AMD Raven Ridge 'Zen APU' Thread

[NostaSeronx]

22FDX for Lumpy Ridge(Alter Raven Ridge with Family 15h Models 90h-9Fh) has been accelerated; http://www.globalfoundries.com/services/fdxcelerator
From the FAQ;

FDXcelerator lowers the barriers of migration from bulk nodes such as 40nm or 28nm to FD-SOI through leveraging existing design flows, design automation tools and design service partners.

Currently the ecosystem is set up around GLOBALFOUNDRIES’ 22FDX technology, with foundation and complex IPs built to suit the SoC as fab ready. FDXcelerator will extend to also include 12FDX™ as this next generation solution development gains momentum.

^-- 15h replacement to these. (15 + 16 ÷ 2 => 15.5)

With the design aesthetic of Jaguar on Bulldozer. An ULP APU for 22FDX should and could provide eight-cores and sixteen CUs within 4.5W(GeAPM(Global Efficent))-7W(STAPM(Skin Temp)) TDP.

CPU side;
All eight core stock // 1.25 GHz @ 0.5 volts
All eight core boost // 2 GHz @ 0.55 volts
Quad-core boost w/ Quad-core @ stock/gated // 2.5 GHz @ 0.75 volts
Dual-core boost w/ Hexa-core @ stock/gated // 3.0 GHz @ 0.8 volts

GPU side;
Sixteen CU // 0.4 GHz @ 0.5 volts
with Boost // 0.6 GHz @ 0.55 volts

Then fling on dual-channel 1.05V DDR4L with support of dual-4266 MHz op. Boom viable low-power console-tablet replacement. (Or... There can be 2.5D 2x HBM2 4 GB @ 1.05v(LV Mode)/1 GHz(Low Power/Low Cost stack) thus 256 GB/s)

Let's not forget the 6 inch 4K/UHD AMOLEDs... (and slim thermoelectric battery/heatsinks // double sided body temperature & device temperature)

One foundry for FinFETs: Fab 8(14nm/7nm)
Three foundries for FDSOI: Fab 1, Fab 8, Fab 10 (All three 22nm/12nm)
^-- Pretty much anyone with a WSA @ GlobalFoundries that went FinFET is #feelsbadman right now.

If anyone here here still believes Raven Ridge will get HBM:

SE: Any plans to add that kind of architecture into the CPU side?

Papermaster: We see HBM having expanded applications in the future. The biggest driver of that is the HBM cost coming down. It works great today on the high end of our discrete graphics line, and as the cost comes down, you’ll see the applications periphery grow.

SE: Is the cost the memory, the interposer or where are you seeing the problem?

Papermaster: Both. Costs come down generation by generation over any technology as it matures. As the volumes go up, HBM costs will go down. The same holds for interposer. As the manufacturing volumes go up and the OSAT industry gains more expertise in the packaging techniques, costs will go down there, as well.

Lisa has hinted HBM2 APUs for server in one of her recent calls.

I think we'll see them sooner than later.. but these will be $500+ SKUs. If they can do it on the high end GPUs I don't see why they can't do it on an APU. Cost isn't a limiting factor for a $500+ SKU.

That roadmap also shows server APUs. Also that "Disruptive memory bandwidth" bullet point hints it as well for pure CPUs.

HBM2 has clear advantages over competing technologies.. density and power savings. Both high density blade servers and ultrathin premium laptops would benefit greatly from HBM2.

In light of the new lower cost HBM and since Raven Ridge is a H2 2017 product, i will say a 8GB HBM APU for Laptops is very possibly and viable solution.

For High-End, High Performance, Thin Chassis Segment ($800-1200+)

Raven Ridge with 8GB HBM

1. Single slot solution.
2. Simpler Motherboard design and lower BOM
3. No extra DDR-3/4 dimm slots or integrated Chips
4. Single cooler design, smaller, lighter, cheaper.
5. Higher or same Graphics performance vs dGPU (RX 460m GDDR-5) of the same class with lower power consumption.

1+2+3+4+5 =
Even if the HBM APU alone will be more expensive than a DDR-4 APU, the HBM APU will make the final product (Laptop) be cheaper, lighter, with same or faster performance, consume less power, increase Battery life, be thinner.

Intel doesnt have a product like that, it will make AMDs HBM APU look like heaven to OEM/ODMs.

thoughts ??

Another option (for laptop) would be 2 x 8GB low cost HBM @ 1000 Mbps for 128 GB/s. I am assuming the DRAM used for the low cost HBM can clock that low as Sk Hynix does list 1 Gbps for its own HBM2.

With that mentioned, I do think it is unfortunate Samsung mentioned removing the ECC.

That roadmap also shows server APUs. Also that "Disruptive memory bandwidth" bullet point hints it as well for pure CPUs.

I'd say the "disruptive memory bandwidth" refers to the fact that Naples has octa-channel memory configuration. 170.6GB/s with 1P and 341.2GB/s with 2P, per node.

Yea that should put it to rest. Even if we are to see the HBM based consumer APUs it won't be anywhere soon,not 2017 at the very least.

 

[sirmo]

Looks like I am not the only one who thinks HBM2 APUs are coming:

 

[kraatus77]

I'm really looking forward to that HBM APU. gonna be a perfect light work/gaming pc.

 

[jpiniero]

I'm really looking forward to that HBM APU. gonna be a perfect light work/gaming pc.

Uh, Snowy Owl is a server chip. Not exactly a "light work/gaming pc".

 

[kraatus77]

Not talking about that specific apu, but the desktop one. i'm pretty sure they will release something for desktop. 4c/8t+ 16cu/8-16gb HBM2 for around 300-400$ maybe ?

 

[Arachnotronic]

I'm really looking forward to that HBM APU. gonna be a perfect light work/gaming pc.

Not gonna happen anytime soon for consumer use.

 

[kraatus77]

I know, i'm not in market for new setup for at least 2-3 years anyway. so enough time for amd to do something about it.

You're probably going to have to wait longer than that.

 

[kraatus77]

"Probably" , i don't think so, we'll see. it's not like that's the only thing i will buy. there will be many other cpus/gpus to choose from. so even if they don't launch it i'll just get something else.

So we will have HBM only in the top tier, just like Iris Pro. Expected to not to say the least.

 

[frozentundra123456]

Well, they show nothing with HBM on that roadmap through 2019 except the 16 core server APU.

 

[deasd]

Rumor again, still about HBM(2):

[Exist50]

Hmm, bitsandchips have gotten some things right before, so clearly they aren't operating completely in the dark, but their track record is a bit spotty.

 

[AbRASiON]

According to Fudzilla:

- 4 Zen Cores, 512KB L2 each, 8MB L3 shared
- Up to 11 GCN 4th Generation Cores (704 SPs)
- DDR4-3200, ECC (some models)
- H.265 10-bit encode and decode, VP9 decode
- Up to 4 DisplayPort 1.3s, an HDMI 2.0 or DisplayPort 1.4
- Next generation chipset with USB 3.1, including USB Type-C, NVMe
- 45-65W TDP (socket AM4 version)
- 2017

Just occurred to me, how unfornutate timing this is. I hope it's revised.
We're right in the middle of the internet losing it's mind over 4k - but to do 60hz, 4k, HDR and 4:4:4 - you need HDMI 2.1 or higher (which doesn't exist yet)
I'd like to think 2.1 gets added for those that use this CPU / APU for their HTPC.

 

[Spartak]

Hard to weed through this thread for data but two questions:

- 45-65W TDP range for the desktop parts is kind of disappointing. I was hoping for 35W as I'd love to build a fully silent / passive cooled SFF with this part. Any news about the desktop APU TDP range since the OP?
- any updates / rumours concerning launch date? still 17H2 or is it even 18H1?

edit: ooh I see from the above link that it's going to start from 35W. Hopefully clocks will be decent around this TDP. Fingers crossed for base 3GHz...

 

[krumme]

You can always hope for something 25% faster than a iris pro solution at 10w lower tdp and perhaps at half price.
Sure its getting to be the most interesting product in the portfolio for many enthusiast and zen looks like a good fit for that purpose unlike high perf desktop but i would settle for some hopes a good deal more realistic you cant have it all.

 

[frozentundra123456]

Hmm, bitsandchips have gotten some things right before, so clearly they aren't operating completely in the dark, but their track record is a bit spotty.

Even that article says they dont know if both will be commercialized. It might be nice for mobile, depending on cost. For desktop, even 16 CU is RX460 performance, assuming no bandwidth or TDP limitations, so I dont see a place for it except for SFF builds where there is not space for a conventional card. I mean 460 is low end now, in two years, which is the earliest I think we could see an HBM APU, it will be even more marginal for a desktop.

 

[krumme]

In family we also use our ultrabooks for occasional gaming. Not going the big notebook way. And man it would be nice if those ib to skl ultrabooks had faster and better gpu. They are just damn slow for gaming and I think it have stagnated a bit here the last years. Hopefully compettition will bring some faster progress back.

But 4K is old hat. AMD's graphics guru said we need 16K for true VR immersion and I read an article recently with a bunch of JPGs on my 1440 monitor that was ostensibly showing me the need for 8K (because they look so "painted-on").

Is that a reply to me? I didnt say anything about better graphics performance or price. 4K capable is enough for me, but yeah I don't think I'd want to pay more than 200 for such a chip.

Intel released a base quad 35W TDP APU in oktober '15 (the 6700T), is it that unrealistic to expect AMD to hit that mark two years later? Well maybe it is. They'll probably hit it around 45W though. Might take them a year or two extra to bring that level of performance to 35W.
