Exactly! If the implementation shown in the video was different from what Exynos Octa uses, Samsung would not upload video in their official channel and also mention Exynos OCTA in title and description. :cowboy:
[Xperia Z General] :
Really? Have you actually seen the video man? I thought you were just acting previously, now I can clearly see that you are trolling.

This is a test chip even

without a GPU

. It's a 3x A7 and 2x A15.

Do you think this is the implementation of Exynos Octa? So, according to you Exynos Octa will launch without a GPU and total 5 cores??
[Xperia Z General] randomuseresato:
So you mean Samsung is dumb to upload that video in their official channel. Seems like you know more about Exynos Octa than Samsung :D

Also you are contradicting your own statements. You asking me to check ARM page but are refuting a video posted by Samsung explaining how ARM big.Little works. :p So according to you, either ARM and Samsung are both fools or I am.

This video is not "shot" by Samsung fine, can you post a link where SAMSUNG has said that Exynos octa can use all 8 cores ? Don't tell me to "check ARM page" again. The documentation explains what may be possible, but the video shows it actually implemented. So your argument doesn't hold true.

Did I say Octa will have 3 + 2 cores? Read the title "[Exynos 5 Octa] ARM bigLITTLE Overview and demonstration ".

It's a demo of how bigLITTLE works, and they clearly mention either of the two clusters can be used depending on the workload but NOT BOTH clusters. Get it ?

http://www.eprice.com.tw/mobile/talk/4551/4853305/1/rv/htc-butterfly-蝴蝶機, J Butterfly-review#ystfuv

There is only one way to deal with trolls like you -- send you back to school.

The whole community doesn't have to suffer for trolls like you. You need proof, I had already given you enough in my previous posts. But you guys are so pathetic, can't even read properly. Read the following properly before posting something even more stupid --

1] http://www.arm.com/files/downloads/big.LITTLE_Final.pdf (page 7, big.LITTLE MP Use Model)

2] Check the following slide:
[Xperia Z General] randomuseresato:
Don't keep posting the same thing again and again. Do you think I personally made that demo video and uploaded in my personal channel?

1. The above pic has not been posted by Samsung and there is no mention of Exynos Octa here.

2. The video is much newer than this documentation and also made by ARM itself where they have mentioned only one cluster can be used at a time in their implementation. The video was chosen by Samsung to demo the Exynos OCta and not your above posted picture.

3. Samsung Top executive has himself accepted that Octa is just for marketing and its actually quad core. Let me quote his exact words

" Although this is technically an octa-core CPU, many could argue that this may be a bit misleading for consumers, since these are not eight equally powerful cores. And again, Nvidia hasn't branded its Tegra 3 and 4 as "penta-core" CPUs, so it has chosen a different route by not counting the companion core. However, Samsung's Agarwal argues that "going with the notion of quad would not really differentiate it [the Exynos 5 Octa] much, because there are so many quad-core processors out on the market." He then goes on to explain that the end user doesn't understand or care about the exact type of CPU used

http://www.phonearena.com/news/Samsungs-Director-of-Marketing-System-LSI-talks-Exynos-5-Octa_id38884

So, you think you know more than Samsung itself? :)

Tell me then why didn't Samsung use this picture or upload a video that said all cores can be used at the same time.

Please at least think before posting something. You have no proof that shows Samsung Exynos OCta can use all 8 cores and now when Samsung itself has explained it, you want to show you know more than Arm and Samsung.

I think it's you who needs to go to school. Read that PDF. There are two implementations of big.LITTLE. The first one is Task Migration Use model where all cores in both clusters cannot be used. And the other is the MP Use model where both clusters can be used at the same time.

So big.LITTLE and big.LITTLE MP

Exynos OCTA uses the former and not the latter so this pic argument is completely invalidated. Samsung isn't even using the MP Use model. There is NO mention of big.LITTLE MP by Samsung anywhere. That explains why Samsung chose the video showing Task Migration use model (which they use). Also in the MP Use model all 8 cores remain active when heavy tasks are performed. For battery life savings, Cortex A15 can go into sleep while the Cortex A7 cluster is used. But Cortex A7 do not go into sleep. Whereas in the Exynos demo they clearly show switching between A15 and A7 cores depending on task, which makes it clear that the MP model is not used in Exynos OCta.

See the attached pic, it shows how switching works between A15 and A7 clusters. In big.LITTLE MP model this kind of switching cannot happen. Also it requires some major changes to the OS scheduler to support this mode (asynchronous MP).
[Xperia Z General] :
^^ Keep trolling, it suits you ^^

Your photo doesn't show anything about big-LITTLE implementation. It's not the first time this photo have been posted. It's taken from a leaked Samsung LSI slides.

Enjoy!
[Xperia Z General] ZeDestructor:
In that case I'll be calling my i5-3570K an 8-core chip (each core has a math co-processor in it). That fine with you? /sarcasm

As I've said at least 3 times before, and randomuseresato as well, big.LITTLE NEEDS NEW Drivers to enable heterogeneous MP. Drivers that are NOT available yet. This will be the case for a while as ARM together with Samsung, Qualcomm and others work on said drivers.

You have to understand, heterogeneous SMP is a new thing, and a LOT of work has to be done with regards to hotplugging and scheduling, something that the mainline Linux kernel has only recently started working on.

In comparison, massive linux clusters (supercomputers for example) use a node-based system (as I understand it) where you detach physical nodes (racks with1-4 processors in them) and work on those seperately while the rest of the nodes function independently.

This is different to stuff like IBM's zOS and mainframes where you can literally open live system, rip out a CPU, plop a new one in, close it up and put it back WITHOUT POWERING OFF THE NODE, LET ALONE THE NODE!

THIS is what big.LITTLE is, and even then only partially since mainframes have many of the same processors in the same machine connected to what amounts to a single motherboard (contrast to x86 supercomputers where individual servers are plugged together using something like InfiniBand and aggregated via a low-latency network).
[Xperia Z General] randomuseresato:
You're the one who is trolling, not me. If you are right, show us proof that Samsung Exynos Octa uses big.LITTLE MP model and not big.little task migration model. No Samsung press release mentions big.LITTLE MP, then why are you posting about MP model? :rolleyes:

Official Samsung page describing Exynos Octa.

http://www.samsung.com/global/busin...rogeneous_bigLITTLE_Processing_on_Exynos.html

What is big.LITTLE Processing?

ARM big.LITTLE processing involves a single SoC architecture that contains two types of CPUs - one "big" CPU cluster (Cortex™-A15) that specializes in high-performance tasks and one "LITTLE" CPU cluster (Cortex™-A7) that excels in power management. Depending on the intensity of the task at hand, the system can switch workloads between the two types of CPUs to achieve optimal power efficiency. When making a voice call, texting or sending an email, the system can rely on the Cortex-A7 CPU to execute the tasks while minimizing power usage. For web browsing, flash playback or intensive gaming, the powerhouse Cortex-A15 CPU

takes over

the task.

As mentioned in the same PDF you posted, in MP model you can't switch to Cortex A15 but during high workload both Cortex A15 + Cortex A7 are used. But clearly as mentioned above in Samsung's implementation workload is SHIFTED between both cores and not BOTH clusters.

Big.LITTLE Results with Exynos

Samsung has already implemented big.LITTLE processing in its family of mobile processors and this will be released soon. Big.LITTLE architecture also performs at an A15-comparable level,

meaning that there is no observable difference in performance between a big.LITTLE configuration and an A15-only build

, but the difference in power savings is substantial.
[Xperia Z General] :
Yes, if you want you can "brand" it anything you want. Octa is a brand name, it's wonderful

marketing

from Samsung. Other companies should take note. But the question here is whether all 8 cores can work simultaneously? Yes, it can. As simple as that. Whether the drivers are ready or not is a totally different matter. Does Anand/Brain know whether drivers are ready for Samsung? I doubt that, unless they work for Samsung.

Nice that you mention about hot-plug components in enterprise world. I have been working on enterprise storage for many years. Handled a lot of stuffs from Symmetrix, VMAX, CLARiiON, VNX, EVA, 3PAR to even SMB products from LeftHand etc., We deal with boxes with more than 1000 drives or upto 16 processor and 512GB Cache in a single system. I haven't worked exclusively on mainframes, but I do know about FICON/ESCON connectivity required for them to connect to storage. So, I do have fair idea how system components are replaced and how redundancy is maintained. In this world, data flows at 16Gbps :cool:

Quit Trolling already. Check the official Samsung link I posted that describes they are using Task migration model and all 8 cores are NOT used.

[Xperia Z General] ZeDestructor:
Nice. But then you (of all people) should know that Samsung has so far made no indication for having the drivers up and running, and from the video randomuseresato posted, it looks like they have no plans to make the necessary drivers themselves. Shame, because having the full core pool would be fun to try and get the best battery life out of...

As for Anand/Brian not knowing, I suspect they have their sources. AND Samsung calls the chip a 5450 (second number is the number of cores. Has been since the Humminbird days). If Samsung does get the full heterogenous SMP up and running, I'll definitely be taking my hat off to them.

[Xperia Z General] :
Well, I won't speculate what Anand/Brian knows. They could definitely have their sources, and I am not going to challenge them. My whole point of argument was that it's

possible

to make use of all 8 cores. The design guidelines are there, but whether Samsung has drivers/firmware to make it an efficient system is something we have to wait and find out. I am not much concerned, as I don't think we can gain much from using all 8 cores simultaneously. If all 4

big

cores can't handle something properly, what would additional

small

cores achieve? I am more concerned about how

fast

the cores can switch and how threads will be prioritized based on workload. We will find out in few months.

I think the number is 5410 as I recall from the presentation. There was also a tweet from Samsung about this, which was then removed.

There is a rumour about 5450 being a pure A15 SoC with Mali-T658 MP8GPU. Definitely for Tablet/Chromebook type devices.

Well i am a fan of TW as much as people say that build quality sucks i actually disagree, they used to to say iPhone better, faster. Better built.... 80% of the guys i know use it and 90% of them dropped it once and it broke, i have an i9100, bought the Note N7000..... One awesome device performance overall was great till JB Leaks, not stable but understandable for a leak.

UI nice!! Useful features, 1 sec for loading isnt the end of the world to me, it has swipe for calls and messages fast methods...nice looks indeed.

We used to say who needs more than 1GB of ram and now JB eats it on breakfast, am octo cpu ? Sure who knows what will go next year ,the dual lasted one year and now the quad too in 2014 you think we will see quads ? (my guess is at the museum) go figure what google launch this time or after.

Xperia is great love the look, specs, power, waterproof very reccomended for my kind of work.

My only bad opinion is the unreplaceable battery, for a weekend i dont like carrying the charger its my only down side....

GS4 sounds great so waiting to compare hopefully will choose between them for a device to poses 2 years min cause its expensive...

Haha, my bad. Its all 54x0 :P

And that does indeed seem like a typo for the A6X. It will indeed be interesting to see how the cluster-switching works.

As I recall, Tegra 3 basically did an immediate disable of the 5th core upon being woken up in order to get good responsesiveness... It's been a while since I sold my One X so I may be remembering things wrong though... There's a good chance Samsung does something similar and simply do a full switch to high-perf cores the moment the phone is woken up... Now... when is Intel gonna push out a quad-core hyperthreaded Atom... The IPC on those are bloody amazing..
