I would have loved for them to use PLX Chips to break out and allow for higher I/O. Then I realized it wont happen because : Cost/Every company has discriminators between their product lines. AM4 will not be getting the I/O of threadripper, threadripper will not be getting the I/O of EPYC. That's the discriminator for AMD. Also, as it has been detailed, you do get break out from the chipset on AM4 from PCIE 4.0 to more broad based PCIE 3.0/etc. So, they gave you half of what you wanted.
-its not what I want, it's what they CAN do. There are a lot of people out there that also want AM4 ATX server type boards with OOBM on them and there are just barely a couple of hard to find products out there.
Sure, but if you break it down or out it adds cost. Threadripper gives 8/16/8/16 + 3 dedicated nvme. If you need more I/O buy one. If you need more than that get EPYC which into the server market uses PLX switches.
I have 5 cards in mine (using the PCie 2.0 slot too) + 3 nvme drives. I beg to differ.
Again, if you have a need the platform, you have a need. If you don't, I don't think a person will understand or can comment on threadripper.
I was excited about PCIE 4.0 like you because of expanded I/O breakouts. In its current form, I'm not sold on it. NVME on PCIE 4.0 is not a selling point for me but will be for some.
--and, like I said, there ARE SOME niche users out there for whom such a product would be useful. However, would your PCIe I/O needs be that greatly affected by running the four cards at 8x PCIe 3.0 behind a PLX chip that is only 100% bandwidth subscribed? How about your memory bandwidth needs? Unless you have more than 64 GB of RAM, is dual channel DDR4-4000 going to hold you back much from the quad channel RAM that you currently use that likely tops out at 3200 or less?
Look at the pic. PCIE Gen4 slots board.. That's for Rome. Your statement is incorrect. Threadripper will get similar but cut down treatment.
---I'm looking at that board. Unless there are some small repeater chips on there that I'm not seeing (which might be the row next to the first slot), it violates the trace distance rules for PCIe 4.0. there is no need for plx chips due to all the lanes that EPYC provides, just repeaters.
See above. Where's the PLX switch?
--It's EPYC, no place needed, just repeaters for distance needs.
Why do people keep trying to re-write facts towards their own opinion? The discriminator is I/O and memory bandwidth. Something that has already been detailed.
This is literally the same amount of I/O but with Gen4. This doesn't suit my needs. I will literally buy a Threadripper over this if the price isn't right. I literally need two Ryzen systems tied together with high speed enterprise nics to even come close to one threadripper. The same holds true above. There aren't even any PCIE 4.0 mainstream products.
X570 :
Isn't that different from :
I hit the same I/O restrictions. What are people talking about? That 3rd PCIE slot btw will likely only be usable if you don't use other I/O. You're getting the same package but with PCIE 4.0 labels and higher core count. For some this will be a godsend. For me, it's somewhat of the same package
--again, for YOUR PARTICULAR use case.
