Well then, only for you I’ll dust off a folder with AS SSD when I’ll be testing the next mainboard unit - don’t blame me if it says something like negative 1.21 sec as latency
I’ll go look where I have the previous results of the chipset-supplied PCIe lanes.
Found the X570-Chipset slot results, Optane 905P 480 GB #1 was drive D: and got its lanes via CPU (PCIE 3):, Optane 905P 480 GB #2 was drive E: and was installed in PCIE 5 of the Taichi (chipset PCIe slot):
Yeah, keep in mind that that was with earlier AMD chipset drivers and BIOS versions (late July).
I’ve tried to keep the results “clean” (unplugged ethernet cable and made sure Windows wasn’t doing anything in the background), but I’m not Gamers Nexus and repeat each test 100 times and establish any margin of error etc.
Also note that I used PCIe-M.2 adapters combined with Intel’s OEM M.2-to-U.2 adapters so not exactly an “ideal” setup regarding signal integrity but it worked just fine and didn’t influence anything compared to the M.2-U2 adapter directly installed in an M.2 slot supplied by the CPU.
Exactly one of the main reason why i don’t really understand,
why people limit their brand new Ryzen3000 cpu,
by buying an older chip set board.
I mean sure if you already have a previous gen board,
then upgrading the cpu for more cores makes sense.
But if you buy a new setup, then why bother with previous gen boards?
@ MisteryAngel It’s probably because while some people doesn’t even notice SATA SSD and PCIe SSD anyway, but the same socket with newer CPUs makes possible to upgrade from old computer with less budget.
I myself, of course, will buy 3950x with X570 board
Yup makes sense for those who already have like a X470 board with 2700X,
and want to upgrade to higher core count chip.
But for those who buy new setups, i see allot of ¨tech tubbers¨ recommend,
to get an cheaper B450 board with a 3700X /3800X etc.
And i just cannot really get at all.
But get back to your question, on X570 + 3000 series cpu,
the dmi between the cpu and the chipset is 4x gen4.
So there basically is more bandwith available to the chipset / pch.
Somehow I got the feeling it was time for an early fall/autumn cleaning of the other system that currently uses the Optanes so I might report back a little sooner than in a few weeks.
Yup, I already know that but I don’t know more appropriate term for this. I can’t call this Southbridge either lol(also derived from Intel). The term “Chipset” has somewhat confusing meaning.
The reason older AM4 boards are recommended as an alternative is there are an extra 4x pci-e 3.0 lanes from the cpu dedicated to an m.2 slot, so the chipset providing pci-e 2.0 doesn’t effect most people any more than Intel’s mainstream setup does.
Unfortunatey, I didn’t have the choice to get any other motherboard model on the entire market due to wanting AMD with Thunderbolt 3 with 2 x 100 W Power Delivery via a Gigabyte GC-Titan Ridge AIC.
@aBav.Normie-Pleb thanks! It seems it’s almost same either on cpu or chipset lanes. BTW, how about X570 taichi? I’m thinking of using this for my VFIO system.
Since I only use a desktop OS on it I can’t say anything about its stability regarding virtualization.
But for that desktop use I’m quite happy with it (had the bad luck that my first unit was defective out of the box and it wasn’t an obvious defect so it took some time to find that out).
I wrote a little report on how I chose it, since I wanted Thunderbolt 3 I had to go with ASRock so it basically was a duel between the ASRock X570 Taichi and Creator (open the link for better text formatting):
