If they do 16 CPU's + a moderately powerful GPU + 32MB L3 on one die I'd be surprised. It'd have to be gigantic even on 14nm. Definitely a server part. Totally unfounded speculating here: Maybe they'll go multi die CPU and GPU and use the interposer to link up the CPU, GPU, and HBM memory dies? They'll already have to put a interposer on there for the HBM to work, why not leverage that interposer as much as possible? Any reason why that couldn't work?

if HBM is fairly small comparatively, could you get away with a video card that aren't so big? Something that just slots in next to the CPU and is around the same size. You might not need to create a APUs. Just create a version equivalent of a HD5000 on the CPU and create bundles that include more powerful GPUs I'd love a PC where the only requirement of the size of the case is the size of the cooling. But it still might be stupid confusing compared to APUs.

Power circuitry + heat from the VRM's and GPU would necessitate that you have it a decent distance from the CPU and a decent sized HSF for anything with mid to high range performance. For low end stuff it might be doable but low end GPU's wouldn't have HBM anyways.

What's the use case of a fast-ish iGPU in a server though? You either don't need a GPU at all, or you're doing heavy GPGPU work and will be stuffing every PCI-E slot with discrete cards that crush any iGPU.

For example if you have two threads of high priority busy-waiting for work to be finished by threads of lower priority the system can stop making forward progress as the operating system will not pre-empt the higher priority threads. On a four core system this situation wouldn't happen. I don't remember ever running into a game that had set itself to High or even AboveNormal priority. I'm pretty sure they all run as Normal priority.

I bought a AMD FX-series CPU (specifically an FX-8370)  I also bought a Noctua NH-U12S CPU cooler because my computer was making too much noise. But while testing the noise level at full blast and 100% CPU load on all 8 cores, I noticed that my CPU is throttling (those dips in the temperature graph are from the cores dropping down to 1500 MHz):  Speccy and Asus fan Xpert don't agree on what the cpu temperature actually is, but neither 42C and 55C sound so hot that it should be throttling. Especially since with the stock cooler I'm pretty sure the temperature rose to over 60C at points. So what should I try? The only thing I can think of immediately is reapplying the heat sink and the thermal grease.

I believe this has happened to a handful of AMD boards, and even some Intel ones (such as the notorious Gigabyte that was massively cut-down from the original model). The VRMs are probably cooking. I barely even want to ask why you bought this CPU. HalloKitty fucked around with this message at 14:52 on Apr 15, 2015 |

I bought it because it was compatible with my mobo  (or so I thought at least)I've been using it for a couple of months now and have not noticed anything except now that I specifically watched the temperatures under full load. Oh well, I may have owned myself one last by deciding to go AMD almost a decade ago.

What motherboard? If it's one of those lovely 4-phase vrm boards with no heatsinks on them it's possible it's not able to handle the chip. Also apparently per-core temperatures on that aren't supposed to go above ~61-62c so maybe there's something in the board's settings (cool and quiet???) forcing it to throttle down.

I remember the computer I built in the summer of 2006. It had an Athlon 64 4000+ in it. I was just a naive teenager at the time playing with his parents money, and didn't even think to research to see if a better processor was coming out within the next month or so. Well, wouldn't you know it, but the C2D hit almost exactly a month later. That was a tough lesson to swallow

Yeah, I used AMD back then because I liked AMD in the Athlon64 period, after that I've just upgraded one component at a time because something has always been backwards compatible. I bought that processor because it was the most powerful one that is(?) compatible with my mobo, electrical power wise. Except lol, owned. I have to check the temperatures of the components on the mobo...

The Athlons/Phenoms were still reasonable choices when the Core chips were out. It wasn't until Intel's Sandy Bridge displayed a massive leap forward in efficiency while AMD's Bulldozer just kinda fell on its face that the gap became so huge that it's really hard to recommend an AMD based build. It's pretty much the reverse of the Pentium 4/Athlon XP era.

The original Phenom was balls. The Phenom II was fairly reasonable - picking up an X3 and unlocking it represented killer value; and the Phenom II X6 was better than the FX series that replaced it for some time (embarrassingly for AMD).

Yeah, there was definitely a performance gap in that era but it wasn't so bad that it was insane. AMD systems could still be a solid choice especially if you were working on a tight budget. You might choose a less expensive AMD chip + mobo to have more of your budget available for a beefier video card, and as long as you were going with a mid-to-upper-mid range processor you'd get quite reasonable performance. The gap is so wide between their current offerings that it's basically insurmountable, especially when heat and efficiency are factored in.

That was the last AMD processor I have used in a build though.

I miss my old Deneb/Thuban build  . I still have an Asus Sabertooth board that no one wanted (but someone bought the CPU so  ), I wonder if grabbing something like a 1050t would be worth it. Aren't the Thubans theoretical better than Visheras?

Is it simply a clock speed issue or an architectural one? What if I water cool and try to crank a Thuban up to 4.0ghz? The article seems to be using the stock 1100T speed and even when the FX8350 beats it it doesn't seem to be that far ahead. I mean this is really dumb and my i5 is fine, but nostalgia calls and I'm full of dumb build ideas

If you can get the chip for cheap enough it's worth a shot. Weird that reddit's still all-in on AMD. Reading some niche hardware forums it seems like most AMD diehards have finally given up and switched to Intel, although I did see a post recently when one AMD-haver was showing pics of his ridiculous dedicated VRM fans and rear-socket fans to another poster. This wasn't even for suicide runs, it was just so that he could overclock the chip enough to almost compete with a haswell setup.

Reddit is getting better. r/Buildapc is pretty much all Intel now, the occasional AMD nut gives advice but they are quickly shut down. The source of a lot of issues is that the head mod and build advice guy of r/PCMasterRace, the biggest reddit PC gaming community, is also the owner of both r/AMD and a raging Intel hateboner. If you want to see lovely AMD builds and conspiracy theories (Anandtech and Tom's Hardware are PAID by INTEL to make their stuff look good, see?! Something something antitrust lawsuit), check out the PCMasterRace builds.

Zen is either the promised land or a smoking crater, AMD doesn't have a future if Zen is bad or not good enough. A timed release with 400 series cards might help them likely 2016 late Q2, but 2016 is pretty do or VIA.

It really *is* the promised land if they can pull it off. I happened to poke through ifixit earlier today, and here's a shot of the entire mainboard of the new Macbook: That's it. From top to bottom. Processor is on the opposite side, but there's an Intel Core-M, non-Iris graphics, DDR, everything. But man, if Zen is comparable to the contemporary Intel architecture, that would be a coup that AMD could easily orchestrate.

Okay, I checked some components on the mobo using a laser thermometer and they're getting close to 100 degrees C under load  (under 60 when mostly idling)Also, I'm pretty sure now that this isn't a new problem that appeared after I changed the cooler, rather it has been like this from when I bought the new CPU. The CPU still is faster than the old Phenom II I had, so I guess now I'll just keep using it until the mobo to frys itself.
