Zen Meeting Vega in AMD "Raven Ridge" APU Confirmed

[btarunr]

It looks like AMD will combine its two latest intellectual properties, the "Zen" CPU micro-architecture, and the "Vega" graphics architecture into a single silicon after all, as reports citing leaked OpenCL tables confirm that the company's upcoming Ryzen "Raven Ridge" APU will feature graphics compute units (CUs) based on the "Vega" architecture. It's becoming increasingly clear, that "Raven Ridge" features a "Zen" CCX unit, and a "Vega" based graphics core with up to 12 NGCUs, making up 768 stream processors. The "Zen" CCX talks to the "Vega" graphics core using Infinity Fabric, the same interconnect used between two CCX units on the "Summit Ridge" silicon, and between two "Summit Ridge" dies on the Ryzen Threadripper MCM.

The "Raven Ridge" silicon will hence feature up to 4 CPU cores, with SMT enabling up to 8 threads, up to 8 MB of L3 cache, a "Vega" based graphics core with up to 12 NGCUs making 768 stream processors, a dual-channel DDR4 integrated memory controller, and the same integrated southbridge as "Summit Ridge," featuring two SATA 6 Gb/s ports, and USB 3.0 ports directly from the SoC. In addition, you get a PCI-Express 3.0 x16 interface for graphics, which can be split into two x8 for 2-way multi-GPU. The OpenCL listings speak about two distinct variants, one with 11 NGCUs, and another with 8. AMD plans to roll out the first "Raven Ridge" based products as Ryzen 5 series and Ryzen 7 series mobile APUs, with a desktop debut a little later.

looking good! I will be ready for some ryzen Vega APU for a itx upgrade.

 

[RejZoR]

Well, I'll have Vega after all hehe. Waiting for new Ryzen based APU's since the announcement. So I'll be able to retire my trusty AMD E-450 laptop and replace it with Ryzen+Vega APU. I just wonder how low they'll go with them. The laptop I'm aiming needs to be at a 350€ price bracket. It's probably still gonna be quad core without any HT I'm guessing.

 

[Nephilim666]

Chuck a full vega on socket tr4 with 16 cpu cores. The space is there, would need a big jump up in power delivery but it would be unappealing to miners since it can’t be parallelised.

 

[THU31]

The GPU part seems rather weak compared to the CPU part, knowing what a poor card the RX 460/560 is.

Weak compared to a 1050, but compared to an Intel HD Graphics or even Iris Graphics...

 

[Liviu Cojocaru]

I am really curious to see how power efficient this will be and what kind of temperatures will have under load

 

[IceScreamer]

Hm, IF I manage to live with this HD4650 for a while I might actually get this APU, the RX560 isn't that much slower than my (now dead) HD7870XT.

 

[Lionheart]

Awesome, now put these in cheap/decently priced laptops & barebones PC's

 

[Vya Domus]

Meh , I would much rather want AMD to go hard with their mobile CPUs than with APUs. I am tired of seeing laptops with a 7700HQ and measly 1050 for a grand. Ridiculously unbalanced machines , I would much rather get something with a mobile R5 1400 and a 1060.

 

[TheoneandonlyMrK]

Im really interested in how the memory is configured , likely it won't have Hbm so what's the plan and how will that affect performance.
In Amds prior Apus they were bandwidth starved but with infinity fabric running at decent 3200 and the same as ddr4 speeds this could be quite a useful Apu .

 

[chaosmassive]

RIP :
-RX 460/RX550
-Xbone
-PS4
-G4560
-any APU older than this

That'll always be the case till you get HBM2/3 or ES/eDRAM to stick to an IGP. That or eight channel memory ala EPYC

 

[beautyless]

I wonder it will has higher price than Ryzen 3 1200 @4 Core, 4 Thread, 8MB without GPU

 

[dyonoctis]

A six core with 24 NGCUs (1536 stream processors) with 4gb of on board HBM would have been a sff dream. if only...

 

[T1beriu]

Raven Ridge = Zen + Vega was confirmed like 6 months ago by AMD.

Zen Meeting Vega in AMD "Raven Ridge" APU Confirmed

It was confirmed a long time ago. It's already kind of late for release, actually.
I've already sold my Dell Vostro and saved enough money for an upcoming Thinkpad E475(A475?), but I'm not sure how much longer do I have to wait.
Lenovo barely announced zen mobile refresh for Thinkpads 2-3 weeks ago...
Damn you, AMD! Hurry up, Lenovo! I want my portable workstation w/ Ryzen 5 2500U and Vega graphics!

Rysen mobile and new ASUS ROG laptop was already shown at computex (w/ RX580 onboard). One helluva gaming device.

I know , but I want to see lower end Ryzen parts for laptops at 1000$ or under.

 

[TheinsanegamerN]

And they will all be TDP-downed versions with forced single channel memory, 768p screens. and 5400rpm hard drives, because OEMs dont care and AMD cant be assed to perform quality control of their products ala intel and the ultrabook.

But hey, super excited if AMD finally pulls its head out of the sand and works directly with an OEM to ensure a proper quality notebook..

When did Lenovo confirm zen refreshes? I cant find any articles on it.

Extremely unlikely. Intel doesnt even make a CPU only mobile part. All mobile CPUs except for that fancy pants asus ryzen rig are using APUs, because they are far more energy and space efficient then CPU+GPU.

You might get a raven ridge+1060, but dont count on a 1400. Especially dont count on seeing that under 1k. dedicated CPUs are a tiny niche.

Not exactly sure what you are saying .There is no special silicon for mobile per say , they are just underclocked/undervolted desktop CPUs with perhaps less cache. That is what Intel is doing , and there is no reason why AMD couldn't. They just need to work close to OEM.

Ryzen is very power efficient.

 

[silentbogo]

There was also an unknown ultrabook prototype (who's AotS score probably leaked not too long ago). But it's far from "gaming", just an ultrabook.
You may get something decent in $1000 range by winter, but don't hold your breath on mobile Vega dGPU.

Not the case with Ryzen Mobile. Judging by TDP, AMD was cherry-picking dies with all working cores for mobile chips (one CCX, not 2 like in desktop Ryzen). All the leftovers went into desktop chips.
A mobile R5 2500U according to the leak is a 35W CPU with 4c/8t!
BTW, I've just stumbled upon Compubench results for Ryzen 5/7 Mobile:
https://gfxbench.com/device.jsp?D=AMD+Ryzen+5+2500U+with+Radeon+Vega+Graphics&testgroup=overall
https://gfxbench.com/device.jsp?D=AMD+Ryzen+7+2700U+with+Radeon+Vega+Graphics&testgroup=overall

Not complete, not confirmed, but very promising.

What I meant to say is that there is no different/dedicated silicon that they need to manufacture , just re purpose already existing dies by underclocking/configuring them.

R5 2500U at 35W sounds insanely good. My hopes are that such CPUs from AMD might drive down the prices of laptops and allow OEMs to place more powerful GPUs for the same money.

Not lenovo directly, but via A275 and A475 certification applications:
https://sertifikasi.postel.go.id/aplikasi/index?key=models&value=Thinkpad&pagegrid=2
Lenovo already has Bristol Ridge APUs in their E-series low-budget models, so there is absolutely zero reason to make the same laptop with the same internals under a different name.

Some more thoughts and educated speculation here:

I'm going to guess, given the other limitations of an iGPU, the graphics performance is going to be somewhere between a RX 550 and RX 560. Not bad for a iGPU for sure.

 

[linuxgamer72]

Would be great if AMD was using it's Vega specific HBCC feature and install a single HBM2 memory die within the APU, acting as a fast last level cache for the iGPU, while latter still can access the shared and much slower DDR4 memory as extended storage when necessary. This would totally eliminate the downside of high latency and low memory bandwidth issues typical for CPU-integrated graphics in most use cases. 3+ TFLOPS iGPU without hard memory limit on a Zen-based 8-threads APU? Wishful thinking...
