A few people are in there reporting it happening at stock, maybe it's a specific mobo bios.

I wonder if there are some chips that really lost the silicon lottery and just don't have enough volts at stock clocks to keep up under a really intense long-running 100% load situation.

Some people in the Gentoo thread reported that higher load line calibration settings (= higher Vcore under load) fixed the compiler bug so you might be right

Would zen2 with just a slight bump to volts all around be a lazy fix for such things or is zen 2 going to be on 7nm?

Also what happened to intels 10nm process?

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:

SwissArmyDruid posted:

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.

https://arstechnica.com/gadgets/2017/06/ibm-5nm-chip/

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

AMD is planning on skipping 10nm and using ibm/samsung/gloflo 7nm in 2018 for zen2, and zen3 will use 7nm refined.

For the last month, I've been a happy mother of a 1600X based system. Here is what I got:


Fractal Define C
Ryzen 1600X (Corsair H110i Extreme)
Asrock X370 Taichi
G.SKILL Flare X 16GB 3200Mhz
XFX RX480 8GB GTR
Samsung 960 EVO 1Tb
Seasonic Prime 650W

Very satisfied so far. Was originally going for the 8 core, but 1600X had such a good price that I decided to go for it. With the money difference I chose to double the PCI-E SSD size and refrain from getting a HDD altogether.

Someone handed me some industrial PWM Noctua fans too (the black ones), so I promptly put 5 on them in the rig (2x140 on the rad, 2x140 on the top and a 120 on the back). Was seriously doubting whether that was a good choice as soon as I posted, those 2000rpm fans are pretty loud!. I was psychologically ready to dabble on speedfan for a day or two, but I found out that simply running the Asrock BIOS option for auto fan control made the whole rig whisper quiet. The fact that both GPU and PSU run fanless on idle/browsing/movies etc helps a lot too.

Have not tried OCing yet, other than setting the memory to its 3200Mhz 14/14/14 profile. The whole thing is reporting pretty good temperatures though, to the point that I don't hear the fans unless I'm stressing the system.

And running something like Furmark/Prime95 for an hour or so provides still glorious temps (that 280 AIO cooler is worth it)..albeit with very increased sound.

So far, so good.

"Intel(R) HD Graphics Gen9; 694C:C0 (1720SP 47C 1GHz, 528kB L2, 10.4GB 800MHz)"

That can't be right, 1720 SPs doesn't divide evenly into the 64SP CU/NCUs that GCN is built from.

Yeah but it'd blow their power efficiency even worse than it already is. They are already practically tied with Intel's chips rather than being 30-50% ahead like their TDP numbers imply.

likely a type error, 1728 SPs would mean 27 CUs, which must mean it's a MCM design with an intel chip and a rtg gpu

or it could be the GPU on-die along with the intel CPU, in which case on how that will work

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.

Maybe it's a fusion of Intel and AMD design, possibly Intel layout and command processor but AMD shaders and geometry processor? Intel works in threes, so a slight typography error could mean this is a scaled up and enhanced Iris 580 with GDDR5 memory and 384 bit bus, so 1728:216:27, but I can't for the life of me figure out that weirdass 10.4GB memory config. Everything else is divisible by three though.

That's really only feasible with HBM1 though.

So for maximum WTF, it's the shell of a Intel iGPU scaled up to a desktop part, MCM'ed to a CPU, with most of it's guts replaced with AMD tech, uses AMD's HBCC tech, on an interposer to support 6 3-hi stacks of HBM1 and using half of the systems 16GB of DDR4 memory as shared memory (and thus reporting 10.4GB) for also having a stupid large 6144 bit bus. I cannot discern this theoretical parts purpose.
