It is a move that was needed last year, when people were still excited about external GPU over Thunderbolt. Now, who knows when that will be a standard industry thing.

Seamicro's technology, which they branded "Freedom Fabric", has nothing to do with Infinity Fabric. The former was essentially a rack-level interconnect that allowed users to virtualize ethernet and storage at the edge of a torus network of individual systems (see e.g. slide 8 and 14).

Was going to argue, but you are in fact correct. Straight from the horse's mouth:

quote:

UPDATE 5/22/17 11:15 PM CT: AMD has asked us to clarify that Infinity Fabric is actually not related to any of the IP or work that AMD inherited through its ill-fated and SeaMicro acquisition.

However, I would still stand by the statement that it's HyperTransport 4.0.

In unrelated news. Here is a picture of two Asrock X399 boards. Looks like the official name for the Threadripper socket will be TR4.

The promised fix (AGESA 1006) doesn't help with NPT performance, it only fixes groupings to enable GPU passthrough.

Won't acknowledge, or haven't had the time to address, with Computex and Threadripper taking a higher priority?

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.

https://www.youtube.com/watch?v=nynBEGCtg90

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.

Pricing out the two small boxes instead of the doubleheaded monster; the old Phenom II that the two munchkins were using croaked somewhat inconveniently the other night, and I figured it's best to just move on wholesale.

They came kind of late to the game.

Who is really upgrading their pcs in this day and age? Outside of commercial market and hardest of the hardcore gamers.

PC part sales are way down compared to 5 -6 years ago and we're reaching the limit on how much faster cpus actually are advantageous to most end users.

A I5 from 3-4 years ago is still pretty loving fast.

There are two segments that AMD *needs* to make inroads in on: Server and mobile. That's where all the money is, and where turnover is most likely to happen. The former, because of all the usual buzzwords of "density" "power-efficiency" and "compute", and the latter, because notebooks are fundamentally obsolete from the moment they hit the market: Performance is strictly downhill from there, barring a miracle with MXM GPUs or adding in extra RAM. Maybe swapping spinning rust for flash, but even that is progressively less likely these days.

Everything else can be broadly classified as mindshare, from the crappiest $300 Dell box to the HEDT. Yes, we're excited about Threadripper, because that's _us_ but the real important parts here are EPYC and Ryzen Mobile.

It *appears* that Samsung, working with GloFo and IBM, may beat Intel to market with EUV.
IBM is touting 40% perf increase or 75% reduced power consumption from the new GAAFET transistor design vs commercial 10nm FinFET.

This is more bad news for Intel, I think. I can't remember if they had arrived at their next step after FinFET yet. Last I heard, they were going to switch to InGaAs at 7nm and ride FinFET all the way down to 5nm, or something like that.

edit: Now the question remains: Can AMD GPU-side survive long enough to get whatever comes after Navi onto this new 5nm process? XD

If there is a criticism that I have continually levelled at AMD, it is that they appear to be hell-bent on leaving as much money on the table as possible.

That a 16-core Threadripper part of quite reasonable clock, might retail for _only_ $849?

This implies that Threadripper, rather than commanding an HEDT price premium, as Intel has normalized over the past decade, will be a step up from R7 merely in the same way that one steps up from R5 -> R7.

And I think that this is undercutting Intel WAY TOO HARD, and that AMD would benefit more in the short-term while not harming their long-term by pricing closer to Intel, but moving down whenever Intel moves.

Either that, or AMD is burning cash to achieve lock-in on people who are increasingly turning against X299/Kaby Lake-X.

This is entirely a wild-rear end guess based solely on my observations in both the CPU threads on SA, some threads on a few other boards, and conversations I've had about the CPU R&D process with some other folks in the industry, but I suspect the following will happen:

Zen 1.0 (current Zen) will continue to receive stability and performance improvements through microcode built into AGESA. Zen 1.5 (some folks are calling it Zen+) will happen early next year; it will likely be a process refinement of the Zen architecture with all the microcode-based improvements intact, and then some. It'll be when AMD is comfortable with the process they're working with and designing for.

I suspect a die shrink would be in the cards at some point if AMD can end friendship with GloFo, now Samsung is my best friend. There's no way they could do a competitive 10nm part on the GloFo process.

Cannonlake (Intel's Kaby Lake die shrink) has been pushed back a bit last I checked.

Maybe AMD won't be cutting ties just yet. But at least it may be because GloFo has a product worth offering, rather than being a goddamn albatross:

Intel said nothing, and Lisa Su said that they were not in the business of "enabling a competitor to compete with our products".

But Apple being its own, internal, walled-off garden in almost all ways that it is... I can see why an exception might be made there. It would be a product that would be sold nowhere else.
