AMD Offers Full Details and Performance of Zen-Based Naples Server Platform (hothardware.com)
MojoKid writes: AMD lifted the veil this morning on architecture details and performance expectations of its next generation Zen-based server platform, codenamed Naples. Naples is an up to 32-core, 64-thread variant of Zen, targeted at enterprise and data center applications. The processors will feature eight-channel DDR4 memory controllers (with up to 16 DIMMs attached per CPU), with support for up to 4TB of memory and 128 lanes of on-chip PCI Express connectivity. In a 2P (dual processor/dual socket) configuration, Naples offers up to 64 physical cores (128 threads), access to 32 DIMM slots, and aggregate 16 memory channels. Versus a 2P Intel Xeon E5-2699A V4 based server, the 2P Naples setup ends up with double the memory channels, a higher total memory capacity, more cores (20 more physical cores, 40 more threads), and 48 more available PCI Express lanes. AMD's performance comparisons at its tech day event pit a 2P Naples server with 512GB of DDR4 RAM up against a 2P Intel Xeon E4-2699A V4 configuration with 384GB of RAM. The Naples system had a higher memory capacity and that memory was clocked much higher too -- 2400MHz versus 1866MHz. The Naples system has more cores, and with SMT on, can ultimately process more threads as a result. The AMD Naples system also has double the memory channels, further improving peak memory bandwidth. In its demos, AMD used a seismic analysis workload, which involved multiple iterations of 3D wave equations. According to AMD, the test taxes the entire system, including CPU cores, memory and I/O. In this demo, the AMD server system completed equations roughly 2.5x faster than the dual-socket Intel Xeon server. Expected price points weren't given, but Naples processors and servers should be available in Q2 this year.
Chattanooga tried to set up a city owned ISP a few years ago because the local monopoly was terrible, and the state government legislated to prevent them doing it.
That's what happens when money dominates politics.
That's off-topic. There's nothing about CPU upgrades that demand a comparison to internet speeds. There are TONS of workloads that don't require LIVE access to a saturated internet connection.
And those that do? BUSINESSES PAY FOR IT.
My brother wasn't overseeing terabytes of medical info crossing through his building in a day, on a user-grade cable modem.
There is a massive benefit in situations such as a lot of parallel tasks using the same dataset shared in memory. I/O only matters with getting things in and out and a lot of tasks are CPU bound instead of I/O bound. The demo task they used, processing of seismic data, is a good example of that sort of task. Think of things like applying the exact same filter to a few million audio tracks for an idea of how parallel the tasks can be, and think of mixing based on location and time of millions of audio tracks to get an idea of how good it is to do it all on the same machine with shared memory.
Fun fact: Quad sockets are SUPER-RARE.
Go ahead. Try and Google for a quad motherboard. They haven't made them since like... the Athlon 64-era Opterons. The boards are MASSIVE. You can't fit 128 DRAM slots on a single board. (And who wants to BUY that many?) There's too many traces and the board becomes super expensive from the extra routing layers. The board is also going to flex under any kind of weight, and the larger the footprint the more important the mounting becomes (going from casual "bolt it to the wall." to only professionals can service it carefully lest they flex it and snap a delicate trace.)
Some of the larger boards (ala more sockets) are connected into sub-modules that stack perpendicularly into a specialized transport bus. The bus / message-passing chips are also pretty damn expensive.
The trend has clearly been moving away from MULTI-CPU, and toward MULTI-CORE. The same motherboard, you buy better and better CPUs with more cores as you need. All the cores are together. There's no motherboard manufacturer based chipset. No huge message piping. It's all there in the L1, L2, L3, (L4). And it's the SAME or MORE CPU cores than before. 4 sockets with 4 cores vs 1 CPU with 16 cores? That's a no-brainer. It's way more cost-effective for 99.99% of people. And you can upgrade ONE (or two) CPUs instead of four which adds up fast across many stations.
Chattanooga did set up a city owned ISP, EPB, the Electric Power Board of Chattanooga. EPB offers some of the fastest, most reliable, Internet service at extremely competitive prices. So when EPB began thinking about expanding to other underserved communities in the Chattanooga area, it was a real threat to the incumbent duopoly: Comcast and AT&T.
The Tennessee legislature couldn't prevent Chattanooga from setting up its own ISP, but what they could do is prevent EPB from expanding their service area beyond the city limits. So areas just outside Chattanooga have some of the slowest Internet service, and it's all thanks to lobbyists for AT&T. Thank you, Tennessee Republican legislature, for protecting the profits of AT&T by protecting them from competition by a city owned utility.

Communications network (e.g. phone) surveillance, seeking keywords. Yup, it gets done. A lot.
APK quotes people (including myself) without context and should not be trusted. Just thought you should know.
The Xeon line has been pretty lame for the last couple of years. It's nice to see some competition.
Really? You should tell all the people that are making quad socket servers today.
Maybe you should try following your own advice.

So market failure caused by anti-competitive politics. And that in the "home of capitalism". Pretty bad. I wonder how much corruption is involved. Corruption kills societies.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
Still rare, still expensive, still fragile, still hard to service and upgrade, still not worth it except for some edge cases.
Quad (and octa) core servers are the moon rockets of IT. Yes, they do exist. No they are not common. Only for very, very special missions.

The Ryzen CPUs support ECC, but the parts haven't gone through the server level validation for it. It's up to motherboard manufacturers whether or not to support it, and I expect we'll see "home server" 300 series boards with ECC support in the near future.
The Naples parts will absolutely support ECC. It's pretty much mandatory for server parts these days.
Never underestimate the stupidity inherent in all human beings.
wow better tell the guys where I work that at least 400 of our HP servers are Super Rare!
Ryzen supports ECC. Even on the desktop, if the mobo supports it.
That seems to be mostly a problem in the US. In Europe, slow Internet is something you usually find in the countryside, but not in cities. Market failure?
Broadband have monopolist tendencies everywhere, but I think the real market failure in the US is because the biggest providers are cable networks. You're basically asking them to saw off the branch they're sitting on. Here in Norway telcos and xDSL was big and power companies were the first to push fiber, cable is also a player but they must remain competitive. They still want to make profit but if they can make more money selling you even faster broadband they'll do it. The mean download speed is now 47 Mbps (36% YoY growth), median is 27.7 Mbps (11% YoY growth) and no caps, it's something of a fiber rush as they're all doing that now. It has nudged out xDSL and cable as the dominant access technology.
Rural areas struggle more but there's variations of public/private/community funding, our cabin now has fiber. At the base is a commercial provider, but the project also had public funding (and thus a public budget), we paid an extra connection fee and everyone had to dig from the main road to the wall themselves or pay extra for that too. As part of the whole deal all permanent residents were offered fiber, cabins only if they were in close proximity to other routes. The residents want it, the community wants to be attractive and not a backwater hick, the company will make money on it in the long run... nobody's really against rolling it out, the math just needs to be there.

Still rare, still expensive, still fragile, still hard to service and upgrade, still not worth it except for some edge cases.
I bought a bunch about 6 years ago (not the 10 the OP claimed). They were quad socket Opterons with a quarter terabyte of RAM. Rarer than 2P, but available from a well known manufacturer (SuperMicro) via vendors already on our systems. Not rare. They weren't expensive either, well, not in terms of bang for buck doubly so considering the space taken up (they're about double the density of 2p systems). They were fine to service and upgrade, not that that really happened, but you slide them out of the rack on the rails, pop the top and there's stacks of nearly arranged DIMMS and CPUs in neatly arranged sockets, just like any other 1U system. The main thing was the lack of wasted space in the 1U case.
I was always kind of surprised they weren't more common. Some people seemed to prefer "blade" servers for compactness which were vastly more expensive and had less grunt and memory per U, and impossible to upgrade piecemeal. Those 1U supermicros were a hidden gem.

Historically one of the huge advantages of AMD is that ECC has been available on much lower end parts than Intel. I hope that continues.

It doesn't magically become not corruption when it becomes legal.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
The article doesn't mention support for error correction for the RAM. If a bit gets flipped somewhere in a massive research project running on such a system with 4 to 8 TB RAM, the entire project could be ruined.
ECC, anyone?
All the AMD processors support ECC. You need to explicitly criple it like Intel does not to. It need to be certified with the motherboard though, and most consumer motherboards don't do that, and many also don't provide the tools to access if any error-corrections are done.
Nor does it become corruption because money was thrown at politicians.
It becomes corruption when politicians pass laws and regulations because of that money.
I dont live in the Seattle area so I dont know which politicians are responsible for granting the Seattle monopolies without some sort of public compensation (such as contractually good internet service) but I do know that if I lived there I would know exactly who was responsible. Its probably the city council thats holding the keys to the franchise agreements but thats not always the case.
The current Seattle city council:
Councilman Lisa Herbold, Democrat
Councilman Bruce Harrell, Democrat
Councilman Kshama Sawant, Socialist Alternative
Councilman Rob Johnson, Democrat
Councilman Debora Juarez, Democrat
Councilman Mike O'Brien, Democrat
Councilman Sally Bagshaw, Democrat
Councilman Tim Burgess, Democrat
Councilman Lorena González, Democrat
If its not the city council then the next most likely person responsible is the cities Mayor or a member of his office:
Mayor Ed Murray, Democrat
Vote out the fuckers responsible, even if they are a member of your favorite party. If the State of Washington steps in like they did in Tennessee, then start voting out the State legislature as well. Form a community action group. Spread the word that these franchise agreements are why these fucks are going to lose their next election.
"His name was James Damore."
Found the Intel fanboy. How do you expect them to compare to a processor you can't actually get?
As a long-term AMD user, I was blown away when a system was "upgraded" from a dual-core to quad-core chip started behaving even worse with VM's, which led me to discover that the Quad-core chip didn't support VT.
Looking into it more, I discovered that Intel does this a *lot*, with sprinkles of support for this and that across a huge range of chipsets. With AMD, I haven't found a chip without AMD-V/VT-x in forever.
Now this was a bit of an older CPU for sure, but it seems that even newer Intel CPU's one has to be very careful that options like VT-D and others aren't neutered out.
