AMD 3nm Zen5 APUs codenamed “Strix Point” rumored to feature big.LITTLE cores

I really have never seen the point of this in desktop computing. Why would I give up a few of my "big" cores that are already quite efficient at idle for little cores that have no grunt to them.

3 nm, that's the future right there.

They don't have any little cores though.

They're named after an Asus line?

Just bring back the operon a1000 in a working version.

Why the hell would it have 8+4 cores when it has up to 16 cores now. Not to mention if it's really targeted for 3nm. Makes no sense.

Gonna go with fake rumor.

The current highest core APU is only 8 cores.

11 : Anonymous2021/04/27 17:06 ID: gw2ker5

The CCD currently have 8 cores, some CPU's just use 2 or more of them.

When you think about it, big.LITTLE is kind of crude. There is a whole range of specialized silicon you might or might not put in a core to make it bigger or littler. Deciding what to leave out of little and what to put in big is a balancing act with tradeoffs.

Instead of forcing yourself to choose between big or little, it would be better if you could configure your cores on the fly with fpga's, and put in only the functionality you need. I bet that's what AMD is going to do, rather than copy big.LITTLE, several years after Intel does.

3nm isn't next to quantum tunneling for electrons?

15 : Anonymous2021/04/27 17:13 ID: gw2lis0

Given that transistors aren't near 3nm by any metric, no.

16 : Anonymous2021/04/28 00:49 ID: gw4a7wm

3 nm does not refer to actual size. Anything below 22 nm doesn't

17 : Anonymous2021/04/28 01:39 ID: gw4g9hl

Everyone in this thread is right in some way - 3nm as a measurement is in the range for quantum tunnelling but as has been mentioned, "nanometres" as used as a descriptor for the fabrication process aren't analogous to nanometres in terms of measurements anymore. Bit of misleading marketing really.

Doesn't quantum tunneling become an issue at that small scale?

And Zen3 derivative is the LITTLE cores.

Serious; its often forgotten how small zen3 chiplet is. 84mm2 or so and only a meager 10mm2 more than zen2. Its lean stuff and engineering miracle.

I think big.LITTLE can work decently as long as the little cores really are little, purely for light and background tasks so the big cores don't need to spin up. If the little cores are only say half as performant as the big cores for example then IMO they shouldn't bother, better to make all cores equal and not have to deal with the headache of a non-uniform architecture.

Won’t Zen 5 be on a “more mature” 5 nm node like Zen 3 was for Zen 2? (Both used a 7 nm node technically though Zen 3’s is more dense iirc).

I would think Zen 4 would be 5 nm then Zen 5 would “probably” use a refined version of that process node, no?

Seems unlikely to jump from 5 nm node when it’s basically the bleeding edge right now to 3 nm just one gen later — unless that gen is like 2 years out perhaps. Maybe they’ll do an XT style refresh of Zen 4, who knows.

Uh I'll believe it when I see it considering sometime last year an AMD engineer ruled out even putting resources towards BIG.little

I wonder how are they gonna name the nodes when they reach below 1nm

34 : Anonymous2021/04/28 18:02 ID: gw76i0w

I don't think this is true, I just don't see AMD doing a big. Little. Wouldn't it be more efficient to just figure out better power management to gate off components/cores.

35 : Anonymous2021/04/28 18:21 ID: gw79a5z

It says Phoenix(7000series) is due in 2022? But what about the 6000 series APU Rembrandt? Wouldn’t that make sense to come out first since 5000 Cezenne will be out this year 2021

So it'll be Arm? big.LITTLE is literally the name for the architecture from ARM. What's the name for this in the AMD64 space?

37 : Anonymous2021/04/27 16:09 ID: gw2caj5

Why don't the AMD marketing people just give their chips a bigger number than the intel chip and get it over. Instead of Ryzen 6000 they can just call it the Ryzen 12000 - in a massive marketing win over the intel 11000 series.

Ryzen 3 just got released. Jesus christ guys why can't you give it a rest with rumors and looking for products while current one has barely even been released.
Go talk about ryzen 3 and sky lake and some crap. I just get depressed every time product gets released it's like as soon as it is released "OH THE NEXT ONE DESTROYS EVERYTHING IN THE UNIVERSE WITH 80% MORE GAINZ BRO!" like srsly. Where's the enjoyment of the released products?

I remember when 3xxx RTX was released and rumor mill was already spewing out 4xxx and people just talked how much it will bring on the table as well as with RDNA 2. Like give it a rest.

40 : Anonymous2021/04/27 19:40 ID: gw36kd8

Pretty sure Ryzen 3 released in 2017, but Zen 3 did infact release half a year ago.

On a serious side, rumors will always be there, it’s the way it is. Technology is constantly advancing.

41 : Anonymous2021/04/27 19:42 ID: gw36w1t

I meant zen3 yea. Im aware its constantly advancing but the problem is we nevee enjoy the present anymore. We just talk about what will happen in the future and almost never anymore how awesome released products are. Makes it all worthless imo.

Yea, good luck with that implementation. It took how many years for OS and games to learn to use more than 1 core.

43 : Anonymous2021/04/27 19:45 ID: gw37bjj

big little has been a thing in phones for a good few years, so there's no reason why it wouldn't work in higher power scenarios. Even more so that from program standpoint this isn't that much different from SMT core.

What is more, the program doesn't even need to be aware of big little. The only thing that does is the system scheduler.

44 : Anonymous2021/04/27 20:06 ID: gw3aa61

I didn't say it wouldn't work. I said it would take awhile for OS to implement it.
Windows 10 didn't optimize their scheduler for Ryzen until 1903 came out so you are freaking delusional if you think this will work well out of the gate.

and about AMD's 1nm Zen6 APU codenamed "little big shit"...

46 : Anonymous2021/04/27 17:55 ID: gw2rl59

No. Nobody making components for PCs would be this stupid as to use a widely known trademarked term directed to computing such as ”STRIX” for an internal project name. The IP lawyer would shut it down immediately.

Hell, most would shut down the use of marks for projects that aren’t in the same market!

47 : Anonymous2021/04/27 18:02 ID: gw2sk8a

It’s a code name / internal name. You’ve clearly never worked at a big corp because having an internal name and external name is very common.

I acknowledged it's an internal name. Please refer again to my comment. As for the dig, well...I think I'm the perfect amount of informed!

I've stopped clients from using trademarked internal names for codenames both when I practiced at a law firm and also now working as a lawyer for a corporation. Particularly when my clients approached me to use a trademark from (what I still think was) a overly litigious broadcasting entity for their internal name. Internal codenames that are valid marks, in the same market, are troublesome from a number of perspectives. Especially the human ones. I've seen business people get weirdly attached to them or let them cloud their own thoughts as to what the eventual marks should be. This, in turn, can open up liability and pulling a product from market just to avoid a later lawsuit.

Ultimately I think we all can agree that external names should go through the normal due diligence before use. Internal names are no different though, admittedly, the balancing is different as the risk of liability is greatly reduced. But it is never zero.

Stop calling it big.LITTLE, that term is specific to ARM. This would be like calling raytracing "RTX", or resizeable BAR "SAM".

50 : Anonymous2021/04/27 17:51 ID: gw2qzn0

the real question: little cores like ''MODULES'' in FX-fail Series or rightful truly cores?

PLZ AMD don't go full retard again, it's Intel turn now with worse 11th gen than 10th.
