have problems of some sort. Just look at Phenom I and Bulldozer. All fixed with subsequent core tweaks because of too many issues from trying too much at once. Steamroller looks great on paper, I just hope it executes well since it is a shink and somewhat of a core re-design again. Granted, at least its not a 100% architecture change so it has more hope than Bulldozer did.
everywhere I've looked says richland is 28nm APU of piledriver. it's trinity on half node (yes AMD is doing half node with APU's)
Kaveri is steamroller apu on 28nm. Steamroller was already stated to be in tapped out and sampling off 28nm.
richland it self looks to be taken off some older road maps it was on them with Krishna and Wichita. Those are no long their and Brazo 2.0 in both their places.
This makes no sense. How can AMD release bdver3 GCC support which implies massive changes to decoders and stuff, and then cancel it? Wouldn't GCC support for Steamroller mean that it's already done? Are they just going to throw the chip away?
Also, what about rumors of PS4 using steamroller? I don't understand. Does Sony need so many Steamroller CPUs that AMD can't provide enough for everyone and has to use a tweaked 32nm PD 2.0 for desktop?
If I well understand, Richland is Trinity + HSA feature and Bolton PCH. Graphic parts is maybe the same.
explains slide a little more maybe
http://wccftech.com/amd-richland-apu...d-8000-series/
hopefully kabini and tamesh on 28nm do well
Now, Trinity: 4 core x 3.8ghz x 8 + 6 SIMD x 64 x 0,8Ghz x 2 = 736 GFLOPSQuote:

Yeah, slide is good enough for me. Havent seen that one earlier.
It makes sense that no major changes will happen until 28nm, so richland being PD cores and vliw4 doesn't suprise me. I did read about trinity 2.0 in the summer, but was hardly mentioned again, but if trinity 2.0 = richland, that makes a lot of sense.
this is getting confusing, whats the actual changes for richland compared to trinity? im reading that its just trinity with CGN.
Well trinity with GCN would be great for a refresh....Some improvement in memory controller would be welcomed also :)
in very old roadmap was Richland APU, it was Dual Core + VLIW-4 196 SP?s, originally Trinity for notebooks!
http://www.abload.de/img/cdb3a587-856e-4043-87ojbqe.jpg
But this is "new Richland", There are two possibilies about it:
1. Piledriver CPU + VliW-4 GPU on 32nm node, higher clocks, nothing more
2. Whole Trinity (Piledriver/VLIW-4) on 28nm node
I bet first is right!

More recently, SemiAccurate?s moles have come back and said that Kaveri has slipped yet again to 2014 if it is still alive. Big if. That would put the chip 18 months late best case, and then you have to ask yourself why not just skip it? Time will tell what happens, but one thing that is not in question is if there will be an updated APU in 2013. That answer is definitely no, Intel has the game all to itself next year.
Time will tell if any of the rumors are true or false.

Thanks to cal_guy on B3DQuote:
2012-11-14 23:42:21 < Skyler_> amd just sent me a Steamroller CPU.
so they do have ES out already? :P
is this real?
that means in 2013 we have steamroller :)
richland is 32nm, Kaveri 28nm, right?
Possibly cancelled:
http://semiaccurate.com/2012/11/19/a...and-excavator/
Do not we know for half a year, that is the last AMD High-end desktop cpu ever is Vishera? - Yes, we know already.
what?
OBR is "special" guy. Best avoided.
On the topic of "Kaveri cancelled" BS ,SA retracted the story since AMD denied the big cores are cancelled and stated they are still on track.
i wonder how many clicks they got from that
Of course AMD denied it, what else should they do? SA are obligated to print the AMDs denial comment - doesn't make it true.
So if Amd came out with an 8 core FX chip with steamroller what r the projected % gains from say an fx-8350?
If I recall steamroller is more of an ipc improvement
We won't be seeing FX based on SR core next year. Maybe 2014. Best case scenario is APU Kaveri,if it launches next year.
He is also banned here,but you know that :). Even a broken clock shows a correct time 2x a day,it doesn't mean it's OK to always check for time on it :).
He wasn't banned for misinformation, but for being an ass.
Has he been way off lately on AMD-related topics? Afaik, most of the number he posted were at least close to accurate.
He saw one roadmap that has no new FX in 2013 and proclaimed Vishera is the last high perf. desktop CPU. He reposted stuff(Vishera ES) from a Chinese forum/site and claimed he leaked it. And he has a pathological hatred for AMD. That's not a reliable source IMO,that's an attention whore :) (pardon my French).
Oh I forgot to add: he claimed that HD48xx series won't have 800SPs but 480SP. He failed there too. And that blog post of his is gone,of course.
sorry for my english, i am german. i thought blame us is deceive us :) corrected
repman - http://www.3dcenter.org/artikel/laun...r-rechenkernen
From six FX-8350 reviews has FX-8350 higher power draw in four! table : Volllast (Syst.) down on page
So of all the things he wrote, there's now one or two that are incorrect. That's not very much of a basis to disregard everything he writes by principle.
his attitude towards amd just shows that he's a douchebag. He doesn't post anything but amd stuff. His posts about amd stock just shows you that his blog has only one motive.
regardless can we not talk about anymore?
this is derailing the thread
back on topic.
ah yes back to steamroller.
I was thinking about this module only has one fetch for two cores
A normal dual core would technically have two fetches for the two cores one for each core.
Can the front end even give enough data for two decoders from one fetch, it seems like it would be the major bottleneck?
hopefully there is a amd fanboy on the JP Morgan finacial team and there showing him a steamroller chip and hes like daaaaaaaamn intel killa
lol
No. SR has two decodes, one fetch.
Page 12
Well what I meant it addresses the front end bottleneck(and fetch is in front end). And they optimized the fetch stage Vs BD/PD,it's more efficient. But yeah,there is one fetch per module as before.
It's obvious it's decoding stage since that's what AMD doubled ;). But they did optimize the fetching stage too,it's more power efficient now and has a micro-op queue -this is a new feature Vs BD/PD cores .
wow 28nm is far out, well at least its on the road map now and not in lala land
Posted a while ago. Still true?
http://www.theinquirer.net/inquirer/...or-steamrollerQuote:
CHIP DESIGNER AMD has said that its upcoming Vishera chip will not be the last to use Socket AM3+.
Nobody knows,AMD included :D. They have changed their roadmaps so many times in the last few years that making any predictions on the socket longevity front is useless.
by the time they release a new desktop part they will be forced to have a new socket cause am3+ will be so old by then
did anyone read this ?Quote:
"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."

Yes it was posted already on this forum. Smells like bs to me.

This is about kabini....looks promising
