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.

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 .
-RX 460/RX550
-Xbone
-PS4
-G4560
-any APU older than this
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.
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.
Ryzen is very power efficient.
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:
gfxbench.com/device.jsp?D=AMD+Ryzen+5+2500U+with+Radeon+Vega+Graphics&testgroup=overall
gfxbench.com/device.jsp?D=AMD+Ryzen+7+2700U+with+Radeon+Vega+Graphics&testgroup=overall
Not complete, not confirmed, but very promising.
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.

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.
