Very likely because they are paid to or benefit from shitting on AMD via share price shilling. If you'd banked most of your retirement in Intel/Nvidia shares, you'd shit on AMD at every chance you'd get, wouldn't you?
It's easy because that is two main consumer facing market sectors with one company. Intel doesn't make AIB dGPUs and Nvidia doesn't make x86 CPUs. AMD does both so is the easiest boost to share portfolio when it loses. Also they want a monopoly and hate the idea of competition killing their profits/shares (like AMD is poised to do in CPU market). Considering Vega doesn't look too healthy, now imagine if the fresh start of Rajas' Navi does any good when the process advantage of Nvidia is mostly gone? That's two companies they are taking market share from now.
Now go look at how many posts they make per day here - newfag accounts with over 3k posts in just a year. Some are well over 10 posts per day. That's 99% either a dole bludger posting all day, paid for a job, or a shareholder. That 1% is the actual crazy fan (who are usually unhinged and pretty obvious). It's pretty simple, once you've been here or elsewhere a while you can see the pattern. They do this until people get sick of it, banned or shat on constantly (shintel is approaching this event horizon rapidly), then they'll make a new account, start more gingerly and rinse and repeat.

You don't see this level of rabid fanboyism in almost any other sector - even the car brand fans are not this bad. Even the bikers will rib each other for their choice, but won't break it down to synthetic benchmarks of 1/4 mile speed being 0.1s faster or braking 2ft shorter from 100kmh = x brand is a turd..

That Tyan is fucking sexy. Gigabyte should've had some gratuitous socket porn like Tyan has - socket covers are e-boner killers, like pixelated areas in Japanese porn.
16x Sata functionality and all lanes are making me moist. I have not been so excited for a new CPU/platform since Athlon 64 days. Everything since then (while sure, some great performance jumps) has been pretty meh. Slightly faster PCI-e, bit more Sata, faster CPUs, onboard everything RGBRGBRGBRGBRGB etc.

I haven't read every comment, word-for-word above, BUT
I did see "NVDIMM" in one list of specs. Allow me to
"leap ahead" (ahem :) and speculate that AMD could be
VERY SECRETLY developing an NVDIMM to rival Optane.

For example, Supermicro have already enhanced their
server chipsets to accommodate NVDIMM logic.

I could be wrong, but why would AMD play all their cards
this early?

NVDIMMs is a 2012 thing. And some of them looks quite funny.

Haha how could I forget politics! Thank you :)

Kek - projection from an 3x Intel system using, Intel and AMD bashing poster with a gtx460, gt610 and a 8800gt laying around amongst a plethora of high end ATi/AMD cards? Sure. I give everyone shit when they deserve it, that includes ridiculously obvious shilling, crappy BGA solder, 'overclockers dream' and stupid hot (when OCd anywhere meaningful) 10 cores that cost twice as much as something that's 10-15% slower, using nearly 2/3rds less power STOCK. No prizes for guessing which product will sell more.
Edit: and considering Vega is getting so much shit because it's taking it's sweet fucking time and is hot as fuck also, Intel is late to the party, panicking while still binning high core parts for spec sheets, doing an RTG and pushing their chips well into 2nd critical zone for release clocks (hence high temps when you go anywhere) and going to be even later once TR is out.

I am going to be frank and say any position of fanboism is not going to achieve anything, people's choices are free will and leave it at that, there is absolutely nothing to gain from it and is just stupid.

Did they mention anything about lower power parts?

Intel's Xeon D SOC parts seem pretty attractive if yo are paying for power.

Their 8 core Xeon D 1541 seems to have similar performance specs as AMD's EPYC 7251. Same core count, similar clocks.

The Xeon D comes in at 45W TDP though, whereas AMD's part is rated at 120W.

That's a pretty huge difference.

Granted, the AMD part supports more RAM and has WAY more PCIe lanes, but still...

I've been casually looking at upgrading my aging dual hexacore Xeon L5640 server from the Westmere-EP (Gulftown) era, and the choices are tough, especially since I pay high Massachusetts power rates.

Xeon D's and the upcoming Atom C3000's seem interesting, but limited total RAM makes them somewhat infeasible, unless maybe I get two of them and max both out at 128GB each.

I'd really like to go AMD this time around, especially since they have good max RAM and ample PCIe lanes, but at 155/170W (what does that even mean?) for the EPYC7281 it might actually wind up being more expensive than an Intel part over its life, if you factor in power use...

The big thing holding me back right now is the $2,000+ I'd have to spend on RAM...

Right!

Those are "non-volatile" because they use a super capacitor bank
which supplies enough power for the DRAM data to be dumped
to on-board Nand Flash, during a power failure event.

The latest NVDIMMs I had in mind are truly non-volatile:
they have no need for these bulky super capacitors.

cf. Intel's Optane / 3D XPoint, in particular,
which is being mounted on the DIMM form factor
e.g.:

http://techreport.com/news/31932/optane-dimms-and-companion-cpus-will-arrive-in-2018

Micron are also in a joint venture with Intel
to co-develop 3D / XPoint memory:

What is the benefit of these NVdimms? Are they used in place of traditional drives or ssd's?

Sadly Supermicro only has DP boards right now. With how many cores these things have, I think most of us could get by just fine with a UP board, and save money on per socket licensing of software.

Gigabyte's board looks interesting, but is it just me, or would it be difficult to utilize all of the RAM slots and the PCIe slots at the same time? That, and the Gigabyte brand dopesn't exactly scream "server" to me. I'd have to think long and hard about it before putting a Gigabyte board in my server.

Tyan claims that board of theirs is an EATX board, but I don't know in what universe that is true, unless they posted the wrong picture. Looks like some funky custom board layout special built to fit inside one of their special cases. I'm going to ave to pass unless it can fit in my Norco case and doesnt need a ton of risers to work properly :p

Gigabyte made some damn good 2p server boards in the Opteron days. I had several. They were (IMO) better than the Asus and MSI boards.

Asus and MSI are also brands I don't necessarily associate with servers :p

Primarily I'm thinking Supermicro and Tyan, and MAYBE AsrocRack, but probably not.

These other brands are gamer brands to me. I'm not sure if I trust them to build motherboards to enterprise/server standards.
 
Jesus. Is there any (legal) way to get 256GB of Registered DDR4 EEC RAM for less than the price of $FIRSTBORN?

At this rate I'm going to be stuck on my Gulftown era Xeon's forever just because of the price of RAM. I already have 192GB of Registered DDR3...

I noticed that when I needed to purchase some DDR4 REG ECC for a xeon. A year ago the ram was a significantly cheaper.

Hmm...


I wonder how much of a market there is for 12x 16GB and 12x 8GB Registered DDR3 modules on the second hand market to defray at least a part of the cost...

With both DDR and DDR2 prices started spiking up after their replacements were introduced due to shortages for the upgrade market for existing systems, but this doesn't appear to be happening to DDR3 this time around...

At least not yet....

a UPS is only meant to keep your systems up until you can switch over to backup power, not for longer term so unless you have your systems set up to auto power down with once systems go to a UPS, then this could be handy.

The greedy ram merchants do this every god damn time AMD has something decent. In a few years it'll be class lawsuit and they'll pay us 10 sheckels back per claim. It's the only thing making me want to hold off as long as possible.
I'm of the mind to get a 'cheap' ripoff 16gb kit for now and hold off until next year for 7nm and moar ram at lower cost...obviously not an option for you to do this way. What do you use all the ram for?

Those NVDIMMs are pretty much a super/capacitor backup to keep the ram alive in case of power loss.
UPS is for backup or shutdown. That said I'm putting a bigger 12V car battery in mine for longer stints and to get me through re-strikes as the line tries to clear (usually trees falling out here middle of nowhere).

For me it's a mix of VM's and the arc ( a form of cache) for my ZFS.

I have a ton of little VM's that really like RAM, but are more forgiving on the CPU.
 
looking at EPYC i can understand Ryzen better: from the start the core was designed to be used inside EPYC.
Ryzen is not a great gaming CPU because it was buit to be a great server core.

There is nothing wrong with Ryzen as a gaming chip, IMHO, unless you are one of those people who like wasting time heat and money on achieving extreme framerates above 60hz :p

If I didn't already have my [email protected], I wouldn't hesitate to build a new system around Ryzen today.

Also, Intel's consumer chips are also versions of their Xeons (or vice versa)

Are you being serious?

A graph tells you nothing unless it starts at 0.

This is why you should never let a marketer create a graph or a chart.

When you start a graph at zero it gives you a proper sense of scale. When you make the axes intersect at non zero values it messes with the scale and is - IMHO - a way to distortion the data in order to tell a lie.

The number one rule of making any chart or graph is that the axes must always intersect at 0, other wise you are misrepresenting your data.

With so few PCIe slots, Tyan's board seems positioned as a compute platform. But neither of those seem suitable for the workstation market: the DIMMs get in the way of long GPUs, and in the server space the DIMMs will be a problem with long storage controller cards as well.

that's because you don't need to use storage device cards with it.. it has the ability to connect 24 NVMe U.2 drivers or 16 sata 3 6gbps drives + 2 sata ports already on the board(connections are on the bottom left of the board on the first picture) and two more on the bottom right edge.

Looks pretty awesome, but overkill for me, even for my server purposes.

I currently have a dual socket Gulftown era Xeon system with two hexacores as my VM server running Proxmox (KVM + LXC). I honestly don't need more cores than that, and I can get that (and many times more) out of a single socket EPYC board.

Dual socket designs are cool if you need the cores, but so much Enterprise software is licensed by the socket, so you wind up paying double for it with a dual socket board compared to a single socket board, so unless you REALLY need more than 32 cores (64 threads) the so flexible socket setups seem to be where it's at.

I'm wondering though, are all 128 PCIe lanes available in single socket systems, or do you need two sockets for that?

Probably moot, as even if single socket halves it, 64 lanes is a good amount.
 
In four die cpus you get 128, in two die cpus you get 64. They use different sockets and packages for each, iirc.
 
Zarathustra[H] said:

Never mind that; I'm thinking about a workstation. Window 10 Pro will allow two sockets, so that's 64 cores and 128 threads, and that board will let you max out the RAM, have two full speed G. Perfect for graphic artists, film makers, game developers, and the like.

What I've been reading confirms that the single socket systems also have 128 PCIe lanes too:

Yeah, this table certainly seems to suggest as much. Even the low core count 1P parts say they have 128 PCIe lanes.

Ryan Shrout wrote this about that:

https://www.pcper.com/reviews/Proce...cessor-Launch-Gunning-Xeon/Architectural-Outl

The IO and connectivity portion of the processor supports eight x16 PCIe links, getting us to the magic 128 lane number.
Each die supports two of them, though one is used for the socket to socket interface in a 2P system,
leaving each CPU with 64 lanes of PCIe, a total of 128 for the system.

Looks like we might have some conflicting information then.

I tend to trust the official spec sheet more than Mr. Shrout, but I could be wrong.
 
Zarathustra[H] said:

Fairly positive Shrout's description is on point. Each die has 32 lanes, 16 of them are used for interconnect on 2P system on each die. So 1P and 2P systems end up having same amount of lanes (128) available.
 
As posted in the article.... 128 PCIe lanes top to bottom in the stack.

For a stand up server, I don't think having 4x u.2 NVMe support is too much. It is overkill for the lower tiered server market but it makes sense to make it an option.

Nope essentially it's 128 no matter what. 2P? 128 1P? 128.

I could picture myself using two m.2's mirrored as a local boot/data store, and two more as mirrored ZIL SLOGs.
