AMD Reportedly Launching Threadripper Pro 7000 Series on October 19

Of course, you could only have 2 SODIMM slots instead of RDIMM or LRDIMMs, but that would defeat the purpose of buying an EPYC. In fact, mini ITX sacrifices the IO capability even more than it sacrifices memory capacity and bandwidth. I ask again; what workload needs 96 cores, but can make do with 4 channels of DDR5 and 1 lane of PCIe?

I dunno. I haven't seen benchmarks of the current EPYC line with different memory channel configurations. It is highly likely that different applications are affected differently and my personal guess is that only a minority of apps are very sensitive to memory bandwidth.

It presumably also depends on whether you get the EPYC chips with the 1.1 GB cache.

In any case, if you absolutely need the small mainboard you have no choice. A 96-core CPU with dual-channel will still be faster than a 16-core CPU with dual channel.

I still question the use as you sacrifice memory capacity as well which is a bigger deal than the bandwidth. As far as workloads's sensitivity to memory bandwidth is concerned, AnandTech ran some tests on a Threadripper Pro 3995WX that was configured with only 2 DIMMs out of the box. Some workloads didn't see an impact while others were slowed down by a ridiculous amount.

I love the power options coming down the pipeline. I like to see the progress of the CPUs. What is wrong with inserting a supported 600HP into a Honda Coupe? If the engine fits and has the correct supporting parts. Why not. Everyone does not desire big care, but small cars with power, and done correctly is a win-win for the end-user.

IF the Ryzan 7850X processors supported fully registered ECC RAM and at least 2 full X 16 PCI slots. Then I personally would not have a need for something like a Threaripper. Do need 7 plus fill PCI lanes - nope. BUT I do like the option to have at least 2 full PCI lanes, for any future upgrades. It comes with a cost for sure.! But I like to build my systems based on just having a little room.

I mean it's up to you to know if your workload is sensitive to memory bandwidth. I don't see the point of artificially limiting the capabilities of the processor. You're also giving up on the IO options.

We both have a point.

I want to take advantage of the full power of the Threadripper, but at the same time, with 2 or 4 DIMM, 128Gb to 512GB of RAM is plenty for any and everything. The lower-grade CPU does not support that kind of RAM or PCI I/O. I have to jump to AMD Epyc or Intel Xeon.

I see your point, but mini ITX would severely restrict the PCIe lanes available from an EPYC. Micro ATX would be better. LRDIMMs also have a price premium compared to regular RDIMMs so there's that to consider as well.

I agree with ya!

I personally want to see AMD do better when they are rolling out these products. I believe they can offer a better motherboard for the Threaripper in the smaller format. I believe the Ryzan smaller chips could offer the 2 full PCI lanes and ECC Registered support. I believe there is a huge hole that forces people to get a Threaripper chip and never fully take advantage of the processor.

Right now, if I upgraded chips, I would step into the 7XXX, but let's first see the motherboard to come. Right now, I get a sense that I will do as someone else has mentioned. Wait on a 5XXX to hit the used market and jump on it from here.

Yes, the limited PCIe lanes from the CPU are perhaps the biggest drawback of mainstream desktop sockets like AM5 and LGA1700. In 2009, AMD's AM3 socket had chipsets with 42 PCIe lanes. We have regressed since then.

Totally agree. connecting sata drives or all 4 NVME should not limit anything. There should be enough PCIe lanes for every device or connector on the board, or why even put them on.

Yeah, but keep in mind that this is registered RAM (on the Threadripper Pro). 4 slots will carry you pretty far. Not sure what the theoretical limit for DDR5 registered modules is, but it will be at least 4x of UDIMMs.

Micron has 128 GB DDR5 RDIMMs. 128 GB DDR4 RDIMMs exist as well so I would expect DDR5 to exceed that a couple of years later.

NEI...Not enough information.

*Need to go to an EPYC socket to support DDR5 memory @ 8 channels.

*Moving to 96 cores on 8 channels would drop mem bandwidth down to 5000 series throughput per core.

*At least 12 mem controllers required to prevent a bottleneck on EPYC DDR5 standards which would require a new socket.

Can AMD deliver a new socket and and 4 more memory controllers per core? Sure. Would they? Their still using Tick/Tock and the additional mem controllers would require an architecture change along with a new socket.

I would venture a guess they'll stick with 64 cores, max, for this cycle.

Threadripper Pro uses the same IO die as EPYC so enabling 12 channels won't require anything new.

When using the Epyc over the Threadripper Pro, since the speed of the processor is slower. Is this taking a step in the wrong direction? If I wanted to use a MATX motherboard with an Epyc Processor.

The Zen 2 and Zen 3 based Threadripper Pros were OEM only products. In other words, you couldn't buy them as standalone CPUs; instead, you would have to buy a whole system like the Lenovo ThinkStation P620.

???? My local Microcenter sells the Threadripper 3XXXX / 5XXX processors as complete stand-alone processors.

I forgot that they had released them to retail; they were exclusive to OEMs for about seven months.

Also it seems you need to be careful buying oem chips 2nd hand as they may be vendor system locked. I see this alot browsing ebay.

Absolutely! I agree 100%.

I would try to find, New Old Stock if at all possible.

What kind of locking is this, are the processors locked to one motherboard, or to one brand, such as Lenovo?

Here is one article that I found on the topic https://www.tomshardware.com/news/lenovo-psb-locks-threadripper-5000-on-p620

 

[unwind-protect]

Brand. They actually "bind" to a brand the first time they are inserted into a motherboard (the locked CPUs, they are delivered unlocked).

I still don't understand who these are for. EPYC is for servers, the 16 core 32 thread regular Ryzen 7950x is for home servers and people who need the threads for work... I just don't understand who buys Threadripper, small businesses that don't need EPYC but need more than 16 cores? That's all I can think of lol

the one who uses CAD/CAM software need it, we need cores, real cores; for us:
_ EPYC, Xeon is something for server
_ ryzen, i9 13900ks is something lack power, yes it is.
_ hyperMill, PowerMill will eat all cores and threads that system has.
so, we need 100 core - 200 thread in single system to calculate tool path, threadripper is da best for now.

I love the advancement of technology. But for some reason motherboard manufacturers only support the Threadripper Pro processor in the larger format (ATX/E-ATX). No issues finding a smaller format ITX or MATX motherboards for the trivial Intel Xeon processor. For whatever reason, the AMD Threadripper is not supported in that manner. I beleive a lot more interest can take place if the motherboard manufactors supported the Threaripper Pro in the smaller format. To allow the end user to have smaller format workstations. Most workstations these days are only a few at most GPU deep. It would be extremely nice to have a smaller M-ATX Threadripper Pro motherboard with four full PCI lanes and 8 RAM slots. Asrock Rack W790D8UD-1L1N2T/BCM (https://www.asrockrack.com/general/productdetail.asp?Model=W790D8UD-1L1N2T/BCM#Specifications) makes this exact motherboard for the Intel Xeon Processor. It will be intteresting to see if they offer this same format motherboard in this exact layout.

That motherboard alone, makes me want to see what the leap from Threadripper to Xeon would actually be like. Just for the reason of a smaller format worksation.

fashion case doesn't matter when in heavy work, even extreme-plus-E-ATX is fine.
