Zen Meeting Vega in AMD "Raven Ridge" APU Confirmed

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.

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.
No way they will release a quad core for 350 euro, the quad cores will start at around 500-600 euro and those probably will NOT have SMT, the ones with SMT will probably start at 700-800 euro.

Yeah, well, I was wondering how they'll trickle that down. CPU will be Ryzen based for sure, but for GPU part, I have no idea. I was talking it might be Polaris based, but people said it'll be Vega. So, I don't know.

It's vega, but not the "exciting super-fast" vega we were hoping for. Those preliminary and highly unreliable early tests from compubench indicate that it falls somewhere between HD620 and NVidia GT920M.
Not bad for an iGPU, but still not quite a competitor against an entry-level dGPU like current MX150.

And so far there's only like two models with it avaliable for purchase here, and they are of course ultrabooks so no quad cores. shakesfist.gif

Actually - three ATM! :laugh:
MSI PL62-7RC and Clevo N850HL are both quad-cores w/ mx150 onboard.
There's also quite a few more on the way:

:roll: yeah of course, APU prices will rise from 150 bucks to 500-600, just because Ryzen replaces FX cores and a whopping 256 extra shaders. Pro tip: read the thread and learn something for a change.

I don't think Vega was ever meant compete with Nvidia. I think it was meant to compete against Intel on APU level while sticking it to them on the CPU front as well. :)

Considering what we are seeing when you under volt Vega, this is interesting.
