I have to be honest and admit that a 15W TDP for the chipset worries me. Considering it will almost certainly mean active chipset cooling makes me think about pairing a Ryzen 3000 with an X470 motherboard. Not what I had in mind.
Yeah I have to agree that it kind of seems weird to need active cooling on the chipset, been years since I've had to worry about the 'whine' of a tiny little fan.Quote:

Apparently it's all down to the pcie 4.0 signal doublers (i think, i can't remember and can't find the article i saw it on or it might have been Jim from Adored).
They really are hiking up the power and thermal requirements.
Active cooling is no biggy as long as they have decent fan profiles on that little thing so it works only when needes.
To call it a backward step is a bit *hand out wha?* to me
You'd probably have to be hanging a lot of stuff of the chipset for it to get hot enough for the fan to be needed, IIRC the CPU itself supplies enough lanes to run two PCIe 3.0 GPU's, two PCIe 3.0 NVME drives, two SATA drives, and four USB 3.1.

The rumours are that it's for nvme raid. Think it was buildzoid that let it slip.Quote:

Yup just imagine that the bandwidth of this chipset is more than treble a standard chipset in use right now - and you can do some awesome things with that. nvme drives are going to love that bandwidth for example and I'd imagine this release is going to heap pressure on Intel as their chipsets are a heap load less badnwidth enabled
If the fan is semi-passive, or has good fan control (unlike that recent asus AIO 360mm cooler) then it shouldn't be an issue for most users (do people RAID SSD's? Technically it can be done, but does anyone bother? if that's the case, and if the fan is only needed for RAID, then the fan only has to be quieter than a couple of hard drives).
OTOH, if it is for signal boosters, is only getting PCIe 4.0 to the closest GPU really that bad? Stick an m.2 port on the back around the RAM, and that's 90% of use cases for the extra speed covered
On the X470 16 lanes of PCIe 3 were dedicated to GPUs (either 1X16 or 2x8, the latter for Crossfire) which were handled direct from the CPU. The X470 chipset controlled 8 lanes of PCIe 2 for other devices:Quote:

X570 block diagram for comparison. Loads more bandwidth available (remember PCI Gen4 at least twice as fast per lane)

Technically x16 PCIe 4.0 is equivalent to x32 PCIe could you have 4x x4 PCIe 4.0 to get the equivalent of 4x x8 PCIe 3.0?
I doubt it would work that way but one can dream!
Just oodles of bandwidth. See other article on here about a gen4 nvme SSD with 5GB/SQuote:
