What’s the current theory why it requires more power? Something to do with the 3000 Ryzens or something to do with PCI Express 4.0 or both or something else?

I dont know the answer to that question. But I am interested in finding out myself. Ive put off far too long an upgrade. Just imagine the jump ill see going from a 8120 / 990FX to a 3600X / X570. So ya, im interested in your question.

X570 shouldn't offer any new features over X470, so I can't imagine it being much more than a rebrand of X470 + PCIe4.0 . Unless they're going to come in with USB 4.0 support. Would that expand power usage?

I’ve read it (X570) will take approximately 15 watts to power whereas x370/470’s take 6-8 watts to power.

I guess if you dont do anything then q9650 sata300 should be fine.

I have been stuck with a 3930k for almost 8? years before switching to a 2700x,


i think intel will still be better than ryzen 3 but i can always dream.

I dont need pcie4 (i dont think!) ddr5 would be nice tho, i only run a 30$ set of 2x4gb 3200mhz and runs everything very fast and cool. Ill wait for ryzen 3 for that too. :0

Why is the 570 rumored to require twice the power as a 370/470?

First:

X370 = 8W TDP
X470 = 6.8W TDP

It's only a rumour as yet. The rumour mill has the X570 supporting PCIe 4.0 for the CPU-to-FCH connection, and should have full PCIe 3.0 support for the GPP lanes coming off it. Perhaps a few more lanes then the current 8 too? I could see all that taking a few more W then the current X470.

For comparison the old Intel X58 requires 25W for the northbridge, and a further 6W for the ICH10R. So 15W isn't that much in historical terms.

Further, due to PCIe 4.0, it should be an in-house AMD design. Not Asmedia. Who will continue making the lower tier ones.

As always take with a large grain of salt.

It's probably related to PCIe 4.0, all else being equal. Even if it uses 10-15W that's still an insignificant amount of power/heat.

My guess is that it will fundamentally be similar to X470 but provide a PCI-e 4.0 connection to the CPU and then output PCI-e 3.0 lanes. I'm curious to see what die size is necessary for this (since most of the logic is now on the Zen SoC) and what node they use. PCI-e 4.0 to 3.0 muxing might be more power intensive? Not sure.

I doubt I'll see any reason to upgrade to X570 if BIOS updates enable PCI-e 4.0 on the top slot of 400 series boards (and maybe the primary m.2 slot?). We could be seeing an interesting combination of 4.0, 3.0 and 2.0 PCI-e on BIOS updated 300/400 series boards. Very interesting times.
