The Ryzen "ThreadRipper"... 16 cores of awesome

I guess I forgot the /s on that post. It was a joke.

Some bad news, though not entirely unexpected:

Yeah that has to be obvious to anyone. Expecting to be able to use an old cooler on these things is just silly.

 

[w3rd]

Maybe some peeps can MCM their coolers...

Just solder a bigger piece of copper under it!

 

[krumme]

Just undervolt and run without cooling

 

[Markfw]

I have a welder, and a Prolimia Megahalem (if thats spelled right) has a pretty big bottom, and 12 heatpipes. I could probably make my own !

4094 pads!

Wow, thats huuuuuge.

I assume Corsair H105 would not fit to cool this?

 

[ddogg]

Hopefully EK or BP releases a waterblock for this thing. Thing is so massive it might be as big as a monoblock.

 

[krumme]

Wow, thats huuuuuge.

The third time i told here its nothing compared to the coolers for skl x

Well, the 4x8 kit is just about twice the 2x8 kit I got for my Ryzen's, $360 total.

Yeah, it seems that most people will have to stick with single-rank. We'll have to see if the effect of dual-rank memory is as pronounced in quad-channel as it is in the case of dual-channel Ryzen.

Robert Hallock confirms 256GB maximum supported memory on Threadripper.

So, RDIMMs are supported? I don't know of any UDIMMs at 32GB, which is why Intel's HEDT lineup was limited to 128GB if I recall correctly.
No mention of ECC in the video, but if RDIMMs are supported ECC validation from AMD and motherboard vendors doesn't escape the realm of possibility.

 

[Atari2600]

Good.

To be honest, anything less than 256GB on a platform such as this would be just asking for trouble!


[Please don't interpret this as me saying everyone needs 256GB, I'm not. I'm saying a not insignificant proportion of possible users will need it or will consider the potential for expansion when deciding whether to buy or not.]

So, Alienware's box is out end of July, but they won't say when the rest of us can get one?
"the fastest clock speeds we could put in a chip" ...and no one asked what those were?
I mean, I expect them to not answer, but still....

AMD PR
http://www.amd.com/en-us/press-releases/Pages/amd-exhibits-pc-2017may30.aspx

The X399 chipset motherboards for the new socketTR4 platform are designed for the highest tier of PC enthusiast society, who demand cutting-edge features such as 16 core/32 thread processors, quad channel memory with support up to 2TB of RAM1, superior IO, and who choose the ultimate processor and motherboards as an extension of their personal brand.

1. Linux based operating system and 8x 256GB UDIMM DDR4 memory required

I'm not sure I want to know just how much 2TB of ram would cost.... More than most cars likely.

 

[Malogeek]

That's some serious VMs....

That's some serious VMs....

Speaking of VM, does anyone know if VMware/Xen/QEMU have been updated for Zeppelin's topology? I don't imagine it will be pretty if a VM dedicates two cores and those cores are core3 and core4 in different CCX.

So if the Dell system is due for sale in a month...then there must be a few of them getting made already. Someone break into a Dell warehouse and bench one of them in the dark of night....

Well, the Dell is due for sale end of July; when those will be delivered is a different question :^/
There are likely only a couple of items we care about. First is how high the chips can OC. The Area 51s are supposed to come OC'd, so looking there is a good move. Given that the different tdps are apparently related to memory speeds, and that the rumors thus far hint at a lower turbo, I don't expect it to hit 1800X territory, but it's good to keep in mind that the IF will only need to be 1/6th of Epyc (assuming the connections really are chip-to-chip and not CCX-to-CCX), and I saw one review of Epyc with more than one turbo clock, so, who knows what TR is really going to look like.
The other is how well the mcm approach actually works. Here, Epyc numbers will help. https://www.heise.de/newsticker/meldung/AMD-Epyc-legt-los-3748615.html

The Cinebech value first swayed between quite a decent 5400 to 6000, but AMD technicians were still working on the configuration and ultimately values came to 6879

I see Cinebench scores for the 1800X coming in at ~1600. 6800 on a 2p system would indicate that we're definitely not getting linear scaling (850 is less than 2.2/3.6 * 1600). That performance is low by about 13% or so, and that's without even asking questions about what tweaking they were doing from the original 5400/6000 numbers. Some of that is going to be 2p scaling, but....

So, from what I can see, "best" (ed: non-optimistic) guess for TR is ~5% clockspeed deficit to 1800X and ~10% throughput scaling losses, which leaves room for the 12-core SkylakeX to be competitive. I may well wait until they can fix their single-core Turbo ceiling. So many things I do are stuck on single core (stabilization, motion tracking) while the stuff that will definitely get faster (compression) is off-line time anyway. I'll wait, but I am skeptical whether it'll be right for me.

256GB is the current limit of 8 slots of memory with 32GB UDimm sticks on the horizon. Threadripper is going to tout ECC support (as opposed to Ryzen) but not Registered ECC. That is EPYC only.

THE CPU itself will support up to 2TB of memory but I doubt many chips will live long enough or DDR4, for that to happen.

AdamK47, nice touch with the ThreadRipper II logo. Who knows? Maybe version II might be that big.

Are you going for the 18core/36 thread SkylakeX when it is released later this year or are you going to Threadripper?

 

[Shivansps]

The problem with TR is that it offers zero new features, except for the pcie lanes. Considering that most people will be just fine with a 8C ryzen.

I'll know by the end of July. I could go either way.
