We'll find out soon enough I guess.

Speaking of Threadripper, Linus dropped some pretty heavy hints that Threadripper is two Ryzen 7 cores on a single package. I always knew that the architecture would be modular but having what appears to be two identical sockets merged into one was eye opening. Hopefully performance won't suffer too much if it's an SMP-like architecture.

Wouldn't this be sort of related to the Navi technology they are working on on the GPU side?

I'm not sure how I feel about this... I was hoping they'd be binned Zeppelin dies, since Ryzen 7 yields seem to be topped out.

....unless Zeppelin are actually four Ryzen 7 dies with some extra sauce, then I have no loving idea how to assess parts anymore.

Yup, AMD is all-in on Infinity Fabric. Their plan for Navi to do the same thing on the GPU side that they're doing on the CPU side right now. If they can manage to glue together several under-volted Polaris/Vega cores and have them function as a single unified GPU I think they'll be very successful.

I'm interested to see what the die layout looks like for the 16 core Threadripper part. They showed off the 32 core layout and it's 4 8-core modules arranged in a square. I'm wondering if the 16 core will be; 2 modules on one side of the chip? diagonal? centered? Or (worst case) will it be some sort of conglomeration of various combinations of modules with some of their cores disabled.

I really can't imagine them doing that last one; but it's AMD.

That's probably exactly how they're going to do it - gives them a way to recoup as many defective dies as possible. They did it for their 4 & 6 core products, probably just scaling the same thing up.

If they can get the infinity fabric fast enough and low enough latency, then it shouldn't be too much of an issue, as long as they address the NUMA issues and make sure that all the context switching costs are known/available to the OS. It would be a great way to salvage marginally performing chips, or chips that are super great except for that huge defect in core 3.

Since its single cpu NUMA doesn't come into play with infinity fabric, do note that 1700-1800x parts don't do numa and had other fixes come in without having to use NUMA as a scheduler.

There are probably more optimal arrangements, it's kind of an interesting question.

Are there any model systems (toy or real-world) where both the logical design (eg VHDL) and the design constraints on the fab process are known, ideally along with a datasheet on the process with something like "thermal output per mm^2" according to some clock/duty cycle rating?

(I doubt it but someone please surprise me)

Worse comes to worst you should be able to discern a lot of this experimentally - delid that bitch, toss some thermal-sensitive laquer on there, and record it as it goes through a test suite designed to gently caress with each particular stage or execution unit. I'm 100% sure one of the reviewers did this for Ryzen?

Aye. They are currently parading a bunch of OEMs with increasingly thick accents, I'm not sure I've understood much of the past 10 minutes.

Edit: Apparently the ROG Ryzen 7 based laptop is 60% faster than any other laptop. Needs qualification I think.

That's supposed to be 704 Vega cores as well, so why even the gently caress is Big Vega approaching 550mm˛? That kind of performance should be pretty incredible for gaminmg even, like 1080p medium-high on even the most recent titles, if the performance of the A12-9800 is anything to go by.

No pricing though, but I don't think it's going to be like Intel's i9s and having 64s lanes on even the cheapest Threadripper CPU could make for a strongly compelling option despite Ryzen trailing in performance overall.

I feel like AMD is killing it right now except for the impending desktop Vega disaster.
Based on the Ryzen TDP scaling we've seen so far they're in a really good position for mobile. Doubly so if they can pair the APU with a few gigabytes of HBM.

Geez if they can just put a "lousy" 1GB of HBM1 on their APU's it'd be a huge win for iGPU performance. It could probably compete fairly well with some of the mid-ish range dGPU's at 1080p or less resolution with that. Seems like that isn't gonna happen though. At least not for 2017.

So without availability date, I suppose there won't be early samples going to reviewers any time soon?

As much as I'd like to see a zen quad with a RX480-level GPU on die paired to a stack of HBM, but it doesn't make any sense for Raven Ridge when and the memory controller can push 30-40 GB/s on DDR4 at average clocks. The GPU part is absolutely tiny.

Yeah it will, look up Intel's Cluster-On-Die architecture. You can have multiple numa nodes defined on a single socket. You need something to indicate to the OS where the crossbar/whatever is and to schedule threads around it unless you want even more erratic performance.

Yeah they'd have to pump up the iGPU to make full use of it but it'd still benefit the iGPU they're going to put in Raven Ridge too. I suspect the iGPU in Raven Ridge will reeaaallly love higher clocked DDR4 just like the Bulldozer based iGPU's saw nice performance boosts with higher clocked DDR3.

The Raven Ridge platform is my most hype Vega product. Hopefully there are bigger ones than the demo unit at the show for mobile platforms. I'd take upscaled 900p@60 or with Freesync 2 in a thin and light, or 1080p Freesync 2 in an XPS 15 style computer.

The Threadripper platform is looking super neat, too. Since overclocking won't get it to Skylake-E performance, I wonder if all those PCIE lanes and soldered IHS are going to pull folks to AMD.
