With how big these chips are getting, I wonder if the next iteration will have an HBM last-level cache on chip.

Outside of some very exotic scenarios you are IOPS bound on writes and not CPU bound.
Is that still a problem with cheap NVMe drives that can do 500k IOPS?
Not likely to be a problem if you have FusionIO drives. Likely to be a problem sooner or later on everything else. A definitive recurrent issues on all cloud providers and NAS/network drives.

Gaming? More like consumer market, Ryzen 7 is definitely not suited for gamers, advertising it as such was IMO mistake. Nevertheless Naples can be big innovation in server segment. Also what with ECC? Ryzen can support it or not?
"Ryzen 7 is definitely not suited for gamers" The underperformance in gaming was tracked down to software issues according to AMD. Namely: - bugs in the Windows process scheduler (scheduling 2 threads on same core, and moving threads across CPU complexes which loses all L3 cache data since each CCX has its own cache) - buggy BIOS accidentally disabling Boost or the High Performance mode (feature that lets the process…

Blaming windows is just a desperate excuse from AMD to justify its lack of performances. Don't be tricked by that.
It's possible -and rather common- that there are motherboard issues on the first generation of MB, which again, is not a a valid excuse but a bad thing that desperately needs fixing from AMD and a sign that it's still in testing phase.

#54I've long been advocating for a high i/o cpu with several pcie lanes. 128 lanes will support 8 GPUs at max bandwidth. AMD has positioned itself well.

Not being the top single-threaded performer which is required to push many many hundreds of frames per second != "not suited for gamers". Games in general are more likely to be GPU-bound!! Intel's quad cores are only really required for the pro Counter-Strike players who want 600fps at 1080p just to get the absolute latest frame. BTW they advertised it as good for gaming + streaming (h264 CPU encoding at the same tim…
Pretty much all games are CPU intensive and it's not getting better.
Try running on a cheap i3 from a few years ago and you'll understand your pain quickly.

#56In previous threads there was discussion about Intel processors, specifically Skylake (which is a desktop processor), being superior for server workloads involving vectorization. How will Naples fare on this front?
Desktop Skylake doesn't support AVX-512. Server Skylake will, when it ships. (The Xeon E3 v5 doesn't, because it's the same chip as desktop Skylake.)
Removed the incorrect information from my post. Thanks for the correction.

#57This is what I have really been looking forward to. I theorycrafted a more ideal system for the genetics work a former employer was doing, but didn't get to build it until after I had left there. A quad 16 core opteron system for a total of 64 cores (for physics calculations in comsol). I think that there is more potential use for high actual core count servers than many people realize, so I can't wait to build one.…
Out of curiosity, I thought that genetics was the domain of gpus?
It's quite rare to find GPUs being used in genetics.

#58I think Naples is a very exciting development, because: - 1S/2S is obviously where the pie is. Few servers are 4S. - 8 DDR4 channels per socket is twice the memory bandwidth of 2011, and still more than LGA-36712312whateverthenumberwas - First x86 server platform with SHA1/2 acceleration - 128 PCIe lanes in a 1S system is unprecedented All in all Naples seems like a very interesting platform for throughput-intensive…
> 128 PCIe lanes in a 1S system is unprecedented
Yes, definitely drooling at this. Assuming a workload that doesn't eat too much CPU, this would make for a relatively cheap and hassle-free non-blocking 8 GPU @ 16x PCIe workstation. I wants one.

"IBM did it first"
Well not with HBM (which is DRAM), but huge amounts of L3 SRAM on a MCM... POWER5 I believe.

yes but four modules of ryzen to make this beastly naples chip isn't going to be clocked at the same frequencies. the top end intel chips have TDPs of 165W but 4 ryzen chips at 3.6ghz have a tdp of 65w a piece and you're not going to see a 260W server chip if you want to sell into the datacenter.
I can see a use case for it, as long as it delivers on performance. No one minds high TDP, as long as it offers a performance advantage. Hell, some servers have 4-8 Titans in them, and no one is complaining about their TDP. If a 260W CPU TDP is justified by the performance, no one will care.
I'm more than willing to admit I could be wrong. And maybe Intel will push the TDP envelope with servers as well if Naples proves a threat when things all shake out. Just if Intel hasn't put a ~250W server chip into production I doubt AMD will then again if it performs that much better then there's a calculus there that will need to be done. My prediction, based on no evidence, is that this 32-core chip will be clocked at 2.6ghz and boost to 3.2. Shot in the dark, but given current TDPs that's where I think things might shake out to.
